    Description: Endonuclease restriction (Hind III) fragments of DNA from Chinese hamster X mouse somatic cell hybrids hybridized with proline-rich protein complementary DNA clones only when the DNA was isolated from cells containing mouse chromosome 8, or a fragment of chromosome 8. The evidence suggests that proline-rich protein genes are located at the proximal portion of chromosome 8 toward the centromere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Azen, E A -- Carlson, D M -- Clements, S -- Lalley, P A -- Vanin, E -- AM 19175/AM/NIADDK NIH HHS/ -- DEO 3658-19/DE/NIDCR NIH HHS/ -- GM 20069/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 23;226(4677):967-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095444" target="_blank"〉PubMed〈/a〉

    Description: Cultures of human diploid fibroblasts contain cells that respond to exposure to the first component of complement (C1) by initiating DNA synthesis and growth. The plasma membranes of these cells have specific binding sites for the C1q subcomponent of C1. A fluorescence-activated cell sorter was used to isolate a subset of cells with a high affinity for C1q, and the growth and synthesis activities of these high-affinity cells were studied after numerous replications in vitro. These cells synthesize DNA and grow faster than the parent cultures and low-affinity cells, and they produce two to three times as much protein. About 40 percent of their total protein synthesis activity is directed to collagen production, unusually high proportions of collagen types III and V being produced. These properties and the high affinity of the cells for C1q are retained for at least six cell transfers. This phenotype has the properties expected of fibroblasts in healing wounds and inflamed tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bordin, S -- Page, R C -- Narayanan, A S -- DE-02600/DE/NIDCR NIH HHS/ -- DE-03301/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1984 Jan 13;223(4632):171-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6691142" target="_blank"〉PubMed〈/a〉

    Description: A cloned complementary DNA derived from a messenger RNA transiently present at low abundance levels in early chick embryonic skeletal muscle hybridizes to a messenger RNA present at high abundance levels in cardiac muscle. Genomic DNA hybridization and nucleotide sequence identity of complementary DNA's from both heart and skeletal muscle demonstrate that the messenger RNA's from both sources are encoded by the same gene. The encoded polypeptide is a troponin T sequence which is probably a cardiac isoform. This single copy troponin T isogene is governed by different regulatory programs in heart and skeletal muscle differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cooper, T A -- Ordahl, C P -- R01-GM32018/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 23;226(4677):979-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095446" target="_blank"〉PubMed〈/a〉

    Description: The nucleotide sequence of a human Blym-1 transforming gene activated in a Burkitt's lymphoma cell line was determined. This sequence predicts a small protein of 58 amino acids that is 33 percent identical to the predicted product of chicken Blym-1, the activated transforming gene of chicken B cell lymphomas. Both the human and chicken Blym-1 genes exhibit significant identity to an amino-terminal region of transferrins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diamond, A -- Devine, J M -- Cooper, G M -- CA 07250/CA/NCI NIH HHS/ -- CA 28946/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 3;225(4661):516-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6330897" target="_blank"〉PubMed〈/a〉

    Description: Nuclear estrogen receptor from MCF-7 cells undergoes a time-dependent, hormone-inducible transformation to a form that is less extractable from nuclei and less exchangeable with ligand. This receptor-modifying, intranuclear event is independent of receptor loss (processing) and appears associated with hormone responsiveness (progesterone-receptor induction) in these cells. The magnitude of receptor loss, however, is variable and apparently not a prerequisite for hormone action to induce progesterone receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasid, A -- Strobl, J S -- Huff, K -- Greene, G L -- Lippman, M E -- New York, N.Y. -- Science. 1984 Sep 14;225(4667):1162-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474170" target="_blank"〉PubMed〈/a〉

    Description: Peripheral blood lymphocytes from patients with the acquired immunodeficiency syndrome (AIDS) or with signs or symptoms that frequently precede AIDS (pre-AIDS) were grown in vitro with added T-cell growth factor and assayed for the expression and release of human T-lymphotropic retroviruses (HTLV). Retroviruses belonging to the HTLV family and collectively designated HTLV-III were isolated from a total of 48 subjects including 18 of 21 patients wih pre-AIDS, three of four clinically normal mothers of juveniles with AIDS, 26 of 72 adult and juvenile patients with AIDS, and from one of 22 normal male homosexual subjects. No HTLV-III was detected in or isolated from 115 normal heterosexual subjects. The number of HTLV-III isolates reported here underestimates the true prevalence of the virus since many specimens were received in unsatisfactory condition. Other data show that serum samples from a high proportion of AIDS patients contain antibodies to HTLV-III. That these new isolates are members of the HTLV family but differ from the previous isolates known as HTLV-I and HTLV-II is indicated by their morphological, biological, and immunological characteristics. These results and those reported elsewhere in this issue suggest that HTLV-III may be the primary cause of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallo, R C -- Salahuddin, S Z -- Popovic, M -- Shearer, G M -- Kaplan, M -- Haynes, B F -- Palker, T J -- Redfield, R -- Oleske, J -- Safai, B -- New York, N.Y. -- Science. 1984 May 4;224(4648):500-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200936" target="_blank"〉PubMed〈/a〉

