Project description:Male C57BL/6J mice were fed a high-fat diet (HFD, 60 kcal% fat, D12492, Research Diets, Inc) or normal standard chow diet with 10 kal% fat (ND, D09100304, Research Diets, Inc). Specifically, 6-week-old mice were fed a HFD for 12 weeks to induce insulin resistance (HFD-12w group); 14-week-old mice were fed a HFD for 4 weeks to induce obesity (HFD-4w group). Control mice were fed a ND continuously for 12 weeks starting at 6 weeks of age (ND group). All mice reached the experimental endpoint at 18 weeks of age. Insulin sensitivity was measured by glucose tolerance test and insulin tolerance test. Mice that developed insulin resistance in HFD-12w group and obese mice with normal insulin sensitivity in HFD-4w group were used for further experiments. Mice in ND group were used as controls. Upon reaching the experimental endpoint, livers from three insulin-resistant mice, three insulin-sensitive obese mice, and three control mice were removed for RNA sequencing.

Project description:The popularity of high fat foods in modern society has been associated with epidemic of various metabolic diseases characterized by insulin resistance, the pathology of which involves complex interactions between multiple tissues such as liver, skeletal muscle and white adipose tissue (WAT). To uncover the mechanism by which excessive fat impairs insulin sensitivity, we conducted a multi- tissue study by using TMT-based quantitative proteomics. 3-week-old ICR mice were fed with high fat diet (HFD) for 19 weeks to induce insulin resistance. Liver, skeletal muscle and epididymal fat were collected for proteomics screening. Additionally, PRM was used for validating adipose differential proteins. By comparing tissue-specific protein profiles of HFD mice, multi-tissue regulation of glucose and lipid homeostasis and corresponding underlying mechanisms was systematically investigated and characterized.

Project description:To determine whether paternal methamphetamine exposure alters the development, behavior and gene expression of first (F1) and second (F2) generations. We administrated methamphetamine (5 mg/kg) or saline (10 ml/kg) to sire (F0) and performed gene expression profiling analysis using data obtained from RNA-seq of striatum of 7-week-old male F1 mice. Male F1 mice were mated with untreated female mice to obtain F2 mice. Male F1 mice were mated with female mice to obtain F2 mice. RNA-seq of striatum of 7-week-old male F2 mice was also analyzed in the same way.

Project description:Purpose: To investigate the effects of paternal high cholesterol diet on the F1 intimal transcriptome related to atherosclerosis. Methods:Three-week-old male LDL Receptor-deficient (LDLR-/-) male mice were fed a low-cholesterol diet (LCD) or high-cholesterol diet (HCD) for 8 weeks and then mated with age-matched control LDLR-/- female mice to generate F1 offspring. F1 LDLR-/- mice were fed a LCD for 16 weeks. Intimal RNA was extracted by injecting Trizol into the aorta and collecting the flow through for further processing. Results: . Total RNA isolated from the F1 intima were then subjected for RNA-sequencing analysis and results show that paternal hypercholesterolemia led to upregulation of 147 genes in the intimal of F1 female mice, many of which are involved in immune and inflammatory pathways.

Project description:We investigated parent-of-origin and allele-specific expression effects on obesity and hepatic gene expression in reciprocal crosses between the Berlin Fat Mouse Inbred line (BFMI) and C57Bl/6NCrl (B6N). We sequenced mRNA extracted from liver tissue of 10 M. Musculus individuals. 4 liver samples were collected from 10 week old inbred strains (1 male and 1 female Berlin Fat Mouse Inbred line (BFMI), 1 male and 1 female C57Bl/6NCrl (B6N)) and 6 liver samples collected from 10 week old F1 males using a reciprocal cross design (3 paternal BFMI (patBFMI) vs 3 maternal BFMI (matBFMI)).

Project description:Spontaneous insulin resistance and NAFLD emerged in AxB F1 male mice with parent-of-origin effects such that AB6F1 (AJ dam x B6 sire) were susceptible whereas B6AF1 (B6 dam x AJ sire) were resistant. We used microarrays to correlate gene expression with the NAFLD phenotype in 9-month-old male AB6F1 (affected) versus B6AF1 (unaffected) mice. Whole liver slices from two 9-month-old AB6F1 and B6AF1 males were collected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Maternal high-fat diet consumption predisposes to metabolic and liver dysfunction in F1 male and female at young adulthood. Purpose: We used RNA-seq to determine the liver transcriptome of male and female F1 of MO and control fed mothers. Methods: Female Wistar rat mothers ate control (C) or obesogenic (MO) diet from the time they were weaned through breeding at postnatal day (PND) 120, delivery and lactation. After weaning all male and female F1 ate control diet. At PND 110 liver and fat were collected to analyze metabolites, histology and liver differentially expressed genes. To identify the functional F1 liver changes due to MO, we evaluated the differentially expressed genes (DEGs) between MO and C males and females with separate pairwise comparisons due to the marked differences between males and females. Genes were filtered based on ≥ 1.4 fold change (FC) and nominal P value <0.05 (Student´s t-test). Results: MOF1 males presented greater physiologic and histological NAFLD characteristics than MOF1 females. RNA-seq revealed 1,365 genes significantly changed in male MOF1 liver and only 70 genes in MOF1 female compared with controls. GO and KEGG analysis identified differentially expressed genes related to metabolic process. Male MOF1 liver showed the following altered pathways: insulin signaling (22 genes), phospholipase D signaling (14 genes), NAFLD (13 genes), and glycolysis/ gluconeogenesis (7 genes). In contrast, few genes were altered in these pathways in MOF1 females. Conclusions: These results improve understanding of the mechanism by which a maternal high fat diet affects their F1. In summary, MO programs sex-dependent F1 changes in insulin, glucose and lipid signaling pathways, leading to liver dysfunction and insulin resistance. Male adult MOF1 livers show global down-regulation of genes that are required for normal function of major liver metabolic pathways. This new knowledge is important for producing sex-specific interventions.

Project description:Quercetin is a food component that may ameliorate the diabetic symptoms. We examined hepatic gene expression of BALB/c mice with streptozotocin (STZ)-induced diabetes to elucidate the mechanism of the protective effect of dietary quercetin on diabetes-associated liver injury. We fed STZ-induced diabetic mice with diets containing 0.1% or 0.5% quercetin for 2 weeks and compared the patterns of hepatic gene expression in these groups of mice using a DNA microarray. Diets containing 0.1% or 0.5% quercetin lowered the STZ-induced increase in blood glucose levels and improved plasma insulin levels. A cluster analysis of the hepatic gene expressions showed that 0.5% quercetin diet suppressed STZ-induced alteration of gene expression. Gene set enrichment analysis (GSEA) and quantitative RT-PCR analysis showed that the quercetin diets had their greatest suppressive effect on the STZ-induced elevation of expression of cyclin dependent kinase inhibitor p21(WAF1/Cip1) (Cdkn1a). Six-week-old male mice were divided into 4 groups of 6 mice each, housed in groups of 3 per cage. After 1 week mice were intraperitoneally injected with STZ. Mice (n=6) in the untreated control group did not receive any treatment. After 1 week, 18 mice showing non-fasting blood glucose levels of 230-400 mg/dL were divided into 3 groups: one group was fed with AIN93G only (control group), the others with an AIN93G diet containing 0.1% or 0.5% quercetin (Funakoshi, Tokyo, Japan) for 2 weeks.
