Project description:We hypothesized that CD44+ tumor cells might have an increased capacity for reactive oxygen species (ROS) defense in the gastric tumors of K19-Wnt1/C2mE mice. To address this possibility, we examined the expression of antioxidant genes in tumor cells isolated from K19-Wnt1/C2mE mice by fluorescence-activated cell sorting (FACS). Lineage marker (Lin)–negative cells that were CD44+ or CD44– were thus isolated from the gastric tumors of 30-week-old K19-Wnt1/C2mE mice and subjected to cDNA microarray analysis. The expression of several key antioxidant genes, including those for glutathione peroxidase (GPX) and peroxiredoxin (PRDX) isoforms, was found to be increased in CD44+ tumor cells compared with that in CD44– cells.

Project description:Transgenic mice with prostaglandin E2 pathway in stomach develops gastric tumors. Simultaneous activation of both Wnt pathway and prostaglandin E2 pathway causes gastric adenocarcinoma. Combination of prostaglandin E2 pathway activation and suppression of BMP pathway leads to the development of gastric hamartomas. We used microarrays to find the mechanism of these tumor development and to evaluate whether these mouse models recapitulate human gastric tumors. Glandular stomach from three C57BL/6 wild-type, five K19-Wnt1 transgenic, three K19-C2mE, five K19-Wnt1/C2mE, two K19-Nog, and three K19-Nog/C2mE transgenic mice were used. All mice were female at 18-65 weeks of age.

Project description:Subcutanesouly tumors from both Bmal1+/+ and Bmal1-/- mice were used to isolated stromal vascular fractions (SVF). Tumor cells with GFP+ signals were exclusive. Remain GFP- cells were collected to do RNAseq.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.
