Project description:Gene expression array utilizes the advantage of the big number of the significantly changed genes creating transcriptional profiles of known mutations. Creating gene expression profiles of the animal models with known genetic defect provides great opportunity for further investigation human diseases with unknown etiology. Motheaten mice with mutation in protein tyrosine phosphatase Ptpn6 have massive neutrophilic infiltration within the skin followed by autoinflammatory and autoimmune systemic pathology resembling similarity to neutrophilic dermatoses in human. Keywords: genetic modification We performed microarray study on motheaten mice with novel mutation (meb2) in protein tyrosine phosphatase non-receptor-6 (Ptpn6) in with 5 sick bone marrow samples and 5 wild type controls and found significant difference between these two groups.
Project description:We performed scRNA in sorted LinnegcKit+ bone marrow cells from single and double Bap1 and Trp53 knockout mice to identify transcirptional programs driving erythroleukemia.
Project description:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
Project description:ATAC-seq profiling of Nfat5 KO and wild type macrophages derived from bone marrow (primary cells), treated or not with Lipopolysaccharide (LPS).
Project description:We performed RNA-seq and ChIP-seq in lineage depleted bone marrow cells isolated from single and double Bap1 and Trp53 knockout mice to identify transcirptional and epigenetic programs that drive erythroleukemia.

Project description:In order to investigate the function of Ptpn6 in ALL, we isolated bone marrow cells from Ptpn6 +/fl mice and transformed them with BCR-ABL1. In a second transduction the BCR-ABL1 driven pre-B cells were transformed either with CRE-ERT2 or ERT2 (PMIP) and after 2 days of treatment with 4OH-Tamoxifen (0.5 micromolar) subjected to gene expression analysis.
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.
