Project description:Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a genetic disorder caused by loss-of-function mutations in PKD1 or PKD2. Increased glycolysis is a prominent feature of the disease, but how it impacts on other metabolic pathways is unknown. Here, we present an analysis of mouse Pkd1 mutant cells and kidneys to investigate the metabolic reprogramming of this pathology. We show that loss of Pkd1 leads to profound metabolic changes that affect glycolysis, mitochondrial metabolism, and fatty acid synthesis (FAS). We find that Pkd1-mutant cells preferentially use glutamine to fuel the TCA cycle and to sustain FAS. Interfering with either glutamine uptake or FAS retards cell growth and survival. We also find that glutamine is diverted to asparagine via asparagine synthetase (ASNS). Transcriptional profiling of PKD1-mutant human kidneys confirmed these alterations. We find that silencing of Asns is lethal in Pkd1-mutant cells when combined with glucose deprivation, suggesting therapeutic approaches for ADPKD.

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:Autosomal Dominant Polycystic Kidney Disease (ADPKD; MIM ID’s 173900, 601313, 613095) leads to end stage kidney disease, caused by mutations in PKD1 or PKD2. Inactivation of Pkd1 before or after P13 in mice results in distinct early- or late-onset disease. Using a mouse model of ADPKD carrying floxed Pkd1 alleles disrupted using a tamoxifen-inducible Cre recombinase, transcriptomics and metabolomics were applied to follow disease progression in animals induced before P10. Network analysis suggests that Pkd1-cystogenesis does not cause developmental arrest and occurs in the context of gene networks similar to those that regulate/maintain normal kidney morphology/function. These analyses also predict metabolic pathways, notably those controlled by HNF4α, are key elements in postnatal kidney maturation and early steps of cyst formation. To test this hypothesis, metabolic networks were altered by inactivating Hnf4a and Pkd1. The Pkd1/Hnf4a double knock-out have significantly more cystic kidneys thus indicating that modulating metabolic pathways might be an effective therapeutic approach. We crossed fifth-generation C57/BL6 Pkd1cond mice to fifth-generation C57/BL6 tamoxifen-Cre (B6.Cg-Tg(Cre/Esr1)5Amc/J mice (stock 004682), Jackson Laboratories) and C57/BL6 congenic B6.129S4-Gt(ROSA)26Sortm1Sor/J (stock 003474, Jackson Laboratories) to produce Pkd1 conditional mice with TamCre (mutant) or without TamCre (control). We induced Cre recombinase activity in mice < 10 days of age by intraperitoneally injecting nursing mothers with tamoxifen (10 mg/40 g) , and harvested kidney samples of control and mutant (34 and 36 animals, respectively) between the ages of 11 and 24 days.

Project description:Purpose: Determine the differential m6A methylation pattern of Mettl3 between wildtype, Pkd1F/RC-KO and Pkd1F/RC-Mettl3-DKO mouse kidneys. Methods: m6A RNA IP using the Magna MeRIP™ m6A Kit (EMD Millipore, catalog #17-10499) was performed on P18 wildtype, Pkd1F/RC-KO and Pkd1F/RC-Mettl3-DKO mouse kidney samples. Two biological replicate samples from each genotype were sequenced. Each sample was a pool of 6 kidneys of the same genotype. The input samples were also sequenced to obtain mRNA profiles. Results: 133 mRNAs were found to be differentially hypermethylated in the Pkd1-KO kidneys compared to the control kidneys and differentially hypomethylated in the Pkd1-Mettl3-DKO kidneys compared to the Pkd1-KO kidneys. Two key pathogenic mRNAs namely, c-Myc and Avpr2 were identified and validated as Mettl3 targets. The mRNA transcript levels were unchanged between Pkd1-KO and Pkd1-Mettl3-DKO kidneys. Conclusion: Mettl3/m6A promotes translation of pathogenic mRNAs to mediate cystogenesis in mouse models of ADPKD.

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.