    Description: Smooth muscle cells with 4C (double diploid) DNA content have been found in major arteries. The proportion of 4C cells increases with normal aging and with hypertension. These cells may represent a state of arrest at the G2 phase of the cell cycle or may be examples of true tetraploidy. Flow cytometric cell sorting was used to isolate 4C smooth muscle cells from the rat aorta, and the cells were cultured. Flow cytometry, Feulgen microdensitometry, and karyotyping of the progeny of the 4C cells established the presence of true tetraploid cells. These findings demonstrate the presence of reproductively viable tetraploid cells in a normal mammalian tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldberg, I D -- Rosen, E M -- Shapiro, H M -- Zoller, L C -- Myrick, K -- Levenson, S E -- Christenson, L -- 5-P01-CA-12662/CA/NCI NIH HHS/ -- AG00599/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 2;226(4674):559-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6494901" target="_blank"〉PubMed〈/a〉

    Description: The human malarial parasite Plasmodium falciparum can produce surface protrusions (knobs) on infected erythrocytes; however, long-term culturing of the parasite results in the appearance of knobless cells. In this study it was found that a knob-producing clone lost the ability to produce knobs in vitro. Furthermore, a clone not producing knobs derived from the knob-producing clone regained the capacity to produce knobby cells in vitro. Certain parasite proteins were associated with the knobby phenotype but not with the knobless type. These results indicate that the parasites change in vitro in a spontaneous and reversible manner independent of immunological selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gritzmacher, C A -- Reese, R T -- AI 18695/AI/NIAID NIH HHS/ -- DRR 00833/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6382613" target="_blank"〉PubMed〈/a〉

    Description: The regulation of expression of the family of MHC (major histocompatibility complex) class I genes is complex. Sequence analysis has revealed that class I genes from the H-2D subregion of the MHC (which includes the D and L genes) differ from the class I gene from the H-2K subregion (the K gene) by the insertion of a type 2 Alu-like repetitive element (the murine B2 sequence) within the 3' noncoding region of the D and L genes. The consequence of this insertion in the D and L genes is the introduction of a novel polyadenylation signal, which is preferentially used over the more distal signal, the analog of that found in the K gene. The insertion of the type 2 Alu-like sequence results in a change in the preferred site for endonucleolytic cleavage which is necessary for generating a correct 3' terminus for polyadenylation. The data demonstrate that the type 2 Alu-like sequence has a function; the data also suggest a possible regulatory role of this sequence in the expression of class I genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kress, M -- Barra, Y -- Seidman, J G -- Khoury, G -- Jay, G -- AI 19148/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 23;226(4677):974-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095445" target="_blank"〉PubMed〈/a〉

    Description: The motile activity of growth cones of specific identified neurons is inhibited by the neurotransmitter serotonin, although other identified neurons are unaffected. As a consequence, affected neurons are unable to form electrical synapses, whereas other neurons whose growth is unaffected can still interconnect. This result demonstrates that neurotransmitters can play a prominent role in regulating neuronal architecture and connectivity in addition to their classical role in neurotransmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haydon, P G -- McCobb, D P -- Kater, S B -- HD18577/HD/NICHD NIH HHS/ -- NS15350/NS/NINDS NIH HHS/ -- NS18819/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 2;226(4674):561-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093252" target="_blank"〉PubMed〈/a〉

Regeneration of processes by retinal ganglion cells was enhanced when the cells were plated on glass coated with a monoclonal antibody against the Thy-1 determinant.

