Project description:To determine the role of Osgep in beta cell function, we generated beta cell specific Osgep knockout mice and assessed their glucose homeostasis, islet morphology, and protein expression. For the TMT-based proteomics analysis, islets were collected from male Osgep-Ins2-Cre mice and littermate control mice (N = 3).
Project description:Histones were isolated from brown adipose tissue and liver from mice housed at 28, 22, or 8 C. Quantitative top- or middle-down approaches were used to quantitate histone H4 and H3.2 proteoforms. See published article for complimentary RNA-seq and RRBS datasets.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
Project description:To determine the role of Ascl1 in beta cell development, function, and metabolic stress response, we generated beta cell specific Ascl1 knockout mice and assessed their glucose homeostasis, islet morphology, and gene expression after feeding a normal diet, a high fat diet (HFD) for 12 weeks, or on a background of Abcc8 (KATP channel subunit) knockout mice. For the RNA-seq analysis, islets from male Ascl1betaKO and littermate control mice (N = 4 for each genotype and condition) were collected from three different conditions: 1) normal diet fed 2) HFD fed for 12 weeks, 3) on a background of homozygous Abcc8 allele.
