ABSTRACT: Hypercholesterolemai is a major contributor to atherosclerosis development. To assess the effects of hypercholesterolemia on the transcriptional profiling in foam cells, mice were fed regular chow, or WD for 2 or 14 weeks prior to sacrifice. We used microarrays for broad analysis of gene expression in the 3 experimental groups. Each group included 5 mice. ApoE-/- mice were fed regular mouse chow to the age of 22 weeks (CHOW) or a western-type diet for 2 weeks between weeks 22 and 24 (2w-WD) or for 14 weeks between weeks 8 and 22 (14w-WD). Foam cells in cross-sections of the aourtic sinus were isolated by laser-capsure microdissection (n=5 per group). RNA was amplified by in vitro transcription, biotinylated, and hybridized to Affymetrix Mouse Genome 430 2.0 Arrays.

Project description:Male C57Bl/6J mice were fed 45%kcal fat diet (HF) or regular rodent chow (NC) from 4 weeks to 16 weeks of age. Gene expression was compared between RNA obtained from pancreatic islets of HF fed mice and NC mice.
Project description:Male and female mice (Bl6/J) were fed a chow diet (control 1 and control 2) or a High fat diet (HFD) or a Choline deficient High fat diet (CD HFD) or a Western Diet (WD) or a Western Diet supplemented with glucose and fructose in drinking water (WD glucose fructose) for 15 weeks.
Project description:We propose comparing liver gene expression of WT and female ERKO mice early in the high-fat feeding period to animals fed a regular chow diet. Analyzing liver tissue before the fatty liver disease phenotype becomes severe will allow identification of target genes which may be causal. Comparison of regular chow fed WT animals to high fat fed WT animals will allow for identification of hepatic genes up-regulated in response to high fat feeding. Comparison of regular chow fed WT animals to regular chow fed ERKO animals will help clarify hepatic gene expression patterns that may be implicated in increased susceptibility to weight gain and glucose intolerance. Comparison of high fat fed WT animals to high fat fed ERKO animals will provide insight into genes that could be implicated in leading to increased fat accumulation in the liver over time during high fat feeding. Finally, comparison of regular chow fed ERKO animals to high fat fed ERKO animals will help identify genes that may be contributing to increased liver fat accumulation in response to high fat feeding in these animals.
Project description: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.
Project description:Male Wistar rats weighing 90-120 g were acclimatized for one week and fed standard laboratory chow, at which time the animals were divided into two groups. Animals were then pair-fed for 8 weeks a regular laboratory chow and water “ad libitum” or Lieber-DeCarli diet (36% calories from ethanol). Control animals received the iso-caloric amount of dextrose to replace ethanol. After 8 weeks of differential feeding rats were euthanized, the pancreas immediately dissected and stored at -80?C until RNA isolation. RNA expression was analyzed using Affymetrix RAE230A gene chips Keywords: stress response, disease state analysis
Project description:To get further insights into the processes leading to attenuation of early stage atherosclerosis in the bortezomib treated LDLR-KO mice, microarray profiling of gene expression was performed on RNA taken from whole aortae of bortezomib treated LDLR-KO and sham- treated LDLR-KO mice fed a Western diet for 6 weeks and compared the changes in gene expression in both groups to non-atherosclerotic CD animals. Male 10-week-old LDLR-KO mice (B6.129S7-Ldlrtm1Her/J; JAX Mice, Boston) were fed a Western-type diet for 6 weeks ad libitum and received intraperitoneal injections of bortezomib (50 µg/kg body weight; WD+Bor) or saline (WD) twice weekly (n = 4). Mice that were fed normal diet served as chow diet control (CD; n = 4). Gene expression in aortic tissue was measured. Two independent experiments were performed.
Project description:Hepatic transcriptome of junctional adhesion molecule A knockout, F11r–/– mice fed a Western diet (WD) for eight weeks. A cohort of WD-fed mice were treated with IgG or α4β7 mAb for four weeks starting at week four following initiation of the WD.
Project description:Transcriptional profiling of WAT comparing wild-type control with Ahnak Knockout mice fed regular chow and high fat diet We obtained white adipose tissue from mice fed regular chow and high fat diet for Affymetrix microarrays
