Synergistic activation of p53 by inhibition of MDM2 expression and DNA damage.
The MDM2 oncogene encodes an inhibitor of the p53 tumor suppressor protein that regulates p53 in a negative feedback loop. MDM2 gene amplification and overexpression occur in several types of tumors and are often associated with poor prognosis. An MDM2 antisense phosphorothioate oligodeoxynucleotide has been identified that effectively inhibits MDM2 expression in tumor cells containing MDM2 gen...

Background and Objective: The use of low-molecular-weight, nonpeptidic molecules that degrade the interaction between the p53 protein and its negative regulator MDM2 (Murine- double minute colon 2) is a new therapeutic strategy for treatment of various types of cancer. One of these agents is RITA (reactivation of p53 and induction of tumor cell apoptosis) which binds to p53 protein and inhibits...
متن کاملUbiquitous induction of p53 in tumor cells by antisense inhibition of MDM2 expression.
BACKGROUND The MDM2 oncogene functions as a negative feedback regulator of the p53 tumor suppressor. Abnormal expression of MDM2 in tumors may attenuate the p53-mediated growth arrest and apoptosis response, resulting in increased cell proliferation and resistance to chemotherapy. MATERIALS AND METHODS We have developed phosphorothioate antisense oligodeoxynucleotides optimized for inhibition...
متن کاملThe Role of Tumor Protein 53 Mutations in Common Human Cancers and Targeting the Murine Double Minute 2–P53 Interaction for Cancer Therapy
The gene TP53 (also known as protein 53 or tumor protein 53), encoding transcription factor P53, is mutated or deleted in half of human cancers, demonstrating the crucial role of P53 in tumor suppression. There are reports of nearly 250 independent germ line TP53 mutations in over 100 publications. The P53 protein has the structure of a transcription factor and, is made up of several domains. T...
متن کاملCancer-mutated ribosome protein L22 (RPL22/eL22) suppresses cancer cell survival by blocking p53-MDM2 circuit
Several ribosomal proteins (RPs) in response to various ribosomal stressors have been shown to play a critical role in p53-dependent regulation of cell cycle arrest, apoptosis and tumor suppression. Here, we report ribosomal protein L22 (RPL22/eL22) as a novel p53 activator highly mutated (mostly deletion mutation) in various types of human cancers, but not essential for ribosomal biogenesis in...
