    Description: The circumsporozoite (CS) protein of Plasmodium falciparum is the focus of intense efforts to develop an antisporozoite malaria vaccine. Localization of sites for T-cell recognition on this molecule is critical for vaccine design. By using an algorithm designed to predict T-cell sites and a large panel of H-2 congenic mice, a major nonrepetitive T-cell site was located. When a synthetic peptide corresponding to this site was covalently linked to the major B-cell site on the molecule, an immunogen capable of eliciting a high-titer antibody response was formed. This peptide sequence could prime helper T cells for a secondary response to the intact CS protein. The new helper T-cell site is located outside the repetitive region of the CS protein and appears to be the immunodominant T site on the molecule. This approach should be useful in the rational design and construction of vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Good, M F -- Maloy, W L -- Lunde, M N -- Margalit, H -- Cornette, J L -- Smith, G L -- Moss, B -- Miller, L H -- Berzofsky, J A -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1059-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434994" target="_blank"〉PubMed〈/a〉

    Description: Lineage-specific regulatory elements can be used to direct expression of a variety of genes to specific tissues in transgenic mice. If the hybrid constructs contain a gene encoding a cytotoxic gene product, then genetic ablation of a specific cell lineage can be achieved. We have generated six transgenic mice by introducing into fertilized eggs the mouse gamma 2-crystallin promoter fused to the coding region of the diphtheria toxin A-chain gene. Three of these mice and all the transgenic offspring analyzed were microphthalmic. The lenses of these mice displayed considerable heterogeneity: some were almost normal morphologically but reduced in size, whereas others were grossly aberrant and deficient in nuclear fiber cells. These studies indicate that programmed ablation of specific cell types can be stably transmitted through the germ line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breitman, M L -- Clapoff, S -- Rossant, J -- Tsui, L C -- Glode, L M -- Maxwell, I H -- Bernstein, A -- CA 42354/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Dec 11;238(4833):1563-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685993" target="_blank"〉PubMed〈/a〉

    Description: As part of a study of potential vaccines against malaria, the protective efficacy of sporozoite subunit vaccines was determined by using the Plasmodium berghei murine malaria model. Mice were immunized with recombinant DNA-produced or synthetic peptide-carrier subunit vaccines derived from the repetitive epitopes of the Plasmodium berghei circumsporozoite gene, or with radiation-attenuated sporozoites. Immunization with subunit vaccines elicited humoral responses that were equivalent to or greater than those elicited by irradiated sporozoites, yet the protection against sporozoite challenge induced by either of the subunit vaccines was far less than that achieved by immunization with attenuated sporozoites. Passive and adoptive transfer studies demonstrated that subunit vaccines elicited predominantly antibody-mediated protection that was easily overcome whereas irradiated sporozoites induced potent cell-mediated immunity that protected against high challenge doses of sporozoites. These studies indicate that new strategies designed to induce cellular immunity will be required for efficacious sporozoite vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Egan, J E -- Weber, J L -- Ballou, W R -- Hollingdale, M R -- Majarian, W R -- Gordon, D M -- Maloy, W L -- Hoffman, S L -- Wirtz, R A -- Schneider, I -- New York, N.Y. -- Science. 1987 Apr 24;236(4800):453-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3551073" target="_blank"〉PubMed〈/a〉

    Description: Mammalian X-chromosome inactivation involves a coordinate shutting down of physically linked genes. Several proposed models require the presence of specific sequences near genes to permit the spread of inactivation into these regions. If such models are correct, one might predict that heterologous genes transferred onto the X chromosome might lack the appropriate signal sequences and therefore escape inactivation. To determine whether a foreign gene inserted into the X chromosome is subject to inactivation, transgenic mice harboring 11 copies of the complete, 17-kilobase chicken transferrin gene on the X chromosome were used. Male mice hemizygous for this insert were bred with females bearing Searle's translocation, an X-chromosome rearrangement that is always active in heterozygous females (the unrearranged X chromosome is inactive). Female offspring bearing the Searle's translocation and the chicken transferrin gene had the same amount of chicken transferrin messenger RNA in liver as did transgenic male mice or transgenic female mice lacking the Searle's chromosome. This result shows that the inserted gene is not subject to X-chromosome inactivation and suggests that the inactivation process cannot spread over 187 kilobases of DNA in the absence of specific signal sequences required for inactivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldman, M A -- Stokes, K R -- Idzerda, R L -- McKnight, G S -- Hammer, R E -- Brinster, R L -- Gartler, S M -- HD14412/HD/NICHD NIH HHS/ -- HD16659/HD/NICHD NIH HHS/ -- HD17321/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1987 May 1;236(4801):593-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2437652" target="_blank"〉PubMed〈/a〉

