    Human sleep: its duration and organization depend on its circadian phase (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-12-12
    Description: Two- to threefold variations in sleep length were observed in 12 subjects living on self-selected schedules in an environment free of time cues. The duration of polygraphically recorded sleep episodes was highly correlated with the circadian phase of the body temperature rhythm at bedtime and not with the length of prior wakefulness. Furthermore, the rate of REM (rapid eye movement) sleep accumulation , REM latency, bedtime selection, and self-rated alertness assessments were also correlated with the body temperature rhythm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Czeisler, C A -- Weitzman, E d -- Moore-Ede, M C -- Zimmerman, J C -- Knauer, R S -- AG-00792/AG/NIA NIH HHS/ -- GM-07365/GM/NIGMS NIH HHS/ -- MH-28460/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 12;210(4475):1264-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434029" target="_blank"〉PubMed〈/a〉

    Collagen: molecular diversity in the body's protein scaffold (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-21
    Description: Intensive research in the last decade has revealed a wealth of detail on the mechanism of biosynthesis, molecular structure, and covalent cross-linking of collagen. Tissues of higher animals express a family of at least five genetically distinct types of collagen molecule, each apparently tailored for different construction work outside the cell. Within each genetic type of collagen, further chemical heterogeneity is also evident; the variations in hydroxylation, glycosylation, and cross-linking are dependent, for example, on tissue type, age, and hormonal status. The functional significance of collagen's molecular diversity and its control by different cells and tissues are not yet well understood but abnormalities of collagen in many human diseases keep this protein a focal molecule of medical research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eyre, D R -- New York, N.Y. -- Science. 1980 Mar 21;207(4437):1315-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355290" target="_blank"〉PubMed〈/a〉

    Distribution of active gene sequences: a subset associated with tightly bound chromosomal proteins (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-08
    Description: The distribution of active polyadenylate-messenger RNA sequences in fractionated chicken liver chromatin was examined. A portion of these active gene sequences is concentrated in a DNA fraction retained by tightly bound nonhistone chromosomal proteins, while the nonretained DNA fraction is substantially depleted of a portion of these sequences. These findings suggest that the tightly bound nonhistones are physically associated with a subset of active gene sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gates, D M -- Bekhor, I -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):661-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352280" target="_blank"〉PubMed〈/a〉

    Comparison of the nucleic acid sequence of anglerfish and mammalian insulin mRNA's from cloned cDNA's (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-12-19
    Description: Anglerfish (Lophius americanus) insulin complementary DNA was cloned in bacterial plasmids, and its sequence was determined. Fish insulin messenger RNA is larger (1.5 times) than the messenger RNA encoding mammalian (rat and human) insulin, in part because of a larger C peptide (an additional six amino acids or 18 nucleotides in length) but mainly because of increases in the 5' and 3' untranslated regions. Comparison of the fish, rat, and human insulin messenger RNA (from the complementary DNA) reveals that, in addition to the regions coding for the A and B peptides, sequence conservation is limited to a segment within the 5' untranslated region which may be involved in ribosomal binding, two small segments of the signal peptide, and two stretches of sequence in the 3' untranslated region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hobart, P M -- Shen, L P -- Crawford, R -- Pictet, R L -- Rutter, W J -- AM 21344/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 19;210(4476):1360-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7001633" target="_blank"〉PubMed〈/a〉

    High-molecular-weight immunoreactive beta-endorphin in extracts of human placenta is a fragment of immunoglobulin G (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-11
    Description: A high-molecular-weight protein with beta-endorphin- and adrenocorticotropin-immunoreactivities was isolated from extracts of human placenta after several purification steps, including immunoadsorption with a well-characterized antiserum raised to beta-endorphin. This protein was identified as the heavy chain of the human immunoglobulin class IgG1. These results have led to the recognition of homologies in the amino acid sequences of these physiologically unrelated molecules. They also suggest caution in accepting immunological competence as the sole criterion of the chemical identity of a ligand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Julliard, J H -- Shibasaki, T -- Ling, N -- Guillemin, R -- New York, N.Y. -- Science. 1980 Apr 11;208(4440):183-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6244620" target="_blank"〉PubMed〈/a〉

