Project description:Uromodulin is the most abundant urinary protein. It is exclusively produced and released in the urine by renal epithelial cells lining the thick ascending limb of Henle’s loop (TAL). Mutations in UMOD, the gene encoding uromodulin, cause autosomal dominant tubulointerstitial kidney disease uromodulin-related (ADTKD-UMOD). While the primary effect of all mutations, retention in the endoplasmic reticulum (ER), is well established, its downstream effects are still unknown. The aim of this study was to gain insight into ADTKD-UMOD pathogenesis through transcriptional profiling of immortalised mouse TAL cells (mTAL) transduced with lentiviral vectors encoding wild type or mutant (C150S) GFP-tagged human uromodulin.

Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.

Project description:Uromodulin (UMOD) is a secreted glycoprotein exclusively expressed by the cells lining the thick ascending limb of the loop of henle and the early distal tubule of the kidney nephron. Mutations in UMOD that interfere with proper folding of the protein are responsible for a progressive form of interstitial fibrotic kidney disease that leads to end stage renal disease, referred to as Uromodulin Associated Kidney Disease (UAKD). To assess key transcriptional changes associated with the progression of UAKD, we generated a knock-in mouse model harboring the mouse equivalent of the human mutation C148W. We profiled both the whole kidney tissue, as well as the specific UMOD+ cell populaitons in mutant and wild type mice. Analysis of differentially expressed genes in whole tissue and UMOD+ cells revealed a strong TNF-signaling signature, as well as TRIB3 upregulation, which is a key mediator of the intrinsic ER-stress mediated cell death pathway.

Project description:To study effect of VRK1 deletion on spermatogenesis of the mouse, transciptomic analysis of genes in postnatal 8-day testicular cells of wild type and VRK1-deficient Mus musculus was performed. Gene expression in testes from from wild type and VRK1-deficient mutant Mus musculus, respectively, was measured. Four independent experiments for wild type and mutant, respectively, were performed.

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:Background: Uromodulin (Tamm-Horsfall) protein is secreted by the thick ascending limb into urine and crosses the basolateral membrane into the kidney interstitium and blood. Uromodulin may engage the kidney’s innate immune system with pro and anti-inflammatory effects described. Mutations in the UMOD gene are a cause of autosomal dominant tubulointerstitial kidney disease (ADTKD) due to protein misfolding and endoplasmic reticulum stress. We identified a family with a UMOD mutation (C106F) that leads to glomerular and interstitial inflammation atypical for ADTKD. Methods: To determine if the observed phenotype is due to mutant uromodulin induced changes in the innate or adaptive immune system, we developed a transgenic (tg) mouse with a homologous cysteine to phenylalanine mutation (C105F) in the UMOD gene using CRISPR-Cas9 gene editing. Results: LLC-PK1 cells expressing wt and mutant protein had increased basolateral secretion of protein compared with cells expressing wt or mutant protein alone. EM examination of mutant medium showed protein aggregates in contrast to filaments in wt medium. Immunoprecipitation of plasma uromodulin from mutant mice demonstrated aggregate formation not seen in wt mice. Tg/+ mice displayed increased F4/80+ mononuclear phagocyte (MP) and podocyte inflammasome activity at baseline. Tg/+ mice developed glomerular and interstitial matrix deposition, myofibroblast proliferation and increased Creatinine with aging. Following ischemia-reperfusion injury, tg/+ mice had no increase in inflammasome activation over baseline in contrast to wt littermates and displayed improved tubular repair and renal function at 7 days. Differential gene expression analysis by RNA sequencing of kidney MP revealed activation of the ATF4 mediated stress response pathway and genes associated with the development of tissue fibrosis. Conclusions: The C106F mutation results in glomerular and interstitial inflammatory kidney disease due to interaction of aggregated misfolded protein with mononuclear phagocytic cells resulting in ER stress response. The resulting alteration in the immune system leads to improved kidney repair following acute injury but fibrosis and chronic renal failure with aging.

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.