    Description: Infectious retroviruses have been detected in 22 of 45 randomly selected patients with acquired immune deficiency syndrome (AIDS) and in other individuals from San Francisco. The AIDS-associated retroviruses (ARV) studied in detail had a type D morphology, Mg2+-dependent reverse transcriptase, and cytopathic effects on lymphocytes. The viruses can be propagated in an established adult human T cell line, HUT-78. They cross-react with antiserum to the lymphadenopathy-associated retrovirus isolated from AIDS patients in France. Antibodies to ARV were found in all 86 AIDS patients and in a high percentage of 88 other homosexual men in San Francisco. This observation indicates the widespread presence of these lymphocytopathic retroviruses and their close association with AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, J A -- Hoffman, A D -- Kramer, S M -- Landis, J A -- Shimabukuro, J M -- Oshiro, L S -- CA-34980/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 24;225(4664):840-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6206563" target="_blank"〉PubMed〈/a〉

    Description: Human fibroblasts have exhibited enhanced DNA synthesis when exposed to sinusoidally varying magnetic fields for a wide range of frequencies (15 hertz to 4 kilohertz) and amplitudes (2.3 X 10(-6) to 5.6 X 10(-4) tesla). This effect, which is at maximum during the middle of the S phase of the cell cycle, appears to be independent of the time derivative of the magnetic field, suggesting an underlying mechanism other than Faraday's law. The threshold is estimated to be between 0.5 X 10(-5) and 2.5 X 10(-5) tesla per second. These results bring into question the allegedly specific magnetic wave shapes now used in therapeutic devices for bone nonunion. The range of magnetic field amplitudes tested encompass the geomagnetic field, suggesting the possibility of mutagenic interactions directly arising from short-term changes in the earth's field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liboff, A R -- Williams, T Jr -- Strong, D M -- Wistar, R Jr -- New York, N.Y. -- Science. 1984 Feb 24;223(4638):818-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6695183" target="_blank"〉PubMed〈/a〉

    Description: The electrophysiological properties of glial cells were examined in primary culture in the presence of tetraethylammonium and Ba2+, a treatment that reduces K+ permeability of the membrane and enhances currents through voltage-dependent Ca2+ channels. Under these conditions, glial cells showed both spontaneous action potentials and action potentials evoked by the injections of current. These responses appear to represent entry of Ba2+ through Ca2+ channels because they were resistant to tetrodotoxin but were blocked by Mn2+ or Cd2+.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacVicar, B A -- New York, N.Y. -- Science. 1984 Dec 14;226(4680):1345-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095454" target="_blank"〉PubMed〈/a〉

    Description: Intraperitoneal administration of insulin to control rats and to rats with pituitary stalk transections or with lesions of the median eminence resulted in increased plasma adrenocorticotropin (ACTH) levels. The insulin-induced stimulation of ACTH release was blocked in both the control and lesioned animals by prior treatment with either the beta-adrenergic antagonist propranolol or the glucocorticoid analog dexamethasone. The direct application of insulin to primary cultures of the anterior pituitary did not evoke ACTH release or affect the maximal ability of corticotropin-releasing factor or epinephrine to stimulate ACTH secretion. The results suggest that insulin stimulates ACTH release by a mechanism in which catecholamines of peripheral origin act directly on the anterior pituitary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mezey, E -- Reisine, T D -- Brownstein, M J -- Palkovits, M -- Axelrod, J -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1085-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093262" target="_blank"〉PubMed〈/a〉

    Description: The sequence of the human epidermal growth factor (EGF) receptor shows great homology with the avian erythroblastosis virus v-erb B oncogene, raising the possibility that the receptor gene is identical to the c-erb B protooncogene. Human A431 epidermoid carcinoma cells, which have an unusually high number of EGF receptors, were examined to determine whether elevated EGF receptor levels correlate with gene amplification. Southern blots of genomic DNA's from A431 and other human cell lines were probed with either a v-erb B gene fragment or a human EGF receptor complementary DNA clone (pE7), previously isolated from an A431 complementary DNA library. When either probe was used to analyze Eco RI- or Hind III-generated DNA fragments, EGF receptor DNA sequences were amplified about 30-fold in A431. Differences in the banding pattern of A431 DNA fragments relative to normal fibroblast DNA indicate the occurrence of a rearrangement in the region of the receptor gene. Furthermore, A431 cells contain a characteristic, prominent 2.9-kilobase RNA. These results are consistent with the hypothesis that, in A431 cells, gene amplification, possibly associated with a translocation event, may result in the overproduction of EGF receptor protein or the appearance of the transformed phenotype (or both).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merlino, G T -- Xu, Y H -- Ishii, S -- Clark, A J -- Semba, K -- Toyoshima, K -- Yamamoto, T -- Pastan, I -- New York, N.Y. -- Science. 1984 Apr 27;224(4647):417-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200934" target="_blank"〉PubMed〈/a〉

