Abstract

Background and Aim: SIRT1 and PGC1α are two important genes which play critical roles in regulating oxidative stress and inflammation processes. The aim of this study was to assess the effects of omega 3 and vitamin E supplement co-administration on SIRT1 and PGC1α gene expression and serum levels of antioxidant enzymes in CAD patients. Methods and Results: Participants of this randomized controlled trial included 60 CAD male patients who received omega 3 (4g/day) and vitamin E placebo (OP), omega 3 (4g/day) and vitamin E (400IU/day) (OE) or omega 3 and vitamin E placebos (PP) for two months. Gene expression of SIRT1 and PGC1α in Peripheral Blood Mononuclear Cells (PBMCS) was assessed using RT-PCR. Furthermore, serum antioxidant enzymes and hsCRP were assessed at the beginning and the end of the intervention. Gene expression of SIRT1 and PGC1α increased significantly in OE group (P =0.039 and P= 0.050, respectively). Catalase and hsCRP increased significantly in OE and OP groups. GPX and SOD did not statistically change in all groups. TAC increased significantly in OE group (P=0.009), but not in OP and PP groups. Conclusion: Combination of omega 3 fatty acids with vitamin E may have beneficial effects on CAD patients by increasing gene expression of SIRT1 and PGC1α and improving oxidative stress and inflammation in these patients. Keywords: CAD, omega 3, vitamin E, SIRT1, PGC1α, antioxidant enzymes