    Buprenorphine suppresses heroin use by heroin addicts (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-08
    Description: Heroin-dependent men were given buprenorphine (a partial opiate agonist-antagonist) or a placebo under duoble-blind conditions on a clinical research ward where they could acquire heroin (21 to 40.5 milligrams per day, intravenously). Buprenorphine significantly (P less than .001) suppressed the self-administration of heroin over 10 days. Control subjects took between 93 and 100 percent of the available heroin. The effects of buprenorphine were dose-dependent; a dose of 8 milligrams per day reduced heroin use by 69 to 98 percent; a dose of 4 milligrams per day reduced heroin use by 45 percent. Termination of buprenorphie maintenance did not result in opiate withdrawal signs or symptoms. The subjects liked buprenorphine and indicated that it was preferable to methadone or naltrexone. Buprenorphine should be a safe and effective new pharmacotherapy for heroin dependence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mello, N K -- Mendelson, J H -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):657-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352279" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-05-30
    Description: Cloned repetitive DNA sequences were used to determine the number of homologous RNA transcripts in the eggs of two sea urchin species, Strongylocentrotus purpuratus and S. franciscanus. The eggs of these species contain different amounts of RNA, and their genomes contain different numbers of copies of the cloned repeats. The specific pattern of repetitive sequence representation in the two egg RNA's is nonetheless quantitatively similar. The evolutionary conservation of this pattern suggests the functional importance of repeat sequence expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, G P -- Costantini, F D -- Posakony, J W -- Davidson, E H -- Britten, R J -- New York, N.Y. -- Science. 1980 May 30;208(4447):1046-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6154974" target="_blank"〉PubMed〈/a〉

    Properties of a normal mouse cell DNA sequence (sarc) homologous to the src sequence of Moloney sarcoma virus (1980)

    Details
    Publication Date: 1980-03-14
    Description: A 15.0-kilobase (kb) Eco RI DNA fragment from normal mouse Balb/c genomic DNA that contains sequences (sarc) homologous to the acquired cell sequences (src) of Moloney sarcoma virus (MSV) has been cloned in phage lambda. The sarc region (1.2 to 1.3 kb) of the 15.0-kb cell fragment is indistinguishable from the src region of two isolates of MSV as judged by heteroduplex and restriction endonuclease analyses. The cellular sequences flanking sarc show no homology to other MSV sequences. Whereas cloned subgenomic portions of MSV that contain src transformed NIH-3T3 cells in vitro, the cloned sarc fragment is inactive.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oskarsson, M -- McClements, W L -- Blair, D G -- Maizel, J V -- Vande Woude, G F -- New York, N.Y. -- Science. 1980 Mar 14;207(4436):1222-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243788" target="_blank"〉PubMed〈/a〉

    Genes for growth hormone, chorionic somatommammotropin, and growth hormones-like gene on chromosome 17 in humans (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-11
    Description: The human genes for growth hormone (GH), chorionic somatomammotropin (CSH), and a third growth hormone-like gene (GHL) have been located on chromosome 17 in humans. DNA fragments of 2.6, 2.8, and 9.5 kilobase pairs containing GH, CSH, and GHL, respectively, were identified in human genomic DNA, and a 7.5-kilobase DNA fragment related to growth hormone DNA sequences was found in mouse cells. In somatic hybrids of human and mouse cells containing reduced numbers of human chromosomes, but a normal complement of mouse chromosomes, the mouse, 7.5-kolobase DNA fragment was always present, whereas the 2.6-, 2.8-, and 9.5-kilobase human fragments were present only when human chromosome 17 was also present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owerbach, D -- Rutter, W J -- Martial, J A -- Baxter, J D -- Shows, T B -- New York, N.Y. -- Science. 1980 Jul 11;209(4453):289-92.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384802" target="_blank"〉PubMed〈/a〉

