Description
Reactivation of p53 and induction of tumor cell apoptosis (RITA) is an activator of p53 that exhibits anticancer chemotherapeutic and anti-angiogenic activities. In vivo, RITA downregulates expression of VEGF, HIF-1α, p21, and HDM2. In cellular and animal models of neuroblastoma, RITA inhibits expression of N-Myc, AurK, Mcl-1, Bcl-2, MDM2, and MDMX, inducing apoptosis and inhibiting growth. Similar effects are observed in models of gastrointestinal stromal tumors and cervical carcinoma.
