Project description:Microarray analysis of WT (Pten2fl/fl:Shp2fl/fl:Alb-Cre-), SKO (Shp2hep-/-, or Shp2fl/fl:Alb-Cre+), PKO (Ptenhep-/-, or Pten2fl/fl:Alb-Cre+) and DKO (Ptenfl/fl:Shp2fl/fl:Alb-Cre+) liver samples to gain global molecular insights how shp2 and pten is involved in liver tumorigenesis.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to reveal dynamics of liver tumourigenesis in different mouse model and identify some key regulators that control HCC initiation or progression. We also try to define a index based on transcriptome of samples to quantify tumor development stage. Methods: mRNA profiles of wild-type (WT), hepatocyte-specific shp2 deletion (Shp2−/−) mice (SKO), hepatocyte-specific pten deletion (Pten−/−) mice (PKO), and hepatocyte-specific shp2 and pten deletion mice (DKO) were generated by deep sequencing. The sequence reads that passed quality filters were mapped to Mouse genome using STAR, and mRNA profiles were obtained using cuffdiff. Results: quanlity control of mRNA profiles showed that the data captured key features of phenotypes. Significantly changed genes, pathways, biolgocial processes, ligand and receptor, epigenetic regulators et al of SKO, PKO, DKO mice at differnet age were obtaiend. Temporal gene expression patterns during liver tumorigenesis in SKO, PKO and DKO mice were obtained. Conclusions: Our study represents the first detailed analysis of temporal transcriptomes during liver tumourigenesis, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comprehensive investigations of expression profiles.

Project description:The ketogenic diet has been successful in promoting weight loss among patients that have struggled with weight gain. This is due to the cellular switch in metabolism that utilizes liver-derived ketone bodies for the primary energy source rather than glucose. Fatty acid transport protein 2 (FATP2) is highly expressed in liver, small intestine, and kidney where it functions in both the transport of exogenous long chain fatty acids (LCFA) and in the activation to CoA thioesters of very long chain fatty acids (VLCFA). We have completed a multi-omic study of FATP2-null (Fatp2-/-) mice maintained on a ketogenic diet (KD) or paired control diet (CD), with and without a 24-hour fast (KD-fasted and CD-fasted) to address the impact of deleting FATP2 under high-stress conditions. Control (wt/wt) and Fatp2-/- mice were maintained on their respective diets for 4-weeks. Afterwards, half the population was sacrificed while the remaining were fasted for 24-hours prior to sacrifice. We then performed paired-end RNA-sequencing on the whole liver tissue to investigate differential gene expression. The differentially expressed genes mapped to ontologies such as the metabolism of amino acids and derivatives, fatty acid metabolism, protein localization, and components of the immune system’s complement cascade, and were supported by the proteome and histological staining.

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:The goal of this study was to perform transcriptomics on wildtype, PTEN single knockout (SKO) and PTEN;Rb1 double knockout (DKO) mouse prostate organoids. We isolated basal cells from PTEN floxed and PTEN;Rb1 floxed mouse prostates and infected with either RFP control or Cre recombinase to establish wildtype, SKO, and DKO mouse prostate organoids.

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.
