Project description:We demonstrate that conjugated linoleic acid (CLA), when given to mice as a dietary supplement, induced an enlarged liver and hepatic steatosis. The progression of NAFLD and insulin resistance was reversed by GW6471 a small-molecule antagonist of PPARα. Transcriptional profiling of livers unraveled that genes involved in lipid metabolism core gene programs controlled by PPARα in response to CLA and GW6471.Our findings reveal a novel role of PPARα in the regulation of lipid homeostasis and highlight its druggable nature in NAFLD.

Project description:Conjugated linoleic acid (CLA), a class of fatty acids found in beef and dairy products, has been shown to inhibit tumorigenesis in a variety of cancer model systems. Based on previously well-documented anti-tumor activity of CLA in rodent models of breast cancer, a pilot study was initiated to examine the effect of dietary CLA in a well-established transgenic model of breast cancer. Western blots were performed for the detection of AKT, c-Src, ERK1/2, and Cdc24. CLA significantly increased tumor burden (p<0.1) independent of an increase in oncogenic signaling. Mammary gland whole mounts indicated a loss of mammary adipose and extensive epithelial expansion in CLA-treated animals. Microarray analysis indicated a significant reduction in cytoskeletal related genes with at least a two-fold decrease in five out of six CLA-fed animals compared to untreated controls. Reduction of Cdc42, a key regulator of cell adhesion and cytoskeletal arrangements, was confirmed at the protein level by western blot (p<0.01). These findings suggest that dietary CLA may advance the malignant phenotype by promoting a loss of cell polarity and adhesion in the mammary gland epithelium. This action may have serious clinical implications for a subset high-risk population and warrants further investigation.

This action may have serious clinical implications for a subset high-risk population and warrants further investigation. Virgin, four-week-old PyV-mT mice were administered a diet of a mixed-isomer CLA formulation (1% wt/wt) (N=6) or control AIN96G diet (N=5) for four weeks. Measurements of food disappearance, weights and palpations were recorded weekly. All animals were euthanized at eight weeks of age. Formalin-fixed, paraffin-embedded mammary gland tissue was used for H&E and trichrome staining and immunohistochemistry for Ki67. Tissue levels of CLA were measured by gas chromatography. Thoracic mammary glands were fixed in glacial acetic acid:ethanol and carmine stained. cDNA microarray was performed on RNA from 6 CLA-fed mice and 4 control mice using the Affymetrix 430 2.0 mouse genome chips.