    The origins of gene instability in yeast (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Two unstable mutations at the his4 locus of yeast are due to the insertion of the transposable elements Ty912 and Ty917 into the his4 regulatory region. The two transposons are related, one being derived from the other by a substitution of 4000 base pairs of DNA. Element Ty912 includes identical terminal repeats, whereas the terminal repeats of Ty917 are not identical. Transposition of Ty912 or Ty917 generates 5-base-pair duplications of the target DNA at either end of the element. Expression and reversion of a his4 gene containing Ty912 or Ty917 is controlled by three unlinked regulatory genes. The properties of these regulatory genes are similar to those described for the controlling elements in maize.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roeder, G S -- Farabaugh, P J -- Chaleff, D T -- Fink, G R -- CA23441/CA/NCI NIH HHS/ -- GM07617/GM/NIGMS NIH HHS/ -- GM15408/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1375-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251544" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Many eukaryotic genes contain intevening sequences, segments of DNA that interrupt the continuity of the gene. They are removed from RNA transcripts of the gene by a process known as splicing. The intervening sequence in a yeast tyrosine transfer RNA (tRNA Tyr) suppressor gene was deleted in order to test its role in the expression of the gene. The altered gene and its parent were introduced into yeast by transformation. Both genes exhibited suppressor function, showing that the intervening sequence is not absolutely essential for the expression of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallace, R B -- Johnson, P F -- Tanaka, S -- Schold, M -- Itakura, K -- Abelson, J -- CA10984/CA/NCI NIH HHS/ -- GM 26391/GM/NIGMS NIH HHS/ -- GM 35658/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1396-400.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6997991" target="_blank"〉PubMed〈/a〉

    Description: Teacher interactions with hyperactive and comparison boys were observed during classroom activities. A double-blind, methylphenidate-placebo cross-over design was used within the hyperactive group. With no knowledge of any child's diagnosis or drug status, the teacher was more intense and controlling toward hyperactive boys taking placebo than toward either medicated hyperactive boys or comparison boys; her behavior did not differ toward the latter two groups. Discussion focused on the need to consider the broad social ramifications of pharmacologic treatment programs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whalen, C K -- Henker, B -- Dotemoto, S -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1280-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375940" target="_blank"〉PubMed〈/a〉

    Description: The ability to see spatial structures of a wide range of sizes was measured for two groups of observers (mean ages, 18 and 73 years). All observers had good visual acuity. Although older and younger observers did not differ in ability to see targets with fine structure (high spatial frequencies), older observers were only one-third as sensitive to targets with coarse structure (low spatial frequencies) as were younger observers or to changes in criterion. Older observers were also less able than younger observers to see moving targets. The reduced sensitivity of the older observers may adversely affect routine perceptual activities, such as face recognition and visually guided postural behavior, that depend upon low spatial frequencies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sekuler, R -- Hutman, L P -- Owsley, C J -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1255-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403884" target="_blank"〉PubMed〈/a〉

    Description: Moderate chronic malnutrition has only a minor effect on fecundity (reproductive capacity), and the resulting effect on fertility (actural reproduction) is very small. Among the fecundity components examined here in noncontracepting populations, age at menarche and the duration of lactational amenorrhea appear to be the ones most affected by malnutrition. But from neither of those effects can a difference in fertility of more than a few percent be expected between poorly and well-nourished women in developing countries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bongaarts, J -- New York, N.Y. -- Science. 1980 May 9;208(4444):564-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367878" target="_blank"〉PubMed〈/a〉