    Description: Normal human colon mucosal epithelial cells were cultured in vitro and treated with the oncogenic simian DNA virus (SV40) and the chemical carcinogen azoxymethane. Both SV40 and azoxymethane altered a number of phenotypic characteristics of the normal human colon cells, including their morphology, culture longevity, growth in soft agar, substrate adherence, and peanut agglutinin binding. The SV40 transformants synthesized intranuclear T antigen. These data indicate that normal human colon mucosal cells were transformed toward the malignant phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moyer, M P -- Aust, J B -- RRO5654/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Jun 29;224(4656):1445-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6328655" target="_blank"〉PubMed〈/a〉

    Description: When human lymphocytes were cultured with [3H]thymidine, which acts as a source of low-level chronic radiation, and then exposed to 150 rad of x-rays at 5, 7, 9, or 11 hours before fixation, the yield of chromatid aberrations was less than the sum of the yields of aberrations induced by [3H]thymidine and x-rays separately. Often fewer aberrations were found after exposure to radiation from both sources than were found after exposure to x-rays alone. At the same fixation times, nonradioactive thymidine did not affect the yield of x-ray-induced aberrations. The same phenomenon occurred at earlier fixation times, after exposure to 30 or 40 rad of x-rays and [3H]thymidine. This response is analogous to the adaptive response to alkylating agents whereby prior treatment with small doses for a long period reduces the damage occurring from large doses of similar agents given for a short time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olivieri, G -- Bodycote, J -- Wolff, S -- New York, N.Y. -- Science. 1984 Feb 10;223(4636):594-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6695170" target="_blank"〉PubMed〈/a〉

    Description: Cell-free conditioned media from human T cells transformed by human T-cell leukemia-lymphoma virus (HTLV-I) were tested for the production of soluble biologically active factors, including several known lymphokines. The cell lines used were established from patients with T-cell leukemia-lymphoma and from human umbilical cord blood and bone marrow leukocytes transformed by HTLV-I in vitro. All of the cell lines liberated constitutively one or more of the 12 biological activities assayed. These included macrophage migration inhibitory factor (MIF), leukocyte migration inhibitory factor (LIF), leukocyte migration enhancing factor (MEF), macrophage activating factor (MAF), differentiation inducing factor (DIF), colony stimulating factor (CSF), eosinophil growth and maturation activity (eos. GMA), fibroblast activating factor (FAF), gamma-interferon and, in rare instances, T-cell growth factor (TCGF). Some cell lines produced interleukin 3 (IL-3), platelet-derived growth factor (PDGF), or B-cell growth factors (BCGF). Such cells should prove useful for the production of lymphokines and as sources of specific messenger RNA's for their genetic cloning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salahuddin, S Z -- Markham, P D -- Lindner, S G -- Gootenberg, J -- Popovic, M -- Hemmi, H -- Sarin, P S -- Gallo, R C -- New York, N.Y. -- Science. 1984 Feb 17;223(4637):703-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6320367" target="_blank"〉PubMed〈/a〉

    Description: On the basis of an analysis of the human and rat calcitonin genes and of a related gene, alternative RNA processing represents a developmental strategy of the brain to dictate tissue-specific patterns of polypeptide synthesis. This regulation allows the calcitonin gene to generate two messenger RNA's, one encoding the precursor of a novel neuropeptide, referred to as CGRP, which predominates in the brain, and the second encoding the precursor to the hormone calcitonin which predominates in thyroid C cells. The distribution of CGRP in the central and peripheral nervous system and in endocrine and other organ systems suggests potential functions in nociception, ingestive behavior, cardiovascular homeostasis, and mineral metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenfeld, M G -- Amara, S G -- Evans, R M -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1315-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089345" target="_blank"〉PubMed〈/a〉

Fifty percent of the receptors turned over with an unusually rapid half-life (4 hours); this was followed by a second, slower phase (32 hours). These results provide the basis for elucidating the mechanism by which neurons derived from the central nervous system control neurotransmitter receptor number, an important problem in cellular neurobiology. The findings may be of significance in the study of neurological and psychiatric disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borden, L A -- Czajkowski, C -- Chan, C Y -- Farb, D H -- New York, N.Y. -- Science. 1984 Nov 16;226(4676):857-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093257" target="_blank"〉PubMed〈/a〉

One of the major progenitors of the pol genes of such viruses gives rise to mammalian type C viruses and another gives rise to type A, B, D, and avian type C oncoviruses. Evidence of unusual patterns of homology among the env genes of mammalian type C and D oncoviruses illustrates that genetic interactions between their progenitors contributed to the evolution of oncoviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiu, I M -- Callahan, R -- Tronick, S R -- Schlom, J -- Aaronson, S A -- New York, N.Y. -- Science. 1984 Jan 27;223(4634):364-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6197754" target="_blank"〉PubMed〈/a〉

