Background: Apoptosis is a regular program of cell death. This active form of cell death is characterized by morphological changes such as cell wrinkling, chromatin condensation and DNA fragmentation. The purpose of this study was to determine the effect of Resistance training along with nano-curcumin supplementation on p53(Protein53)-p21(Protein53) axis and TERF2 (Telomeric repead-binding factor 2) gene expression in the muscle tissue of male Wistar rats.