Biological offspring were found to show nonrandom distributions of right- and non-right-handedness as a function of parental handedness; these distributions were consistent with the results fo previous family studies. In contrast, the handedness distribution of adopted children as a function of parental handedness was essentially random.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carter-Saltzman, L -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1263-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403887" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1980-02-22
    Description: Extracts of fresh-frozen bovine neurohypophysis were purified by chromatographic techniques to isolate and characterize the components that produce natriuresis in nondiuretic dogs. Two compounds with natiuretic properties similar to those of synthetic arginine vasopressin accounted for most of the natriuretic activity and appeared to be the prevalent vasopressin-like molecules in the extract. These peptides were Ala-Gly-[Arg8]-vasopressin and Val-Asp-[Arg8]-vasopressin; the natriuretic potency of each appeared to be similar to synthetic arginine vasopressin and could be observed with doses in the range of 50 picomoles. In the dog the most conspicuous difference between synthetic arginine vasopressin and the new vasopressin peptides was the smaller pressor responses to natriuretic doses of the new compounds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gitelman, H J -- Klapper, D G -- Alderman, F R -- Blythe, W B -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):893-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355269" target="_blank"〉PubMed〈/a〉

    Phase variation: evolution of a controlling element (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Phase variation in bacteria is regulated by homologous recombination at a specific DNA site. This recombinational event causes the inversion of a 970-base-pair DNA sequence that includes the promoter necessary for transcription of a flagellar gene. The invertible segment is flanked by two sites that are necessary for the inversion and contains a gene (hin) whose product mediates the inversion event. The hin gene shows extensive homology with the TnpR gene carried on the Tn3 transposon. It is also homologous with the gin gene carried on bacteriophage mu. These relationships suggest that the phase variation system may have evolved by the association of a transposon with a resident gene and the subsequent specialization of these elements to regulate flagellar antigen expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simon, M -- Zieg, J -- Silverman, M -- Mandel, G -- Doolittle, R -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1370-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251543" target="_blank"〉PubMed〈/a〉

This difference was absent after double-blind administration of caffeine citrate or placebo. In a discriminative reaction time test, caffeine treatment improved performance. Among subjects receiving placebo, anxiety was highly correlated with prior caffeine use, suggesting that even a brief abstinence may produce anxiety in the regular user.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, B C -- Lincoln, C A -- Pearce, N W -- Reeb, R -- Vaida, C -- AA 03513/AA/NIAAA NIH HHS/ -- HD 05958/HD/NICHD NIH HHS/ -- NS 11618/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 26;209(4464):1547-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7433978" target="_blank"〉PubMed〈/a〉

    Description: Four recombinant lambda phages containing nucleotide sequences complementary to a cloned human preproinsulin DNA probe have been isolated from human DNA. Restriction analyses in conjunction with Southern hybridizations reveal two types of gene sequences. One isolate of each type was subjected to complete nucleotide sequence determination. The sequences contain the entire preproinsulin messenger RNA region, two intervening sequence. 260 nucleotides upstream from the messenger RNA capping site, and 35 nucleotides beyond the polyadenylate attachment site. Our results strongly suggest that these two gene types are allelic variants of a single insulin gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ullrich, A -- Dull, T J -- Gray, A -- Brosius, J -- Sures, I -- New York, N.Y. -- Science. 1980 Aug 1;209(4456):612-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6248962" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-02-08
    Description: When young adults detected auditory stimuli at split-second intervals, different components of the event-related brain potentials showed markedly different speeds of recovery. The P3 component (latency 300 to 350 milliseconds) was fully recovered at intervals of less than 1.0 second, while the N1--P2 components (latencies 100 to 180 milliseconds) were markedly attenuated with stimulus repetition even at longer interstimulus intervals. Thus, the N1--P2 recovers much more slowly than a subject's ability to evaluate signals, whereas the P3 appears to be generated at the same high rates as the decision processes with which it is associated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woods, D L -- Hillyard, S A -- Courchesne, E -- Galambos, R -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):655-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352278" target="_blank"〉PubMed〈/a〉