    Description: Complementary DNA clones of genes induced by platelet-derived growth factor (PDGF) in BALB/c-3T3 cells were isolated; one such clone contains a domain having nucleotide sequence homology with the third exon of c-fos. This nucleotide sequence homology is reflected in the predicted amino acid sequences of the gene products. Under low stringency conditions, the mouse v-fos gene cross-hybridizes with the PDGF-inducible complementary DNA clone. However, the messenger RNA transcripts of mouse c-fos and the new fos-related gene can be distinguished by gel electrophoresis and by S1 nuclease analysis. Expression of the authentic c-fos gene is induced by PDGF and superinduced by the combination of PDGF and cycloheximide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cochran, B H -- Zullo, J -- Verma, I M -- Stiles, C D -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1080-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093261" target="_blank"〉PubMed〈/a〉

Complete development (from sporozoite to sporulated oocyst) of a human isolate of Cryptosporidium was achieved in cultured human fetal lung cells and primary chicken kidney and porcine kidney cells.

    Description: Cultures derived from rat cerebral hemispheres were sequentially stained for acetylcholinesterase activity and for either somatostatin-like immunoreactivity or cholecystokinin-like immunoreactivity. Somatostatin-like immunoreactivity was found to coexist with acetylcholinesterase activity in individual neurons of several morphological subtypes, but cholecystokinin-like immunoreactivity and acetycholinesterase activity were never seen in the same neurons. These findings suggest a specific anatomical association, perhaps even an overlap, of the cholinergic and somatostatinergic systems in the mammalian cerebrum, and indicate that the combined deficiencies of somatostatin and cholinergic markers in Alzheimer's dementia and senile dementia of the Alzheimer type may be of pathophysiological importance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Delfs, J R -- Zhu, C H -- Dichter, M A -- HD06276/HD/NICHD NIH HHS/ -- NS00608/NS/NINDS NIH HHS/ -- NS15362/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jan 6;223(4631):61-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6140757" target="_blank"〉PubMed〈/a〉

This probe hybridized to plasmid DNA isolated from three toxigenic strains of Clostridium tetani but not to plasmid DNA from a nontoxigenic strain. These results show that the structural gene for the toxin is on the plasmid. The pCL1 plasmid from one of the toxigenic strains spontaneously deleted 22 kilobase pairs of DNA to form pCL2. Strains harboring this deleted plasmid are nontoxigenic. However, the probe mixture hybridized to pCL2, indicating that the DNA encoding the amino terminus of the toxin had not been deleted. Restriction endonuclease cleavage maps of pCL1 and pCL2 were constructed and indicate the approximate location and orientation of the structural gene for tetanus toxin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finn, C W Jr -- Silver, R P -- Habig, W H -- Hardegree, M C -- Zon, G -- Garon, C F -- New York, N.Y. -- Science. 1984 May 25;224(4651):881-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6326263" target="_blank"〉PubMed〈/a〉

    Description: Mouse tumors induced by gamma radiation are a useful model system for oncogenesis. DNA from such tumors contains an activated K-ras oncogene that can transform NIH 3T3 cells. This report describes the cloning of a fragment of the mouse K-ras oncogene containing the first exon from both a transformant in rat-2 cells and the brain of the same mouse that developed the tumor. Hybrid constructs containing one of the two pieces were made and only the plasmid including the first exon from the transformant gave rise to foci in NIH 3T3 cells. There was only a single base difference (G----A) in the exonic sequence, which changed glycine to aspartic acid in the transformant. By use of a synthetic oligonucleotide the presence of the mutation was demonstrated in the original tumor, ruling out modifications during DNA-mediated gene transfer and indicating that the alteration was present in the thymic lymphoma but absent from other nonmalignant tissue. The results are compatible with gamma radiation being a source of point mutations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guerrero, I -- Villasante, A -- Corces, V -- Pellicer, A -- CA-36327/CA/NCI NIH HHS/ -- GM-32036/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 14;225(4667):1159-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474169" target="_blank"〉PubMed〈/a〉

