    Description: In a search for genes that regulate circadian rhythms in mammals, the progeny of mice treated with N-ethyl-N-nitrosourea (ENU) were screened for circadian clock mutations. A semidominant mutation, Clock, that lengthens circadian period and abolishes persistence of rhythmicity was identified. Clock segregated as a single gene that mapped to the midportion of mouse chromosome 5, a region syntenic to human chromosome 4. The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3839659/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3839659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vitaterna, M H -- King, D P -- Chang, A M -- Kornhauser, J M -- Lowrey, P L -- McDonald, J D -- Dove, W F -- Pinto, L H -- Turek, F W -- Takahashi, J S -- P30-CA07175/CA/NCI NIH HHS/ -- R01-DK40493/DK/NIDDK NIH HHS/ -- T32 NS071040/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):719-25.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171325" target="_blank"〉PubMed〈/a〉

    Description: In a pedigree derived from a mouse treated with the mutagen ethylnitrosourea, a mutation has been identified that predisposes to spontaneous intestinal cancer. The mutant gene was found to be dominantly expressed and fully penetrant. Affected mice developed multiple adenomas throughout the entire intestinal tract at an early age.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moser, A R -- Pitot, H C -- Dove, W F -- CA07175/CA/NCI NIH HHS/ -- CA50585/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Jan 19;247(4940):322-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McArdle Laboratory for Cancer Research, University of Wisconsin-Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2296722" target="_blank"〉PubMed〈/a〉

    Description: Germ-line mutations of the APC gene are responsible for familial adenomatous polyposis (FAP), an autosomal dominantly inherited disease in humans. Patients with FAP develop multiple benign colorectal tumors. Recently, a mouse lineage that exhibits an autosomal dominantly inherited predisposition to multiple intestinal neoplasia (Min) was described. Linkage analysis showed that the murine homolog of the APC gene (mApc) was tightly linked to the Min locus. Sequence comparison of mApc between normal and Min-affected mice identified a nonsense mutation, which cosegregated with the Min phenotype. This mutation is analogous to those found in FAP kindreds and in sporadic colorectal cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, L K -- Kinzler, K W -- Vogelstein, B -- Preisinger, A C -- Moser, A R -- Luongo, C -- Gould, K A -- Dove, W F -- CA-06973/CA/NCI NIH HHS/ -- CA-07175/CA/NCI NIH HHS/ -- CA-23076/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 May 1;256(5057):668-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1350108" target="_blank"〉PubMed〈/a〉

    Notes: Abstract We present here a detailed physical map encompassing over 600 kb of mouse Chromosome (Chr) 17 in the region of plasminogen, D17Rp17e, and quaking. This region is cloned in yeast artificial chromosomes (YACs). We have identified several CpG islands within this region from pulsed field gel mapping of mouse genomic DNA and YAC DNA. Five new DNA probes have been generated. One, D17Leh514, is a minimum of about 90 kb distal to plasminogen. Four, D17Leh513, D17Leh512, D17Leh511, and D17Leh510, are proximal to D17Rp17e, the closest previously described genetic marker to quakingviable and quakinglethal-1 mutations. We have genetically mapped D17Leh511 to within 0.15 cM of these mutations. The genetic distance to D17Rp17e from D17Leh511 is also 0.15 cM; the physical distance of less than 360 kb (minimum 200 kb) is consistent with an approximation of 2 Mbp per cM.

    Notes: Summary Mutations c17 and ri c, which permit constitutive expression of genes O and P and transcriptional activation of λ DNA replication, act as new promoters since they map outside the immunity region and direct rightward transcription in the presence of repressor. In the λc17 P -or λri cP- lysogens, this constitutive transcription is restricted to the O-P region, and is at least one order of magnitude lower than that for an induced λP -lysogen. The operator-constitutive mutants v2 and v1v3 give very low levels of constitutive transcription from the l and r strands, respectively.

    Notes: Abstract Male-specific antigen expression by XY teratocarcinomas PCC7 and 7′ is demonstrated first by the rejection of tumors by female but not by male mice following challenge with these cell lines. Male-specific antigen expression is confirmed by an indirect method in which females are immunized against H-Y antigen by male skin grafts. A variant of PCC7 lacking male-specific antigen expression is described. Analysis of the karyotype and of the DNA from this variant indicate that the loss of male-specific antigen expression is a result of the loss of the Y chromosome. The ability to recover variants that have lost expression of male-specific antigen opens the possibility of their selection after mutagenesis.

    Notes: Abstract Two cultured lines of murine embryonal carcinoma, F9 and PCC3, have been grafted to a variety of allogeneic hosts. The host strains have been classified by their resistance or sensitivity to these carcinomas. Resistance seems to be immunological in nature. Allograft rejection does not correlate withH-2 haplotype, and seems to be controlled by a limited number of recessive factors, presumably histocompatibility genes. We infer that these factors have limited polymorphism in the mouse species. Recombinational analysis of strain A/He has revealed the presence of a recessive factor linked to theH-2 locus. Tumor resistance of strains C57BL/6 and AKR appears to result from the interaction of dominant or semi-dominant factors in theH-2 region with other recessive elements in the genetic background. Though F1 hybrids between resistant mouse strains and the syngeneic strain 129 are largely tumor-sensitive, a low level of hybrid resistance to F9 has been observed and shown to be eliminated by X-irradiation.

    Notes: Abstract During the life cycle of Physarum polycephalum, uninucleate amoebae develop into multinucleate syncytial plasmodia. These two cell types differ greatly in cellular organisation, behaviour and gene expression. Classical genetic analysis has identified the mating-type gene, matA, as the key gene controlling the initiation of plasmodium development, but nothing is known about the molecular events controlled by matA. In order to identify genes involved in regulating plasmodium formation, we constructed a subtracted cDNA library from cells undergoing development. Three genes that have their highest levels of expression during plasmodium development were identified: redA, redB (regulated in development) and mynD (myosin). Both redA and redB are single-copy genes and are not members of gene families. Although redA has no significant sequence similarities to known genes, redB has sequence similarity to invertebrate sarcoplasmic calcium-binding proteins. The mynD gene is closely related to type II myosin heavy-chain genes from many organisms and is one of a family of type II myosin genes in P. polycephalum. Our results indicate that many more red genes remain to be identified, some of which may play key roles in controlling plasmodium formation.

    Description: It recently has been recognized that men develop colonic adenomas and carcinomas at an earlier age and at a higher rate than women. In the ApcPirc/+ (Pirc) rat model of early colonic cancer, this sex susceptibility was recapitulated, with male Pirc rats developing twice as many adenomas as females. Analysis...
