TP53 codon 72 polymorphism affects accumulation of mtDNA damage in human cells

Human TP53 gene is characterised by a polymorphism at codon 72 leading to an Arginine-to-Proline (R/P) substitution. The two resulting p53 isoforms have a different subcellular localisation after stress (more nuclear or more mitochondrial for the P or R isoform, respectively). p53P72 variant is more efficient than p53R72 in inducing the expression of genes involved in nuclear DNA repair. Since ...

The Role of TP53 Gene Codon 72 Polymorphism in Leukemia

The purpose of this meta-analysis was aimed to evaluate the association of tumor protein p53 (TP53) gene codon 72 polymorphism with leukemia susceptibility. We searched PubMed to identify relevant studies, and 16 case-control studies from 14 published articles were identified as eligible studies, including 2062 leukemia patients and 5826 controls. After extracting data, odds ratio (OR) with the...

Analysis of TP53 Codon 72 Polymorphism in Mucinous and Non-Mucinous Colorectal Adenocarcinoma in Isfahan, Iran

Background: The tumor suppressor gene TP53 (alias p53) located on chromosome 17 is involved in various cancers. Case-control studies have shown that p53 codon 72 polymorphism modulates the prognosis and susceptibility to various malignancies. We undertook the present study to explore a possible association between mucinous and non-mucinous adenocarcinomas with different genotypes or alleles at ...

TP53 codon 72 single nucleotide polymorphism in chronic lymphocytic leukemia.

UNLABELLED Defects in the tumor suppressor gene TP53 are known to be important in chronic lymphocytic leukemia (CLL) and TP53 inactivation is associated with a particularly aggressive form of the disease. The single nucleotide polymorphism in the TP53 gene at codon 72 (rs1042522), results in amino acid substitution influencing apoptotic potential of TP53 protein. The aim of the study was to eva...

TP53 codon 72 polymorphism in adult soft tissue sarcomas.

Soft tissue sarcomas (STS) are tumors of mesodermal origin, comprising about 1% of all adult neoplasms. Management of such tumors is an important medical challenge. TP53 codon 72 polymorphism results in either the arginine or proline form of the p53 protein; several studies have investigated whether codon 72 polymorphisms are risk and prognostic factors for cancer. We investigated p53 codon 72 ...