    Description: Recombinant DNA technology has provided a vast new source of DNA markers displaying heritable sequence variation in humans. These markers can be used in family studies to identify the chromosomal location of defective genes causing nervous system disorders. The discovery of a DNA marker linked to Huntington's disease has opened new avenues of research into this disorder and may ultimately permit cloning and characterization of the defective gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gusella, J F -- Tanzi, R E -- Anderson, M A -- Hobbs, W -- Gibbons, K -- Raschtchian, R -- Gilliam, T C -- Wallace, M R -- Wexler, N S -- Conneally, P M -- NS16367/NS/NINDS NIH HHS/ -- NS20012/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1320-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089346" target="_blank"〉PubMed〈/a〉

    Description: Physiological properties of acetylcholine receptors on muscle cells at very early stages of ontogeny were compared with those of cells at later stages. Two changes were observed that contributed to an overall shortening of the mean open time of single-channels. First, there was a shift in the relative proportions of two receptor types with different conductances and mean open times, such that the contribution of receptors with large conductance and short open time increased as development proceeded. Second, there was a sharp reduction in the mean open time of channels having small conductance, with no similar change in channels having large conductance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leonard, R J -- Nakajima, S -- Nakajima, Y -- Takahashi, T -- NS08601/NS/NINDS NIH HHS/ -- T32-GM-07211/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):55-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474189" target="_blank"〉PubMed〈/a〉

    Description: A replication-defective, acute transforming retrovirus (murine sarcoma virus 3611) was isolated from mouse and molecularly cloned. The nucleotide sequence of 1.5 kilobases encompassing the transforming gene (v-raf) was determined. This sequence, which predicts the amino acid sequence of a gag-raf fusion protein, terminates 180 nucleotides from the 3' end of the acquired cellular sequence. Comparison of the predicted amino acid sequence of v-raf with the predicted amino acid sequences of other oncogenes reveals significant homologies to the src family of oncogenes. There is a lack of homology within the sequence of the tyrosine acceptor domain described for the phosphotyrosine kinase members of the src family of transforming proteins. Phylogenetic arrangement of this family of oncogenes suggests that tyrosine-specific phosphorylation may be a recently acquired activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mark, G E -- Rapp, U R -- New York, N.Y. -- Science. 1984 Apr 20;224(4646):285-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6324342" target="_blank"〉PubMed〈/a〉

    Description: Stimulation of cultures of murine bone-marrow cells with specific macrophage growth factor (colony-stimulating factor I) resulted in the production of type I interferon. Neutralization of this endogenous interferon by antiserum directed against interferons alpha and beta resulted in a significant enhancement of mononuclear phagocyte proliferation from committed marrow precursors. The effect of the antiserum was lost in cultures depleted of adherent cells, an indication that an adherent regulatory cell (or cells) in the marrow limits mononuclear phagocyte proliferation by producing antiproliferative interferon in response to high levels of specific growth factor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, R N -- Larsen, H S -- Horohov, D W -- Rouse, B T -- AI-14981/AI/NIAID NIH HHS/ -- AI-18960/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Jan 13;223(4632):178-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6606850" target="_blank"〉PubMed〈/a〉

    Description: Mutants of Sindbis virus were selected for rapid growth in baby hamster kidney (BHK) cell cultures and screened for attenuation of virulence in suckling mice. Comparisons among independently isolated virulent and attenuated strains, as well as a classical reversion analysis, showed that accelerated penetration of BHK cells was correlated with attenuation in vivo. Both phenotypic changes resulted from a reorganization of virion structure as detected by monoclonal antibodies. These results suggest that mutants selected for rapid growth in cell culture may be useful as attenuated vaccines and for studies of the molecular basis of virus pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olmsted, R A -- Baric, R S -- Sawyer, B A -- Johnston, R E -- AI19433/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Jul 27;225(4660):424-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6204381" target="_blank"〉PubMed〈/a〉

    Description: Cultured fibroblasts obtained from patients with tissue resistance to 1,25-dihydroxyvitamin D3 (vitamin D3--dependent rickets, type II) contain normal, low, or undetectable concentrations of this hormone's receptor protein as measured by a ligand-binding assay. Extracts from these cells were evaluated for receptors by immunoassay with a recently developed monoclonal antibody to the chick receptor. The results show that a protein sedimenting at 3.7S and recognizable by the antibody exists in comparable concentrations in cells from both normal and resistant patients, irrespective of the hormone-binding abnormalities of the cells. This implies that deficiencies in hormone binding associated with inherited tissue resistance to 1,25-dihydroxyvitamin D3 probably arise from structural variations in the receptor molecule and not from defective receptor synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pike, J W -- Dokoh, S -- Haussler, M R -- Liberman, U A -- Marx, S J -- Eil, C -- AM 15781/AM/NIADDK NIH HHS/ -- AM 32313/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1984 May 25;224(4651):879-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6326262" target="_blank"〉PubMed〈/a〉

