Project description:We here compared gene expression profiles of primary murine hepatocytes (mPC) upon stimulation with 1 ng/ml TGF-beta1 for 20 min, 2 hours and 4 hours with untreated cells. Experiments were done in three independent replicates. The goal of this study was to determine genes regulated by TGF-beta1.

Project description:Invastigation of whole genome gene expression level changes in human osteosarcoma cell line MNNG/HOS sarcospheres,hypoxia-induced sarcospheres and TGF-beta1 induced sarcospheres. A three chip study using total RNA cover from three cultures of human osteosarcoma cell line MNNG/HOS sarcospheres, hypoxia-induced sarcospheres and TGF-beta1-induced sarcospheres. Each chip measures the expression level of 45033 genes from osteosarcoma cell line MNNG/HOS.
Project description:Gene expression profiling of a total of 3,774 genes in primary osteoblastic cells treated with TGF-beta1 Keywords: cytokine response Primary osteoblasts cultured under serum-starved condition were treated or untreated with TGF-beta1 for 24 hr.
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.
