Project description:To elucidate the effect of a prostaglandin D2 receptor DP1 agonist BW245C on concanavalin A (ConA) hepatitis, we performed DNA microarray using SurePrint G3 Mouse GE 8x60K Microarray. Mice were treated with ConA for 3 or 24 hr with vehicle or BW245C . Livers were collected, homogenized, and subjected to total RNA extraction.

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.

Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist . Stromal vascular fractions (SVF) from mice (n = 3/group) that received vehicle or beta3 adrenergic receptor agonist, CL, treatment were served for RNA extraction and hybridization on Affymetrix microarrays. We are trying to find out angiogenic factors genes dynamics during white adipose tissues (WAT) - beige transition.

Project description:To investigate the effect of YTHDF1 on concanavalin A (ConA)-induced hepatitis , we performed RNA-seq with the total RNA extracted from the moue liver. Ythdf1-/- or wild type mice were intravenously injected with ConA (8 mg/kg) or saline for 8 hours. Then, the livers were collected, homogenized, and subjected to total RNA extraction.

Project description:Gene expression profiles of the liver and hepatic inflammatory cells in murine concanavalin A-induced acute hepatitis models by treatment with adipose tissue derived stem cells C57Bl/6 female mice were treated with adipose tissue-derived stem cells immediately or 3 hours after concanavalin A injection. Two hours later, the liver tissues or hepatic inflammatory cells were obtained and gene expression of them were examined by DNA microarray.

Project description:Translational research is commonly performed in the C57B6/J mouse strain, chosen for its genetic homogeneity and phenotypic uniformity. Here, we evaluate the suitability of the white-footed deer mouse (Peromyscus leucopus) as a model organism for aging research, offering a comparative analysis against C57B6/J and diversity outbred (DO) Mus musculus strains. Our study includes comparisons of body composition, skeletal muscle function, and cardiovascular parameters, shedding light on potential applications and limitations of P. leucopus in aging studies. Notably, P. leucopus exhibits distinct body composition characteristics, emphasizing reduced muscle force exertion and a unique metabolism, particularly in fat mass. Cardiovascular assessments showed changes in arterial stiffness, challenging conventional assumptions and highlighting the need for a nuanced interpretation of aging-related phenotypes. Our study also highlights inherent challenges associated with maintaining and phenotyping P. leucopus cohorts. Behavioral considerations, including anxiety-induced responses during handling and phenotyping assessment, pose obstacles in acquiring meaningful data. Moreover, the unique anatomy of P. leucopus necessitates careful adaptation of protocols designed for Mus musculus. While showcasing potential benefits, further extensive analyses across broader age ranges and larger cohorts are necessary to establish the reliability of P. leucopus as a robust and translatable model for aging studies.
