Abstract:
To investigate the effect of Mucuna pruriens (Linn) ethanol extracts (MPEE) on glucose and lipid metabolism in insulin resistance 3T3-L1 adipocytes. The insulin resistance 3T3-L1 adipocyte model was induced by DMEM medium containing high concentration of glucose and insulin. The levels of glucose consumption, free fatty acid (FFA), glycerol, cellular triglyceride(TG), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the culture medium were determined by commercial assay kits after the cells treated with different concentrations of MPEE for 24 h. The mRNA expression levels of glucose transporter-4 (GLUT-4), hormone-sensitive triglyceride lipase(HSL) and inflammation related factors [including TNF-α, IL-6, monocyte chemotactic protein-1 (MCP-1) and C-reaction protein (CRP)] in cells were determined by Quantitative real-time PCR (qRT-PCR) assay. MPEE could enhance the glucose consumption, decrease the cellular TG levels and reduce the releasing of FFA and glycerol in insulin resistance cells. MPEE also reduced the secretion of TNF-α and IL-6, and reduced the mRNA expressions of inflammation mediators (including TNF-α, IL-6, MCP-1 and CRP) in model cells. In addition, MPEE was able to up-regulate the mRNA levels of GLUT-4, and reduce the mRNA levels of HSL in insulin resistance cells. These results suggested that the MPEE treatment was able to regulate the glucose and lipid metabolism to against the insulin resistance via increasing the glucose consumption, enhancing the TG lipolysis, and reducing the releasing of FFA and glycerol in 3T3-L1 adipocytes. MPEE treatment also down-regulated the inflammation levels by reducing the secretion of inflammatory mediators.
