Project description:The Wilms tumor protein Wt1 is a transcription factor known to play an important role in urogenital development. Mutations in the human Wt1 encoding gene (WT1) lead to several syndromes associated with defective renal and sexual development, namely WAGR-, Denys-Drash-, and Frasier-syndrome. During mammalian embryogenesis, urogenital development starts with formation of the urogenital ridges, consisting of the embryonic kidneys, called mesonephroi, and the gonads. In Wt1 knockout mice, these ridges start to form, degenerate, however, during further embryonic development . Although WT1 and the syndromes associated with its mutation are known for several years, it is still unclear which genes, regulated by Wt1, mediate the whole variety of Wt1's function in gonad and mesonephros development. To obtain a comprehensive view on Wt1-dependent gene activity in developing urogenital ridges, we employed microarray analysis. Comparison of gene expression in Wt1 wild-type and knockout mice, led to the identification of almost 150 genes with differences in expression levels higher than factor three.

Project description:We analyzed global mRNA expression in urogenital ridges of embryos that were either heterozygous for the MM-CM-<llerian Inhibiting Substance type II receptor or homozygously deleted to study the genes regulated by MIS during MM-CM-<llerian duct regression. Approximately 200 mosue embryos were sorted for heterozygous or homozygous deletion of the MISR2, urogenital ridges were collected and the gonads were discarded. mRNA was prepared from pooled ridges and sent for Affymetrix analysis.

Project description:Embryonic day (E)12.5 whole murine embryos, E11.5 - E14.5 whole murine embryos, E11.5 - E14.5, post-natal day (P)3 and P35 murine forelimbs, E14.5 brains, and COL1A2-mutant and COL1A2-WT forelimbs were fractionated and specific fractions were analyzed via LC-MS/MS. Aha-enrichment experiments consisted of in vivo protein labeling with azidohomoalanine (Aha) followed by tissue fractionation of the forelimbs and enrichment of labeled ECM proteins from the final IN pellet ('enriched'). 'Unenriched samples', or the background from which newly synthesized proteins were enriched from, were also analyzed via LC-MS/MS.

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:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

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.