    Description: Two regions of the gene for the human T-cell leukemia virus subgroup I (HTLV-I) envelope were expressed in Escherichia coli by use of the vector pJLA16. One corresponds to the carboxyl terminal region of the major envelope protein p46, and the other corresponds to the transmembrane protein p21E. Reactivity of the expressed protein with human serum was tested by the Western blot procedure. Each of 11 sera tested that had been shown to contain antibodies to HTLV-I or HTLV-II by an enzyme-linked immunosorbent assay recognized the bacterially synthesized envelope proteins. There was no reaction detected when 17 control sera were tested. This system will be useful for large-scale seroepidemiological surveys for HTLV-I and related human retroviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Samuel, K P -- Lautenberger, J A -- Jorcyk, C L -- Josephs, S -- Wong-Staal, F -- Papas, T S -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1094-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6208612" target="_blank"〉PubMed〈/a〉

    Description: Multicellular spheroids were grown from mixtures of rat brain tumor cells sensitive (9L) and resistant (R3) to 1,3-bis(2-chloroethyl)-1-nitrosourea. Percentages of each cell subpopulation in these spheroids were estimated with the sister chromatid exchange assay and were found to be approximately the same as those used to initiate spheroids. Spheroids grown from 9L cells alone had a higher growth rate than spheroids grown from R3 cells alone. However, the growth rate of mixed-cell spheroids was essentially the same as that of pure 9L spheroids and was independent of the percentages of R3 cells in mixed-cell spheroids. The sensitivity of 9L cells in mixed-cell spheroids treated with 1,3-bis(2-chloroethyl)-1-nitrosourea, estimated by changes in the number of sister chromatid exchanges per metaphase induced by treatment, decreased as the percentage of R3 cells increased. These effects are probably the result of an interaction between the two cell subpopulations held in three-dimensional contact, a situation similar to that in tumors in situ. The results suggest why one cell subpopulation of tumors does not become dominant during growth and indicate that interactions between cell subpopulations can influence the sensitivity of one subpopulation to 1,3-bis(2-chloroethyl)-1-nitrosourea.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tofilon, P J -- Buckley, N -- Deen, D F -- CA-09215/CA/NCI NIH HHS/ -- CA-31867/CA/NCI NIH HHS/ -- CA-31868/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Nov 16;226(4676):862-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6494917" target="_blank"〉PubMed〈/a〉

    Description: The preferred binding sites of echinomycin on DNA can be determined by a method called "footprinting." A 32P end-labeled restriction fragment from pBR322 DNA is protected by binding to echinomycin, and cleaved by a synthetic DNA cleaving reagent, methidiumpropyl--EDTA . Fe(II); the DNA cleavage products are then subjected to high-resolution gel analyses. This method reveals that echinomycin has a binding site size of four base pairs. The strong binding sites for echinomycin contain the central two-base-pair sequence 5'-CG-3'. From an analysis of 15 echinomycin sites on 210 base pairs of DNA, key recognition elements for echinomycin are contained in the sequences (5'-3') ACGT and TCGT (A, adenine; C, cytosine; G, guanine; T, thymine).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Dyke, M M -- Dervan, P B -- GM-07616/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 14;225(4667):1122-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089341" target="_blank"〉PubMed〈/a〉

One family consists of full-length (8.8 kilobases) proviral structures, with typical long terminal repeates (LTR's). The other family consists of structures, which contain only 4.1 kilobases of gag-pol sequences, bounded by a tandem array of imperfect repeats 72 to 76 base pairs in length.

As a consequence of this treatment, oncogenes capable of transforming NIH/3T3 cells became activated in each of five independently established clonal guinea pig cell lines. Molecular characterization of representative NIH/3T3 transformants revealed that the same oncogene was present in each of the cell lines tested. Moreover, detection of this transforming gene paralleled the acquisition of tumorigenic properties by these neoplastic cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sukumar, S -- Pulciani, S -- Doniger, J -- DiPaolo, J A -- Evans, C H -- Zbar, B -- Barbacid, M -- New York, N.Y. -- Science. 1984 Mar 16;223(4641):1197-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6322298" target="_blank"〉PubMed〈/a〉

