N-Acetylcysteine Inhibits Lipids Production in Mature Adipocytes through the Inhibition of Peroxisome Proliferator-Activated Receptor
International Journal of Biochemistry Research & Review,
Aims: Reports regarding the effects of antioxidants in obesity have been contradictory. Antioxidant N-acetylcysteine is usually considered a nutritional supplement. Our aim is to evaluate bioactivity of N-acetylcysteine (NAC) on mature adipocytes, which is a close model to in vivo condition.
Study Design: In vitro study.
Place and Duration of Study: Department of Basic Science (Universidad Nacional de Lujan), Department of Chemical Biology (Universidad de Buenos Aires), CONICET – INEDES and CONICET – IQUIBICEN, between March 2017 and June 2019.
Methodology: We evaluated the bioactivity of different concentrations of NAC for 5 days (0.01 mM to 5 mM) on fully differentiated 3T3-L1 cells (mature adipocytes).
Results: We demonstrated that NAC treatment was not toxic to mature adipocytes. Only 5mM NAC inhibited reactive oxygen species production. 5 mM NAC treatment resulted in a 60% decrease in cellular triglycerides content and inhibited 70% cholesterol accumulation. We also determined the mRNA and protein expression levels of Peroxisome Proliferator-Activated Receptor g as well as, mRNA levels of lipid protein Perilipin in NAC treated adipocytes; we observed that 5mM NAC treatment caused nearly 30% decrease in the expression of these parameters.
Conclusion: These results suggest that NAC could avoid lipid accumulation in mature adipocytes; the antioxidant NAC could be beneficial in obesity treatment.
