The present study was carried out to understand the therapeutic effect of curcumin (CUR) against stroke in the experimental animal model. The study investigates the healing effect of CUR on mitochondrial dysfunction and inflammation.Male albino, Wistar strain rats were used for the induction of middle cerebral artery occlusion (MCAO), and reperfusion. Enzyme-linked immunosorbent assay (ELISA) was used for the determination of interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) in the brain region. Western blot analysis was used to determine the protein expression levels of Bax, Bcl-2, p53, and Sirt1.The water level was determined in brain region by using standard method. Experimental results indicated that the use of CUR significantly reduced brain edema and water content. IL-6 and TNF-α were significantly reduced in the brain region following use of CUR. Mitochondrial membrane potential (MMP) also reduced significantly after CUR treatment. Protein expression of p53 and Bax were significantly reduced, whereas Bcl-2 and Sirt1 were increased following CUR treatment.Taking all these data together, it is suggested that the use of CUR may be a potential therapeutic agent for the treatment of stroke.
