Colon Transcriptome is Modified by a Dietary Pattern/Atorvastatin Interaction in the Ossabaw Pig

Project description:Overall diet quality and statin therapy are important modulators of inflammation and CAD progression, yet their effects on colon is not well understood. Our objective was to examine the effects and interaction of dietary patterns and statin therapy on colonic mucosa gene expression in the Ossabaw pig.

Colon transcriptome is modified by a dietary pattern/atorvastatin interaction in the Ossabaw pig.

Project description:Optimizing diet quality in conjunction with statin therapy is currently the most common approach for coronary artery disease (CAD) risk management. Although effects on the cardiovascular system have been extensively investigated, little is known about the effect of these interventions in the colon and subsequent associations with CAD progression. To address this gap, Ossabaw pigs were randomly allocated to receive, for a six-month period, isocaloric amounts of either a heart healthy-type diet (HHD; high in unrefined carbohydrate, unsaturated fat, fiber, supplemented with fish oil, and low in cholesterol) or a Western-type diet (WD; high in refined carbohydrate, saturated fat and cholesterol, and low in fiber), without or with atorvastatin therapy. At the end of the intervention period, colon samples were harvested, mucosa fraction isolated, and RNA sequenced. Gene differential expression and enrichment analyses indicated that dietary patterns and atorvastatin therapy differentially altered gene expression, with diet-statin interactions. Atorvastatin had a more profound effect on differential gene expression than diet. In pigs not receiving atorvastatin, the WD upregulated "LXR/RXR Activation" pathway compared to pigs fed the HHD. Enrichment analysis indicated that atorvastatin therapy lowered inflammatory status in the HHD-fed pigs, whereas it induced a colitis-like gene expression phenotype in the WD-fed pigs. No significant association was identified between gene expression phenotypes and severity of atherosclerotic lesions in the left anterior descending-left circumflex bifurcation artery. These data suggested diet quality modulated the response to atorvastatin therapy in colonic mucosa, and these effects were unrelated to atherosclerotic lesion development.

A Western-type dietary pattern and atorvastatin induce epicardial adipose tissue interferon signaling in the Ossabaw pig.

Project description:Epicardial adipose tissue (EAT) inflammation is thought to potentiate the development of coronary artery disease (CAD). Overall diet quality and statin therapy are important modulators of inflammation and CAD progression. Our objective was to examine the effects and interaction of dietary patterns and statin therapy on EAT gene expression in the Ossabaw pig. Pigs were randomized to 1 of 4 groups; Heart Healthy diet (high in unsaturated fat, unrefined grain, fruits/vegetables [HHD]) or Western diet (high in saturated fat, cholesterol, refined grain [WD]), with or without atorvastatin. Diets were fed in isocaloric amounts for 6 months. A two-factor edge R analysis identified the differential expression of 21 genes. Relative to the HHD, the WD resulted in a significant 12-fold increase of radical s-adenosyl methionine domain containing 2 (RSAD2), a gene induced by interferon signaling. Atorvastatin led to the significant differential expression of 17 genes predominately involved in interferon signaling. Results were similar using the Porcine Translational Research Database. Pathway analysis confirmed the up-regulation of interferon signaling in response to the WD and atorvastatin independently. An expression signature of the largely interferon related differentially expressed genes had no predictive capability on a histological assessment of atherosclerosis in the underlying coronary artery. These results suggest that a WD and atorvastatin evoke an interferon mediated immune response in EAT of the Ossabaw pig, which is not associated with the presence of atherosclerosis.

Monocyte gene expression profiling in familial combined hyperlipidemia and its modification by atorvastatin treatment

Project description:Introduction: The genetic origin of familial combined hyperlipidemia (FCH) is not well understood. We used microarray profiling of peripheral blood monocytes to search novel genes and pathways involved in FCH. Methods: Fasting plasma for determination of lipid profiles, inflammatory molecules, and adipokines was obtained and peripheral blood monocytes were isolated from male FCH patients basally and after 4 weeks of atorvastatin treatment. Sex-, age- and adiposity-matched controls were also studied. Gene expression profile was analyzed using Affymetrix Human Genome U133A 2.0 GeneChip arrays. Results: Analysis of gene expression by cDNA microarrays showed that 82 genes were differentially expressed in FCH monocytes compared to controls. Atorvastatin treatment modified the expression of 87 genes. Changes in the expression of some genes, confirmed by real time RT-PCR, (CD36, leucine-rich repeats and immunoglobulin-like domains-1, tissue factor pathway inhibitor 2, myeloid cell nuclear differentiation antigen tumor necrosis factor receptor superfamily, member 25 and CD96) may be related to a proinflammatory environment in FCH monocytes, which is partially reversed by atorvastatin. Higher plasma levels of triglycerides and free fatty acids and lower levels of adiponectin in FCH patients could also trigger changes in gene expression that atorvastatin cannot modify. Conclusions: Our results demonstrate clear differences in gene expression in FCH monocytes compared with those of matched healthy controls, some of which are influenced by atorvastatin treatment. Keywords: comparative study differential gene expression
