Project description:Multipotent C3H10T1/2 cells can be induced to differentiate into mature brown adipocytes by 3-days BMP7 pretreatment followed by standard adipogenic induction. We used microarrays to detail the global programme of gene expression in C3H10T1/2 cells after 3-day BMP7 (3.3 nM) treatment.
Project description:Multipotent C3H10T1/2 cells can be induced to differentiate into mature brown adipocytes by 3-days BMP7 pretreatment followed by standard adipogenic induction. In this study, we used microRNA array to identify the microRNAs that were regulated by 3-days BMP7 treatment in C3H10T1/2 cells. One BMP7-treated sample and one vehicle-treated sample were used in this study to obtain the fold expression of microRNAs between BMP7 vs vehicle.

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.
