The Effects of Phytosterols Intake on Systematic and Tissue Specific Lipid Metabolism in C57BL/6J Mice

ABSTRACT: Purpose: To investigate the effects of phytosterols intake on systematic and tissue specific lipid metabolism in C57BL/6J mice. Methods: Healthy male C57BL/6J mice were randomly divided into control diet group (CS) and phytosterols diet group (PS, 2% phytosterols). After 28 weeks of continuous feeding, livers, lungs were collected for RNA-seq analysis. All samples were paired-end sequenced on the Illumina HiSeq PE150 platform. The sequence reads that passed quality filters were analyzed at the transcript isoform level. RT–qPCR validation was performed using SYBR Green assay. Results: We mapped about 40 million sequence reads per sample to the mouse genome and identified 23,138 transcripts in the liver and 26,388 transcripts in the lung. Approximately 10% of the transcripts showed differentially expressed in the liver and lung between the two dietary groups, with a fold change ≥1.5 and p <0.05. Enrichment analysis revealed changes in lipid metabolic pathways. RT-qPCR confirmed the changes in related genes. Conclusions: Phytosterols supplementation effected tissue specific lipid metabolic regulation in the liver and lung. RNA-seq provided us with data at the transcriptome level in the liver and lung of mice.

Bone marrow TTP deficeincy significantly increased inflammation while reduced plasma lipid and hepatic steatosis in LDLR knockout mice

Project description:In order to examine the effects of bone marrow TTP deficiency on inflammation and lipid metabolism and determine the driving force during atherosclerosis, 8 week-old female LDLR−/− mice on C57BL/6J background were lethally irradiated and reconstituted with a wild type (TTP+/+) or TTP knockout (TTP−/−) bone marrow cells and fed a Western diet for 12 weeks. Then mice were sacrificed and tissues were collected for analysis. Liver tissues were collected and gene expression was analysed using a whole genome microarray. Bone marrow TTP−/− recipients displayed a significantly higher systemic and multi-organ inflammation compared to the BM-TTP+/+ recipients. BM-TTP−/− mice displayed a significant reduction of serum lipid levels, attenuated hepatic steatosis, and decreased lipid excretion than the control mice. microarray data showed that BM-TTP deficiency modulate liver genes involved in lipid metabolism and inflammatory response. RT-qPCR was used to confirm the results in several genes from microarray data. BM-TTP deficiency did not further accelerate atherorogenesis process in LDLR−/− mice after a Western diet feeding. TTP promoted VLDL to drive proinflammatory mechanism into proatherogenic mechanism.

Hepatic transcriptomics of squalene in male Apoe-deficient mice on Western diet

Project description:Background and Purpose: Squalene is the main hydrocarbon present in extra virgin olive oil and it has been reported to have anti-steatotic properties in different animal models. The aims of this study were to investigate its effects on liver transcriptomics in Male C57BL/6J Apoe-deficient mice. Experimental Approaches: Male C57BL/6J Apoe-deficient mice were fed a purified Western diet with or without squalene during 11 weeks and hepatic squalene content was assessed. Hepatic transcriptomic changes were studied and confirmed by RT-qPCR. Key Results: Squalene supplementation increased its hepatic content. The Cyp2b10 and Cyp2c55 gene expressions were significantly up-regulated by the squalene intake in all animal models, with independence of sex, sexual hormones, dietary fat content, genetic background and dose, and were strongly associated with antioxidant defense capacity and with lipid content and composition. Conclusions and Implications: hepatic squalene exerts its activity through overexpression of these cytochromes and their changes in virgin olive oil diets may be due to squalene.

transcription profiling by array of C57BL/6J mice fed a Western-style diet with or without 0.05% quercetin against mice on a control diet to study the effect of quercetin on obesity and hepatic gene expression

Project description:To determine the effect of consumption of a quercetin-rich diet on obesity and dysregulated hepatic gene expression, C56BL/6J mice were fed for 20 weeks on control or a Western diet high in fat, cholesterol and sucrose, both with or without 0.05% quercetin. Chronic dietary intake of quercetin reduced body weight gain and visceral and liver fat accumulation, and improved hyperglyceamia, hyperinsulinaemia, dyslipidaemia in mice fed a Western-style diet. Feeding a Western-style diet altered expression of genes related to inflammatory responses, lipid metabolism and oxidative phosphorylation in C57BL/6J mice after 20 weeks. The results from exhaustive gene expression analysis showed that quercetin minimally influenced hepatic gene expression in mice fed the Western diet. The gene screening results (GSEA) were consistent with the notion that it did improve mitochondrial function to some extent. Quantitative RT-PCR analysis indicated that quercetin did influence important regulators of fat accumulation and metabolic disorders. Our results suggest that quercetin reduces fat accumulation presumably through decreasing oxidative stress and increasing PPARα expression, and the following improvement of gene expression related to steatosis in the liver. C56BL/6J mice were fed for 20 weeks on AIN93G (con) or a Western diet high in fat, cholesterol and sucrose, both with or without 0.05% quercetin for 20 weeks.
