ABSTRACT: Gene expression in livers of male wild-type (WT) and OGG1-deficient (Ogg1-/-) mice fed either a chow diet or a high-fat diet (HFD) were examined. Mice were fed the diet for 10 weeks prior to tissue collection and were 22 weeks of age at the time of tissue collection. 24 Total samples were analyzed. We generated the following pairwise comparisons using GeneSifter: WT Chow vs Ogg1-/- Chow; WT HFD vs. Ogg1-/- HFD using t-test followed by Benjamini and Hochberg correction. An adjusted p-value less than 0.05 was considered to be statistically significant.

Project description:To identify molecular mechanism underlying the protection from diet-induced hepatic steatosis in AHNAK deficiency mice, we examined microarray analysis with liver sample from HFD-fed AHNAK KO and WT mice. Two-condition experiment, regular chow (CD) -fed WT vs. CD-fed AHNAK KO and High fat diet(HFD)-fed WT vs. HFD-fed AHNAK KO mice. Biological replicates: 3 control, One replicate per array.
Project description:Obesity is tightly associated with an increased risk of nonalcoholic fatty liver disease (NAFLD). However, the molecular mechanisms of obesity-induced fatty liver remain largely unknown.In order to identify genes that are potentially involved in dysfunctional hepatic lipid homeostasis in obesity, we performed a clustering analysis of Affymetrix arrays,which revealed that a number of mRNAs were dys-regulated in the livers of mice fed a high-fat diet (HFD), compared with mice fed a normal chow diet (ND). To identify genes that are potentially involved in dysfunctional hepatic lipid homeostasis in obesity, male C57BL/6 mice aged 8 weeks were fed a normal diet (ND) or high-fat-diet (HFD) containing 60 Kcal% of fat for 12 weeks. Then mice were sacrificed and total RNAs were isoloated from hepatic tissues. Affymetrix array hybridisation and scanning were performed using Mouse Genome 430 2.0 chips.Total RNA samples obtained from six mice per group (ND and HFD) and pooled by each of the two were used for microarray analysis.
Project description:The purpose of this study was to investigate whether paternal high-fat diet (HFD) transgenerationally remodeled the hepatic transcriptome of F2 female rats Liver mRNA expression profiling of F2-female from F0-founders fed either a chow or a chronic HFD challenged. Adult females were challenge or not a high-fat diet for 12 weeks. Liver was dissected at an endpoint experiment. Rats were subjected to 4 hours fasting prior to anesthesia with pentobarbital and tissue collection.
Project description:The purpose of this study was to investigate whether grandpaternal high-fat diet (HFD) transgenerationally remodels the transcriptome of skeletal muscle EDL muscle mRNA expression profiling of F2-female offspring from F0-founders fed either a chow or a chronic HFD challenged. Adult females were challenge or not a high-fat diet for 12 weeks. EDL muscle was dissected at an endpoint experiment. Rats were subjected to 4 hours fasting prior to anesthesia with pentobarbital and tissue collection.
Project description:High dietary fat intake is a major risk factor for the development of obesity, which is frequently associated with diabetes. To identify genes involved in diabetic nephropathy, GeneChip Expression Analysis was employed to survey the glomerular gene expression profile in diabetic KK/Ta mice fed with a high-fat diet (HFD). Isolated glomeruli from three 20-week-old KK/Ta mice fed with HFD (HFD group) or a normal fat diet (Chow group) were dissected. Total RNA was extracted and labeled for hybridization using the Affymetrix GeneChip Mouse Genome 430 2.0 Array. The gene expression profile was compared between the HFD and Chow groups using GeneSpring 7.3.1 software.
Project description:The purpose of this study was to investigate whether paternal high-fat diet (HFD) transgenerationally remodels the epigenome of spermatozoa to alter metabolism in the F1 and F2 generation offspring White adipose tissue mRNA expression profiling of F2-female offspring from F0-founders fed either a chow or a chronic HFD challenged. Adult females were challenged or not a high-fat diet for 12 weeks. White adipose tissue was dissected at an endpoint experiment. Rats were subjected to 4 hours fasting prior to anesthesia with pentobarbital and tissue collection.
Project description:Obesity is a well-known public health issues and calorie restriction (CR) is an effective intervention. Here, we subjected mice to chow diet or high fat diet (HFD), and later mice with HFD-induced obesity switched to CR.
