We have used an interspecific backcross between C57BL/6J and Mus spretus to derive a molecular genetic linkage map of chromosome 15 that includes 25 molecular markers and spans 93% of the estimated length of chromosome 15. Using a second interspecific backcross that was analyzed with a centromere-specific marker, we were also able to position our map with respect to the chromosome 15 centromere. This map provides molecular access to many discrete regions on chromosome 15, thus providing a framework for establishing relationships between cloned DNA markers and known mouse mutations and for identifying homologous genes in mice and humans that may be involved in disease. 相似文献

An interspecific backcross between C57BL/6J and Mus spretus was used to generate a molecular genetic linkage map of mouse chromosome 18 that includes 23 molecular markers and spans approximately 86% of the estimated length of the chromosome. The Apc, Camk2a, D18Fcr1, D18Fcr2, D18Leh1, D18Leh2, Dcc, Emb-rs3, Fgfa, Fim-2/Csfmr, Gnal, Grl-1, Grp, Hk-1rs1, Ii, Kns, Lmnb, Mbp, Mcc, Mtv-38, Palb, Pdgfrb, and Tpl-2 genes were mapped relative to each other in one interspecific backcross. A second interspecific backcross and a centromere-specific DNA satellite probe were used to determine the distance of the most proximal chromosome 18 marker to the centromere. The interspecific map extends the known regions of linkage homology between mouse chromosome 18 and human chromosomes 5 and 18 and identifies a new homology segment with human chromosome 10p. It also provides molecular access to many regions of mouse chromosome 18 for the first time. 相似文献

The Chediack-Higashi syndrome (CHS) is an autosomal recessive disorder reported in man and in several animal species including the "beige mice" (bg/bg). Among several manifestations of this genetic trait, deficiency of secretable substances - including serotonin - normally stored in platelet dense granules is a characteristic feature. The animal model of Chediak-Higashi syndrome used in the present study provides a unique opportunity to compare the kinetics of serotonin (5-hydroxytryptamine, 5-HT) uptake in platelets and brain synaptosomes in conditions of selective reduction of 5HT concentration in the platelets. The kinetics of 5HT uptake, as measured in the present study, was normal in synaptosomes and platelets from the same animals. The lower intraplatelet 5HT levels in bg/bg animals as compared to normal synaptosomes levels in the presence of normal uptake offer an indirect proof that the 5HT defect described in the CHS is due to an impaired 5HT storage mechanism. This is supported by the observation that spontaneous release of 5HT was markedly increased in platelets from CH5 mice but was normal in synaptosomes from the same animals. Thus platelets are a reliable model to study 5HT uptake, but not 5HT storage and release in brain synaptosomes. 相似文献

A tRNAVal (GAC) gene is located in opposite orientation 552 nucleotides (nt) down-stream of the cytochrome oxidase subunit III (coxIII) gene in sunflower mitochondria. The comparison with the homologous chloroplast DNA revealed that the tRNAVal gene is part of a 417 nucleotides DNA insertion of chloroplast origin in the mitochondrial genome. No tRNAVal is encoded in monocot mitochondrial DNA (mtDNA), whereas two tRNAVal species are coded for by potato mtDNA. The mitochondrial genomes of different plant species thus seem to encode unique sets of tRNAs and must thus be competent in importing the missing differing sets of tRNAs. 相似文献

Diazepam in vitro produced a concentration-dependent increase of membrane fluidity in crude synaptic membranes from rat hippocampus, but not cerebellum. Similar effects were obtained with higher concentrations of Ro 15-1788 and PK 11195, while zopiclone was completely inactive. In vivo acute treatment with diazepam and Ro 15-1788 gave results similar to those in vitro. The specific benzodiazepine antagonist also significantly increased membrane fluidity and was not able to reverse diazepam's effect. The data are discussed in terms of a possible role of protein kinase inhibition by the drugs not mediated by the 'central' or 'peripheral' type of benzodiazepine receptors. 相似文献
