Mechanisms of p53 Functional De-Regulation: Role of the IκB-α/p53 Complex
نویسندگان
چکیده
TP53 is one of the most frequently-mutated and deleted tumor suppressors in cancer, with a dramatic correlation with dismal prognoses. In addition to genetic inactivation, the p53 protein can be functionally inactivated in cancer, through post-transductional modifications, changes in cellular compartmentalization, and interactions with other proteins. Here, we review the mechanisms of p53 functional inactivation, with a particular emphasis on the interaction between p53 and IκB-α, the NFKBIA gene product.

IκB-α: At the crossroad between oncogenic and tumor-suppressive signals
Nuclear factor κB (NF-κB) is an essential component of tumorigenesis and resistance to cancer treatments. NFKB inhibitor α (IκB-α) acts as a negative regulator of the classical NF-κB pathway through its ability to maintain the presence of NF-κB in the cytoplasm. However, IκB-α is also able to form a complex with tumor protein p53, promoting its inactivation. Recently, we demonstrated that IκB-α...
متن کاملFunctional and Physical Consequence of Human Immunodefficiency Virus Transactivator TAT Interaction with Human Cell Cycle Regulator p53
Human immunodeficiency virus (HIV) transactivator Tat is a potent activator of both viral and cellular genes. Tat has also been implicated in the development of AIDS-related malignancy. Here, we show that Tat physically and functionally is able to sequester the cell cycle check point protein p53. This sequestration results in non-functional promoter activity of cyclin-dependent kinase/cyclin i...

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...

Background: P53, p63, and p73 transcription factors which are belong to The p53 family, are conserved during evolution. They have important roles in many molecular and cellular functions, including tumor suppression, the development of epithelial cell layers, and the development of central nervous system and immune system. Studies show these molecules also have role in maintaining the genomic i...

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...
