Background: The most frequently mutated tumor suppressor gene found in human cancer is p53. In a normal situation, p53 is activated upon the induction of DNA damage to either arrest the cell cycle or to induce apoptosis. However, when mutated, p53 is no longer able to properly accomplish these functions. The aim of this study was to investigate the expression of p53 gene in cases of skin cancer...

the p53 protein is expressed in all normal cells and appears to function in cell cycle regulation. abnormally higli levels of the protein are found in many different types of cancer. in breast cancer, overexpression of p53 is associated with point mutations within highly conserved regions of the p53 gene. these altered genes encode stable p53 protein that can be detected by standard immunohisto...

Background: Prostate cancer is one of the most commonly diagnosed cancers in males. Tumor suppressor gene p53 plays an important role in causing cell cycle arrest and allowing apoptosis to proceed. Objective: To investigate the expression of p53 protein and its relation to apoptosis and prostate cancer traditional prognostic indicators. Methods: In this study expression of p53 was examined in p...

Abstract P53 is frequently mutated in most human cancers, including glioblastoma (GBM). Many p53 mutants acquire gain-of-function oncogenic effects through only partially understood mechanisms. To investigate the role of mutant (MUT-p53) GBM, we performed ChIP-seq wildtype (WT-p53) and MUT-p53 GBM cell lines. Among 2834 unique peaks reads cells, found 242 long non-coding RNAs (lncRNAs) with up ...

Recent studies have shown that FMS-like receptor tyrosine kinase 3 (Flt3) has a beneficial effect on cardiac maladaptive remodeling. However, the role and mechanism of Flt3 in mitochondrial dynamic imbalance under stress remains poorly understood. This study aims to investigate how regulates p53-mediated optic atrophy 1 (OPA1) processing fragmentation improve Mitochondrial cardiomyocytes was in...

Abstract A poptosis r elated protein in T GF-? s ignaling pathway (ARTS) was originally discovered cells undergoing apoptosis response to TGF-?, but ARTS also acts downstream of many other apoptotic stimuli. induces by antagonizing the anti-apoptotic proteins XIAP and Bcl-2. Here we identified pro-apoptotic Sept4/ARTS gene as a p53-responsive target gene. Ectopic p53 variety p53-inducing agents...

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...
