Project description:Pglyrp1-/-, Pglyrp2-/-, Pglyrp3-/-, and Pglyrp4-/- mice are all more sensitive than wild type (WT) mice to dextran sulfate sodium (DSS)-induced colitis. The purpose of this study was to determine which genes are differentially induced by DSS treatment in the colon of Pglyrp1-/-, Pglyrp2-/-, Pglyrp3-/-, and Pglyrp4-/- mice compared to WT mice. The results demonstrate higher induction of proinflammatory gene expression in Pglyrp1-/-, Pglyrp2-/-, Pglyrp3-/-, and Pglyrp4-/- mice than in WT mice after DSS treatment. The majority of genes whose expression is increased in Pglyrp1-/-, Pglyrp2-/-, Pglyrp3-/-, and Pglyrp4-/- mice but not in WT mice are interferon-inducible genes. Thus, Peptidoglycan Recognition Proteins Pglyrp1, Pglyrp2, Pglyrp3, and Pglyrp4 protect mice from excessive inflammatory response and damage to the colon by limiting expression of interferon-inducible genes in the colon.
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:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
Project description:The objective of the study was to evalute the changes in gene expression associated to UCP2 invalidation in colon tumors from AOM/DSS-treated mice We used microarrays (Mouse Gene 2.0) to investigate gene expression in Ucp2+/+ and Ucp2-/- colon tumors
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.