    DNA sequences mediating class switching in alpha-immunoglobulins (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Immunoglobulin class switching involves specific DNA rearrangements of the gene segments coding for heavy chain constant regions (CH) during B lymphocyte differentiation. In two different cases of C mu to C alpha switching examined here (T15 and M603) and one taken from the literature (MC101), three different sites on the 5' side of C mu and three different sites on the 5' side of C alpha are joined together in the process of CH switching. The sequences surrounding the three germ-line C alpha sites of recombination are highly conserved blocks of 30 nucleotides that may serve as recognition sequences for CH switching to the C alpha gene. This putative recognition sequence is repeated 17 times in approximately 1400 nucleotides of the germ-line Calpha 5' flanking sequence. The lack of homology between this C alpha sequence and sequences reported for the C gamma 1 and C gamma 2b switch sites suggests that heavy chain switching is mediated by class-specific recognition sequences and, presumably, class-specific regulatory mechanisms. In addition, it appears that in one example (MC101) CH switching progressed from C mu to C alpha to C gamma 1. This switching pathway may present difficulties for the simple deletional model of CH switching.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M M -- Kim, S K -- Hood, L E -- AI 09072/AI/NIAID NIH HHS/ -- GM 07616/GM/NIGMS NIH HHS/ -- PCM76-81546/PC/NCI NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1360-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6774415" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1980-12-05
    Description: In a patient with gyrate atrophy of the choroid and retina, an arginine-deficient diet has reduced plasma ornithine concentration fivefold during the past 20 months. Subjective improvement in her visual function was noted approximately 15 months after institution of her diet. This has been documented by improvements in the electroretinogram, dark-adaptation, and color vision. The improvement involves rod and, to a lesser extent, cone function. The results, although preliminary and limited to a single patient, suggest that reduction of plasma ornithine with a low arginine diet is beneficial in this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaiser-Kupfer, M I -- de Monasterio, F M -- Valle, D -- Walser, M -- Brusilow, S -- EY-02948/EY/NEI NIH HHS/ -- RR-52/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 5;210(4474):1128-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444439" target="_blank"〉PubMed〈/a〉

This observation supports recent reports of elevated concentrations of norepinephrine in specific brain areas adjacent to the cerebral ventricles of paranoid schizophrenic patients. Overflow of the amine from periventricular regions into the cerebrospinal fluid may reflect abnormally high release or diminished enzymatic destruction of norepinephrine in patients with schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lake, C R -- Sternberg, D E -- van Kammen, D P -- Ballenger, J C -- Ziegler, M G -- Post, R M -- Kopin, I J -- Bunney, W E -- New York, N.Y. -- Science. 1980 Jan 18;207(4428):331-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7350667" target="_blank"〉PubMed〈/a〉

    Estimating cancer risks from low doses of ionizing radiation (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-12
    Description: Disagreements about the somatic risks from low doses of ionizing radiation stem from two difficulties fundamental to the logic of inference from observational data. First, precise direct estimation of small risks requires impracticably large samples. Second, precise estimates of low-dose risks based largely on high-dose data, for which the sample size requirements are more easily satisfied, must depend heavily on assumptions about the shape of the dose-response curve, even when only a few of the parameters of the theoretical form of the curve are unknown.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Land, C E -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1197-203.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403879" target="_blank"〉PubMed〈/a〉

    Structure and in vitro transcription of human globin genes (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: The alpha-like and beta-like subunits of human hemoglobin are encoded by a small family of genes that are differentially expressed during development. Through the use of molecular cloning procedures, each member of this gene family has been isolated and extensively characterized. Although the alpha-like and beta-like globin genes are located on different chromosomes, both sets of genes are arranged in closely linked clusters. In both clusters, each of the genes is transcribed from the same DNA strand, and the genes are arranged in the order of their expressions during development. Structural comparisons of immediately adjacent genes within each cluster have provided evidence for the occurrence of gene duplication and correction during evolution and have led to the discovery of pseudogenes, genes that have acquired numerous mutations that prevent their normal expression. Recently, in vivo and in vitro systems for studying the expression of cloned eukaryotic genes have been developed as a means of identifying DNA sequences that are necessary for normal gene function. This article describes the application of an in vitro transcription procedure to the study of human globin gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Proudfoot, N J -- Shander, M H -- Manley, J L -- Gefter, M L -- Maniatis, T -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1329-36.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6158093" target="_blank"〉PubMed〈/a〉

