Project description:We performed a systemic study of the poloxamer P-407-induced chronic hyperlipidemia in C57BL/6J mice. Mice were treated 96 days every third day.The poloxamer mostly elevates plasma triglycerides and cholesterol while change of the liver cholesterol is not significant. Experiment Overall Design: A group of 12 mice were administered 0.5 g/kg poloxamer P-407 by intraperitoneal (i.p.) injection (poloxamere group), a control group of 4 mice were injected every third day with normal saline. Total RNA from P-407 treated 12 mice has been pooled into 3 biological replicas (Smpl1, Smpl2 and Smpl3). Reference total RNA has been obtained by pooling 4 mice from control group. Each RNA sample has been splitted and hybridised in parallel on cDNA (G4104A) and oligonucleotide (G4120A) mouse microarrays (Agilent Technologies, CA, USA.

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons. RNA sample was taken from liver of 3-week-old mouse prenatally received high-fat diet prior to pregnancy, during pregnancy and lactation, or through prior to and during pregnancy and lactation, while control RNA was taken from control counterpart prenatally received normal diet alone. Comparisons among groups were made by one-color method with normalized data from Cy3 channels for data analysis.

Project description:High fat diets are known to be a risk factor for prostate cancer. In this study, we investigated the effect of high fat diet on mouse prostate gene expression. C57BL/6J mice were fed either a control or high fat diet for 12 weeks. Microarray analyses were performed on mouse ventral prostate (VP) and dorsolateral prostate (DLP), followed by canonical pathway analysis and regulatory network identification. mRNA changes were confirmed by real time PCR. Approximately 2,125, and 1,194 genes responded significantly to the high fat diet in VP, DLP, respectively. Pathways and networks related to oxidative stress, glutathione metabolism, NRF-mediated oxidative stress response and NF-kappaB were all differentially regulated by high fat diet. GPx3 mRNA levels were decreased by approximately 2-fold by high fat diet in all 3 prostate lobes. In human non-transformed prostate cells (PrSC, PrEC and BPH-1), cholesterol loading decreased GPx3 expression, and increased H2O2 levels of culture medium. Troglitazone increased GPx3 expression in 3 normal prostate cells, and decreased H2O2 levels. In addition, troglitazone attenuated cholesterol-induced H2O2 increase. Tissue from prostate cancer biopsies had decreased GPx3 mRNA and its level was inversely related to the Gleason score. High fat diet alters pathways related to many genes concerned with oxidative stress. GPx3, a gene identified by this analysis, was found to be down regulated by high fat diet and appears be decreased in human prostate cancers, suggesting that GPx3 may have a possible role in modulating carcinogenesis. Control group:5 C57BL/6J mice (Taconic, Hudson, NY), 8-weeks of age, fed control diet ad libitum for 12 weeks; Experimental group: 5 C57BL/6J mice (Taconic, Hudson, NY), 8-weeks of age, fed ad libitum high fat diet for 12 weeks.

Project description:Study designed to identify genes that are induced in both BAT and skeletal muscle during acute adaptive thermogenesis in mouse using gene expression microarray. Animal studies were performed under approved UCLA animal research protocols and according to guidelines established in the Guide for Care and Use of Laboratory Animals. C57BL/6J mice were maintained in 12-h light/dark conditions and fed a regular chow diet (Purina 50010, Lab Diet, USA). Cold exposure was performed as described. After euthanasia, tissues were collected and frozen until use. Total RNA was isolated from mouse tissues by extraction with TRIzol from either brown adipose tissue (BAT) or skeletal muscle (quadriceps) after exposure to cold (4 degrees C for 4 hours). The mice were of the C57BL/6J strain and were maintained in 12-h light/dark conditions and fed a laboratory chow diet that consisted of 4.5% fat, 50% carbohydrate by weight (Lab Diet, Purina 50010).

Project description:We studied the effect of dietary fat type, varying in polyunsaturated/saturated fatty acid ratio's (P/S) on development of metabolic syndrome. C57Bl/6J mice were fed purified high-fat diets (45E% fat) containing palm oil (HF-PO; P/S 0.4), olive oil (HF-OO; P/S 1.1) or safflower oil (HF-SO; P/S 7.8) for 8 weeks. A low-fat palm oil diet (LF-PO; 10E% fat) was used as a reference. Additionally, we analyzed diet-induced changes in gut microbiota composition and mucosal gene expression. The HF-PO diet induced a higher body weight gain and liver triglyceride content compared to the HF-OO, HF-SO or LF-PO diet. In the intestine, the HF-PO diet reduced microbial diversity and increased the Firmicutes/Bacteroidetes ratio. Although this fits a typical obesity profile, our data clearly indicate that an overflow of the HF-PO diet to the distal intestine, rather than obesity itself, is the main trigger for these gut microbiota changes. A HF-PO diet-induced elevation of lipid metabolism-related genes in the distal small intestine confirmed the overflow of palm oil to the distal intestine. Some of these lipid metabolism-related genes were previously already associated with the metabolic syndrome. In conclusion, our data indicate that saturated fat (HF-PO) has a more stimulatory effect on weight gain and hepatic lipid accumulation than unsaturated fat (HF-OO and HF-SO). The overflow of fat to the distal intestine on the HF-PO diet induced changes in gut microbiota composition and mucosal gene expression. We speculate that both are directly or indirectly contributive to the saturated fat-induced development of obesity and hepatic steatosis. Keywords: Diet intervention study Nine-week-old C57Bl/6J mice were fed a low-fat diet (LF-PO) and three different types of high-fat diet, based on palm oil (HF-PO; P/S1.0), olive oil (HF-OO; P/S4.6) and safflower oil (HF-SO; P/S10.1) for 8 weeks. Body weight was recorded weekly and after 7 weeks of diet intervention an oral glucose tolerance test was performed. After 2 weeks of diet intervention, 6 mice per high-fat diet group were anaesthetized with a mixture of isofluorane (1.5%), nitrous oxide (70%) and oxygen (30%) and the small intestines were excised. Adhering fat and pancreatic tissue were carefully removed. The small intestines were divided in three equal parts along the proximal to distal axis (SI 1, SI 2 and SI 3) and microarray analysis was performed on mucosal scrapings.

Project description:Time-course analysis of adipocyte gene expression profiles response to high fat diet. The hypothesis tested in the present study was that in diet-induced obesity, early activation of TLR-mediated inflammatory signaling cascades by CD antigen genes, leads to increased expression of pro-inflammatory cytokines and chemokines, resulting in chronic low-grade inflammation. Early changes in collagen genes may trigger the accumulation of ECM components, promoting fibrosis in the later stages of diet-induced obesity. New therapeutic approaches targeting visceral adipose tissue genes altered early by HFD feeding may help ameliorate the deleterious effects of a diet-induced obesity. Total RNA obtained from isolated epididymal and mesenteric adipose tissue of C57BL/6J mice fed normal diet or high fat diet for 2, 4, 8, 20 and 24weeks