    Description: Transgenic mice carrying the gamma 2-crystallin promoter fused to the coding region of the bacterial lacZ gene were generated. The offspring of three founder mice expressed high levels of the enzyme solely in the central nuclear fiber cells of the lens as measured by an in situ assay for the detection of beta-galactosidase activity. These results suggest that gamma 2-crystallin sequences between -759 to +45 contain essential information required for appropriate tissue-specific and temporal regulation of the mouse gamma 2-crystallin gene. In a broader context, this study also demonstrates the utility of beta-galactosidase hybrid gene constructs for monitoring the activity of gene regulatory elements in transgenic mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goring, D R -- Rossant, J -- Clapoff, S -- Breitman, M L -- Tsui, L C -- New York, N.Y. -- Science. 1987 Jan 23;235(4787):456-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3099390" target="_blank"〉PubMed〈/a〉

    Description: In initial attempts to define the molecular events responsible for the latent state of herpes simplex virus, in situ hybridization was utilized to search for virally encoded RNA transcripts in latently infected sensory neurons. The use of cloned probes representing the entire viral genome indicated that transcripts encoded within terminal repeats were present. When the alpha genes encoding ICP-0, ICP-4, and ICP-27 and the gamma 1 gene encoding VP-5 were employed, only RNA transcripts hybridizing to the ICP-0 probe were detected. In latently infected cells, the ICP-0--related transcripts were localized principally in the nucleus; this was not the case in acutely (productively) infected neurons or in neurons probed for RNA transcripts coding for actin. In Northern blotting experiments, an RNA of 2.6 kilobases was detected with the ICP-0 probe. When single-stranded DNAs from the ICP-0 region were used as probes, RNA from the strand complementary to that encoding ICP-0 messenger RNA (mRNA) was the major species detected. This RNA species may play a significant role in maintaining the latent infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, J G -- Wagner, E K -- Devi-Rao, G B -- Cook, M L -- Feldman, L T -- AI-06246/AI/NIAID NIH HHS/ -- CA 11861/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1056-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434993" target="_blank"〉PubMed〈/a〉

    Notes: Summary A short-term selection experiment for increasing the first-day litter size (LS1) and 28-day litter weight (LW28) was conducted with three populations of mice over 8 generations. Different methods of litter size manipulation were used for the populations — in S the litter size was standardized to 8 (4 ♂ ♂, 4 ♀♀) on the first day, in LA it was adjusted to the average size of all litters born on the same day and NL had the natural litter size. To eliminate temporary environmental effects, a control population was kept in each case. The selection results per generation were, for LS 1 b=0.30 (S, NL) and 0.20 (LA), and for LW28 b=5.62 g (S), 5.26 g (NL), and 4.32 g (LA). The heritability obtained was between 0.18 and 0.13 for LS 1 and from 0.42 to 0.12 for LW28. The populations differed in the correlated responses for body weight parameters (litter weight gain). The implantation rate increased in populations S and NL (b=0.19, 0.37), but not in population LA. Postnatal mortality went down (b=-0.07) and the dam's milk production rose (b=1.11 g) only in population LA. The estimated partial regression coefficient linking body weight at mating (BWM) for the dam and the daughter's litter size showed an effect on the litter size.

    Notes: Summary The PAP-technique and antibodies to myosin were used to demonstrate the prerequisites for vasoconstriction in the juxtaglomerular part of the preglomerular arteriole as compared with its proximal segment in rats and mice. In contrast with the myosin-positive/renin-negative proximal part of the afferent arteriole no myosin-like activity could be demonstrated in its distal, renin-positive part. In accordance, no thick myofilaments were found in fully differentiated juxtaglomerular epithelioid cells replete with mature secretory granules. Stimulation of the renin-angiotensin system was followed by an increase of the reninpositive/myosin-negative portions of the preglomerular arteriole. Marked interspecies and internephron variations in the length of this vessel segment under control and stimulated conditions were observed. The juxtaglomerular part of the preglomerular arteriole close to the macula densa seems therefore to have only limited capabilities for vasoconstriction. This finding may be of importance regarding the tubulo-glomerular feedback, a mechanism allegedly triggered by the so-called ‘macula densa-signal’. It is suggested that this non-contractile segment of the afferent arteriole may represent the renal vascular receptor responsible for the increase of renin secretion during pressure reduction. Unlike the afferent arterioles, most of the efferent arterioles showed the highest level of their weak but distinct myosin-like immunoreactivity in the juxtaglomerular region, indicating some efferent juxtaglomerular vasoconstrictive ability.

    Description: Li-Fraumeni syndrome is manifested in a variety of neoplasms that are transmitted in a dominantly inherited pattern. The noncancerous skin fibroblasts of family members exhibit a unique characteristic of being resistant to the killing effect of ionizing radiation. A three- to eightfold elevation in expression of c-myc and an apparent activation of c-raf-1 gene have been observed in these noncancerous skin fibroblasts. These results may provide insight into the heritable defect underlying the familial predisposition to a variety of cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, E H -- Pirollo, K F -- Zou, Z Q -- Cheung, H Y -- Lawler, E L -- Garner, R -- White, E -- Bernstein, W B -- Fraumeni, J W Jr -- Blattner, W A -- CA45158/CA/NCI NIH HHS/ -- CO7488/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 28;237(4818):1036-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3616624" target="_blank"〉PubMed〈/a〉