    At least three human type alpha interferons: structure of alpha 2 (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: The sequence of a human leukocyte-derived complementary DNA (cDNA), Hif-2h, which directs the formation in Escherichia coli of a polypeptide, IFN-alpha 1, with interferon (IFN) activity has been described. A second IFN cDNA, Hif-SN206, which also elicits synthesis of a biologically active IFN, IFN-alpha 2, is described in this article. Whereas IFN-alpha 2 is twice as active on human as on bovine cells, IFN-alpha 1 is 10 to 20 times more active on bovine than on human cells. As deduced from the cDNA's, the messenger RNA's for the two IFN's differ in length and in 20 percent of the nucleotides; the mature IFN polypeptides differ in 17 percent of the amino acids. Both IFN-alpha 1 and IFN-alpha 2 differ from the lymphoblastoid IFN described by others. Therefore, at least three different IFN-alpha genes are expressed in man; studies on genomic DNA reveal the presence of at least eight IFN-related genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streuli, M -- Nagata, S -- Weissmann, C -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1343-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6158094" target="_blank"〉PubMed〈/a〉

    Description: In vitro genetic techniques were used to study the sequence requirements for the initiation of specific transcription. Deletion mutants were constructed around the putative promoter of the adenovirus-2 major late and chicken conalbumin genes. Specific transcription in vitro by RNA polymerase B together with a HeLa cell cytoplasmic extract was used as the test for promoter function. With this approach sequences which are essential for the initiation of specific transcription in vitro, were shown to be located between 12 and 32 base pairs upstream from the 5' end of these genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corden, J -- Wasylyk, B -- Buchwalder, A -- Sassone-Corsi, P -- Kedinger, C -- Chambon, P -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1406-14.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251548" target="_blank"〉PubMed〈/a〉

    Mouse globin system: a functional and evolutionary analysis (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Structural and functional analysis of the mouse alpha-globin and beta-globin genes reveals that the globin genes are encoded in discontinous bits of coding information and that each gene locus is much more complex than was originally supposed. Each seems to consist of an array of several authentic genes as well as several apparently inactive pseudogenes. Comparison of the sequences of some of these genes to one another indicates that chromosomal DNA is a dynamic structure. Flanking and intervening sequences change in two ways: quickly, by duplication and extensive insertions and deletions, and slowly, by point mutation. Active coding sequences are usually limited to the slower mode of evolution. In addition to identifying fast and slow modes of evolution, it has also been possible to test the function of several signals that surround these genes and to identify those that appear to play a role in gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leder, P -- Hansen, J N -- Konkel, D -- Leder, A -- Nishioka, Y -- Talkington, C -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1336-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7414319" target="_blank"〉PubMed〈/a〉

    Acetylcholine receptor: complex of homologous subunits (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-27
    Description: The acetylcholine receptor from the electric ray Torpedo californica is composed of five subunits; two are identical and the other three are structurally related to them. Microsequence analysis of the four polypeptides demonstrates amino acid homology among the subunits. Further sequence analysis of both membrane-bound and Triton-solubilized, chromatographically purified receptor gave the stoichiometry of the four subunits (40,000:50,000:60,000:65,000 daltons) as 2:1:1:1, indicating that this protein is a pentameric complex with a molecular weight of 255,000 daltons. Genealogical analysis suggests that divergence from a common ancestral gene occurred early in the evolution of the receptor. This shared ancestry argues that each of the four subunits plays a functional role in the receptor's physiological action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raftery, M A -- Hunkapiller, M W -- Strader, C D -- Hood, L E -- New York, N.Y. -- Science. 1980 Jun 27;208(4451):1454-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384786" target="_blank"〉PubMed〈/a〉