    Description: The M protein is the antigen on the surface of group A streptococci that allows these bacteria to resist phagocytosis. DNA encoding the M12 protein was cloned into Escherichia coli and used as an isotopically labeled hybridization probe to compare genomic DNA's isolated from M+ and M- isogenic cultures in an effort to elucidate the genetic basis of this variation. DNA's from two spontaneous, independent M- variants contained small (approximately 50 base pairs) deletions which were mapped to identical restriction fragments within or adjacent to the M protein coding sequence. Taken together with the pleiotropic nature of these deletions, this suggests that they define a regulatory switch.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spanier, J G -- Jones, S J -- Cleary, P -- 5T32HLI07114/HL/NHLBI NIH HHS/ -- AI16722/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):935-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089334" target="_blank"〉PubMed〈/a〉

    Description: The effect of serum on the rate of substrate oxidation by dissociated brain cells in vitro was examined. At a serum protein concentration of approximately 0.55 milligram per milliliter, oxidation of [6-14C]glucose to 14CO2 was decreased more than 50 percent. Oxidation of [3-14C]-3-hydroxybutyrate and [U-14C]glutamine was decreased much less. Serum from cows, rats, horses, and humans produced similar effects, as did serum from young and old animals and from both sexes. The effect on [6-14C]glucose oxidation was proportional to serum protein concentration, and significant inhibitory activity was obtained with dialyzed serum. Heating (80 degrees C for 10 minutes) significantly reduced the inhibitory activity. These results suggest the presence of a factor in serum that can preferentially decrease glucose oxidation. Such a factor would have profound implications for metabolic regulation in vivo and for studies of cells in vitro in which serum is included in the growth medium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tildon, J T -- Stevenson, J H -- New York, N.Y. -- Science. 1984 May 25;224(4651):903-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6719124" target="_blank"〉PubMed〈/a〉

    Description: From an acute B-cell leukemia cell line, a DNA probe was obtained that was specific for chromosome 18 and flanked the heavy chain joining region of the immunoglobulin heavy chain locus on chromosome 14. This probe detected rearrangement of the homologous DNA segment in the leukemic cells and in follicular lymphoma cells with the t(14:18) chromosome translocation but not in other neoplastic or normal B or T cells. The probe appears to identify bcl-2, a gene locus on chromosome 18 (band q21) that is unrelated to known oncogenes and may be important in the pathogenesis of B-cell neoplasms with this translocation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsujimoto, Y -- Finger, L R -- Yunis, J -- Nowell, P C -- Croce, C M -- CA15822/CA/NCI NIH HHS/ -- CA16685/CA/NCI NIH HHS/ -- CA20034/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1097-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093263" target="_blank"〉PubMed〈/a〉

    Description: Breaks were observed at 51 sites in homologous chromosomes in lymphocytes from ten humans and two great apes when cells were deprived of thymidine. The incidence of breaks was enhanced by caffeine, a substance that inhibits DNA repair in replicating cells. The locations of 20 sites were correlated with breakpoints that have been related to human malignancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yunis, J J -- Soreng, A L -- New York, N.Y. -- Science. 1984 Dec 7;226(4679):1199-204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6239375" target="_blank"〉PubMed〈/a〉

    Description: Sequential development of Leishmania promastigotes from a noninfective to an infective stage was demonstrated for promastigotes growing in culture and in the sandfly vector. The generation of an infective stage was found to be growth cycle-dependent and restricted to nondividing organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sacks, D L -- Perkins, P V -- New York, N.Y. -- Science. 1984 Mar 30;223(4643):1417-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6701528" target="_blank"〉PubMed〈/a〉

    Description: A small virus resembling parvoviruses in its morphological and physicochemical properties was derived from synovial tissue of a patient with severe rheumatoid arthritis. This virus, designated RA-1, elicits a syndrome in neonatal mice that includes neurological disturbances, permanent crippling of limbs, dwarfism, alopecia, blepharitis, "masking," and a rigid curvature of the thoracic spine. Polyclonal antibodies against RA-1 display high virus neutralizing activity and in immunoassays detect reactive antigen in synovial cells from different rheumatoid arthritis patients but not persons with osteoarthritis. Putative parvoviruses isolated from several other rheumatoid arthritis patients are only weakly pathogenic for newborn mice but can generate RA-1 virus-specific antigens in tissues of these animals. It has not been established that RA-1 and existing parvoviruses of mammalian species are related.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simpson, R W -- McGinty, L -- Simon, L -- Smith, C A -- Godzeski, C W -- Boyd, R J -- AI-14359/AI/NIAID NIH HHS/ -- AI-17262/AI/NIAID NIH HHS/ -- AM-15796/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1984 Mar 30;223(4643):1425-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6701529" target="_blank"〉PubMed〈/a〉
