Project description:Postnatal tissue quiescence is generally thought to be a default state in the absence of a proliferative stimulus such as injury. We now demonstrate that in the lung, quiescence in the adult is an actively maintained state and is regulated by paracrine hedgehog signaling. Epithelial-specific deletion of Sonic Hedgehog during normal homeostasis results in a proliferative expansion of the adjacent lung mesenchyme. Injury to the lung epithelium results in decreased hedgehog activation, accompanied by proliferative expansion of the adjacent mesenchyme. Moreover, reconstitution of Hedgehog signaling during epithelial injury attenuated the proliferative expansion of the adjacent mesenchyme. Hedgehog signaling maintains lung quiescence by attenuating PDGF signaling through blocking post-translational processing of PDGF receptor α/β into the mature isoforms. These results indicate that in postnatal tissues, epithelial cells can actively maintain mesenchymal quiescence via paracrine hedgehog activation, and that imbalances in this pathway could lead to aberrant mesenchymal expansion and postnatal disease. Fibroblasts were isolated from mouse lungs and grown in culture in triplicate wells. Samples were treated with vehicle or purmorphamine 5um for 24 hours and RNA was isolated for microarray.

Project description:Purpose: Analysis of the differential gene expression of C3H10T1/2 cells undergoing Hedgehog (Hh) induced osteoblast differentiation compared to unstimulated (DMSO treated) cells and investigation of the differential gene expression caused by Picoberin, a highly potent inhibitor of Hh induced osteoblast differentiation (Comparison of purmorphamin + Picoberin treated C3H10T1/2 cells with purmorphamin + DMSO treated cells) Methods: 80 % confluent C3H10T1/2 cells were treated either with 1.5 µM purmorphamine + DMSO, only DMSO, 1.5 µM purmorphamine + 1 nM Picoberin, 1.5 µM purmorphamine +100 nM Picoberin or DMSO + 100 nM Picoberin for 24h, 48h, 96h or 7 days. Results: Picoberin inhibits osteoblast differentiation

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: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.
