Project description:Since the NFI transcription factors have been shown to be key regulators of gliogenesis, we utilized this pathway to identify miRNAs involved in the regulation of the neurogenesis-to-gliogenesis switch by neural stem/progenitor cells (NSPCs). We focused on miRNAs with expression levels that were differentially regulated downstream of NFIA, and established a mouse embryonic stem cell (ESC) line that expresses NFIA in a doxycycline (Dox)-dependent manner. NFIA-overexpressing (OE) and control NSPCs (neurospheres) derived from ESCs were purified from their mixed cultures (primary neursphsres (PNs) or secondary neurospheres (SNs) ) by fluorescence activated cell sorting and subjected to miRNAarray analysis.

Project description:Mammalian neural stem/progenitor cells (NSPCs) sequentially generate neurons and glia during central nervous system (CNS) development. Several transcription factors and microRNAs (miRNAs) are involved in the temporal regulation of NSPC differentiation. miRNA-153 (miR-153) as a modulator of NSPC specification. Overexpression (OE) of miR-153 delayed the onset of astrogliogenesis and maintained NSPCs in an undifferentiated state in vitro. miR-153-OE and control NSPCs (tertiary neurospheres (TNs) derived from mouse ES Cells via embryoid body formation) subjected to the gene expression microarray analysis.

Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.

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.
