Project description:The molecular events promoting the initiation of gastric cancer (GC), the third most lethal cancer worldwide, are ill-defined. Here, we demonstrate that upregulation of miR-200 family members is associated with tumor initiation in the gp130F/F mouse model of early GC. The onset of gastric inflammation-associated adenomatous hyperplasia in gp130F/F mice occurs at ~6 weeks of age, with established intestinal-type tumors (3 months of age) progressively growing until a maximum size is reached at 6 months of age, with some evidence of carcinoma in situ. Since this phenotype histologically mimics early stage human GC, we therefore utilized gp130F/F mice as a model to identify miRNAs involved in the initiating molecular events leading to early stage GC. For this purpose, we performed miRNA microarrays on mouse gastric antrum tissue from gp130F/F and sex-matched littermate wild-type (gp130+/+) control mice aged 4 weeks; this age was chosen since antrum tissue from 4 week old (wo) gp130F/F mice is devoid of any histological signs of inflammation or hyperplasia, and is thus comparable to wild-type gastric antrum tissue

Project description:To quantify gene expression differences in olfactory epithelium between the mouse (Mus musculus) and the Nile rat (Arvicanthis niloticus), paired-end RNA sequencing (RNA-seq) was used to profile olfactory epithelium transcriptomes of six Nile rats and six mice (C57BL/6J) (one male and one female at the age of 8, 12, and 16 weeks for each species).

Project description:The role of microbe in promoting the initiation of gastric cancer (GC), the third most lethal cancer worldwide, are ill-defined. Here, we found that tumor size and weight in gp130F/F mouse stomach at condition were significantly reduced compared to those of at SPF condition. To investigate the underlying mechanism and how host genes were regulated in the presence/absence of microbe, arrays were performed in stomach tissue from gp130F/F and WT at 4 week old at SPF and GF conditions. The onset of gastric inflammation-associated adenomatous hyperplasia in gp130F/F mice occurs at ~6 weeks of age, with established intestinal-type tumors (3 months of age) progressively growing until a maximum size is reached at 6 months of age, with some evidence of carcinoma in situ. Since this phenotype histologically mimics early stage human GC, we therefore utilized gp130F/F mice as a model to identify miRNAs involved in the initiating molecular events leading to early stage GC.

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.
