Mexican Ganoderma lucidum extracts decrease lipogenesis modulating transcriptional metabolic networks and gut microbiota in C57BL/6 mice fed with a high-cholesterol diet from early Drosophila embryo

Project description:Background: Prevention of hyperlipidemia and associated diseases is a health priority. Complementary medicine based on scientific evidence has recently recognized the potential of natural products for modulating lipid metabolism, such as the medicinal mushroom Ganoderma lucidum (Gl), which possesses hypocholesterolemic, prebiotic and antidiabetic properties. Methods: Whole-transcriptomic changes in liver and kidney from a mouse model (C57BL/6), under a high-cholesterol diet and standardized Gl extracts (Gl-1, Gl-2) or simvastatin administration, were analyzed to determine Gl hypocholesterolemic activity. Further effects of Gl extracts on lipid metabolism were evaluated using an in vitro hepatic-like macrophage model. Additionally, correlations among hepatic gene expression, microbiota and serum lipid profiles in vivo established by Gl extracts were evaluated. Results: Based on the hepatic and renal mRNA profiles of mice treated with Gl extracts and high-cholesterol diet, we identified relevant metabolic pathways modulated by Gl involving the restriction of lipid biosynthesis and the enrichment of lipid degradation and secretion. We further showed that Gl extracts induce a significant decrease of macrophage lipid storage and cholesterol biosynthesis, which occurs concomitantly by the down-modulation of Fasn and Elovl6. We also determined that prebiotic effects of Gl extracts modulating gut microbiota are correlated with the gene expression portraits. Conclusions: Our high-throughput analysis allowed to identify key transcriptomic nodes established by Gl extracts and their interaction with microbiome composition related to lipid catabolic signaling. Our results indicated that our Gl extracts have a robust potential to be used as transcriptome modulators and prebiotic agents to prevent metabolic disorders associated to hypercholesterolemia.
