The bases can be purines or pyrimidines. Examples of purine bases include adenine A and guanine G.

TP53 tumor protein p53 [ human ] Gene ID: The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome.

Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms.

Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants PMIDs: The overexpression of miR significantly increased p53 at the protein level, thereby inducing apoptosis.

Apoptosis pathways are impaired in fibroblasts from patients with SSc, leading to chronic fibrosis. Low TP53 expression is associated with drug resistance in colorectal cancer. The activation of p38 in response to low doses of ultraviolet radiation was postulated to be protective for pinactive cells.

TP53 missense mutations are associated with castration-resistant prostate cancer. P53 degradation is mediated by COP1 in the breast cancer. A direct link between Y14 and p53 expression and suggests a function for Y14 in DNA damage signaling.

TP53 Mutation is associated with Mouth Neoplasms. Consistently, forced expression of p53 significantly stimulated ACER2 transcription. Notably, pmediated autophagy and apoptosis were markedly enhanced by ACER2. Arg72Pro polymorphism may be considered as a genetic marker for predisposition to breast cancer in Moroccan population Kidney biopsies from patients with IgA nephropathy and diabetic nephropathy exhibited substantial activation of p53 and STAT3, decreased expression of SOCS7, and increase in profibrotic proteins and miRa-3p.

Low TP53 expression is associated with hepatocellular carcinoma. TP53 mutations are associated with colorectal liver metastases. High expression of TP53 is associated with oral epithelial dysplasia and oral squamous cell carcinoma.

Low TP53 expression is associated with chemoresistance in ovarian cancer. Differentiation-dependent downregulation of p53 is a prerequisite for activating autophagy in the syncytiotrophoblast.

Deletion of NF1 leads to mutant oligodendrocyte precursor cell OPC expansion through increased proliferation and decreased differentiation, the deletion of p53 impairs OPC senescence. Study discovered that a pdependent tumor-suppressor TS network triggered by nucleolar stress is tuned by miR Activation of this network, the pmiR circuit, enables induction of apoptosis in p53 WT cancer cells by G2 phase-specific positive-feedback regulation of p53 mediated by direct repression of EG5.

In silico molecular docking and dynamics studies with MDM2-p53 protein revealed that HTMF was more potent compound that could inhibit the binding of MDM2 with p53 and, therefore, could trigger apoptosis in cancer cell.

Expression of Ki was lower and expression of p53 was higher in primary tumors than in ascitic cells This review outlines the roles of important E3 Ub -ligases and their splice variants in maintaining cellular p53 protein homeostasis.

The results of the present study additionally suggest that the propranololinduced HemEC apoptosis pathway is a mitochondrial apoptosis pathway and is regulated by p53BAX signaling.


Our findings suggested that RBM38 may be a core contributor in stabilizing the pmdm2 loop function to prevent hepatocellular carcinoma HCC and a potential novel target to provide a therapeutic strategy for HCC by inhibiting mdm2 and rescuing p53 from inactivation.Health Insurance Consumer Guide Health Insurance Association of America HSA Insider - Health Savings Account finder - free insurance quotes Kaiser Family Foundation Long-Term Care Financial Partners The Jewish Floridian has absorbed the Jewish Unity and the Jewish Weekly.
