Activation of oncoproteins and inactivation of tumor suppressors induces tumorigenesis. When these events happen upstream of pRb and p53, cancer therapies may initially succeed and then fail when pRb and p53 are activated and then re-inactivated. Therapies might succeed if they remain effective when pRb and p53 are genetically inactivated.

Synephrine, a protoalkaloid found in Citrus aurantium (CA) peels, exerts lipolytic, anti-inflammatory, and vasoconstrictive effects; however, its antioxidant activity remains unclear. In this study, electron spin resonance spectroscopy revealed that synephrine scavenged both hydroxyl and superoxide anion radicals. Several external stimuli, such as HO, X-rays, and ultraviolet (UV) radiation, cause stress-induced premature senescence (SIPS).

In almost all cancers, the p53 pathway is disabled and cancer cells survive. Hence, it is crucially important to induce cell death independent of p53 in the treatment of cancers. The transcription factor E2F1 is controlled by binding of the tumor suppressor pRB, and induces apoptosis by activating the gene, an upstream activator of p53, when deregulated from pRB by loss of pRB function.
