We propose that the antioxidant function of P53 represent an important component of its suppressor activity, which decreases probability of genetic alterations and assists the survival and repair of cells with minor cellular injuries.Also, the findings of our study can be assisted by the reports proved the P53-dependent enhancement of interferon regulatory factor (IFN) signaling and other genes involved in innate immunity including IRF5, antiviral genes such as ISG15 and double stranded RNA (dsRNA)-activated protein kinase R(PKR), and pro-inflammatory chemokines such as monocyte chemoattractant protein 1 (MCP-1)