    Nucleotide sequence of human preproinsulin complementary DNA (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-04
    Description: Recombinant bacterial plasmids that contain DNA complementary to human preproinsulin messenger RNA have been constructed. One clone contains the entire preproinsulin coding region, as well as the 3' untranslated region of the messenger RNA and eight nucleotides of the 5' untranslated region. Additional sequence information for the 5' untranslated region was obtained with the use of insulinoma messenger RNA in conjunction with specific primers from the cloned DNA for enzymatic chain termination sequence analysis. The results confirm the amino acid sequence of human proinsulin previously determined, and predict the amino acid sequence of the human preproinsulin signal peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sures, I -- Goeddel, D V -- Gray, A -- Ullrich, A -- New York, N.Y. -- Science. 1980 Apr 4;208(4439):57-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6927840" target="_blank"〉PubMed〈/a〉

    Mouse immunoglobulin D: messenger RNA and genomic DNA sequences (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: The molecular structure of a mouse immunoglobulin D from a plasmacytoma tumor and that of the normal mouse gene coding for immunoglobulin D are presented. The DNA sequence results indicate an unusual structure for the tumor delta chain in two respects: (i) Only two constant (C) region domains, termed C delta 1 and C delta 3 by homology considerations, are found; the two domains are separated by an unusual hinge region C delta H that lacks cysteine residues and thus cannot provide the covalent cross-links between heavy chains typically seen in immunoglobulins. The two domains and hinge are all coded on separate exons. (ii) At the carboxyl end of the delta chain there is a stretch of 26 amino acids that is coded from an exon located 2750 to 4600 base pairs downstream from the rest of the gene. Analogy with immunoglobulin M suggests that this distally coded segment C delta DC may have a membrane-binding function; however, it is only moderately hydrophobic. A fifth potential exon (C delta AC), located adjacent to the 3' (carboxyl) end of C delta 3, could code for a stretch of 49 amino acids. The tumor's expression of the delta gene may be aberrant, but the simplest interpretation would be that this tumor expresses one of the several biologically significant forms of the delta chain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tucker, P W -- Liu, C P -- Mushinski, J F -- Blattner, F R -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1353-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6968091" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-09-19
    Description: Yeast transformation can be used to insert new sequence arrangements into a variety of chromosomal locations by homologous recombination. These newly inserted sequences can recombine with similar sequences located on other chromosomes. In these events, information is duplicated without being lost at the site from which it is derived. Similar mechanisms might be utilized by cells to provide new functions during development or differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, S -- Davis, R W -- GM21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1380-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251545" target="_blank"〉PubMed〈/a〉

    Tumor DNA structure in plant cells transformed by A. tumefaciens (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Crown gall tumors are induced in plants by infection with the soil bacterium Agrobacterium tumefaciens. Because the tumor induction involves transfer of a portion of the tumor-inducing (Ti) plasmid DNA from the bacterium to the plant cells, this system is of interest for the study of genetic exchange as well as tumor induction. The boundaries of the transferred DNA (T-DNA) have been cloned from transformed plant cells of tobacco. Detailed mapping with restriction enzymes and nucleotide sequence analysis of two independent clones were used to study the molecular structure of the ends of the T-DNA. One clone contains the two ends of the T-DNA joined together; the other contains one end of the T-DNA joined to repetitive plant DNA sequences. These studies provide direct evidence that the T-DNA can be integrated into the plant genome. In addition, the data suggest that in the plant, T-DNA can be tandemly repeated. Sequence analysis of the junction of crown gall clone 1 reveals several direct repeats as well as an inverted repeat; these structures may be involved in the transfer of the DNA from Agrobacterium to plant cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zambryski, P -- Holsters, M -- Kruger, K -- Depicker, A -- Schell, J -- Van Montagu, M -- Goodman, H M -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1385-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251546" target="_blank"〉PubMed〈/a〉
