the tp53 tumor suppressor gene plays important roles in genomic stability. a common polymorphism at codon 72 of tp53 gene has been associated with increased risk for many human cancers. the p53 protein is expressed in colorectal cancer, but the reported prevalence of its expression varies widely. in the present study, the p53 protein expression in different genotypes of its codon 72 , was inves...
We examined whether p53 codon 72 polymorphism confers prostate cancer risk by conducting a meta-analysis. Two investigators independently searched the Pubmed, Embase and CBM databases. This meta-analysis was made of seven case-control studies, that included 892 prostate cancer cases and 1020 healthy controls. Meta-analysis results based on all the studies showed no significant association ...
Objective: The polymorphic variants at codon 72 of the p53 gene, encoding proline or arginine at residue 72, produce marked changes in the p53 structure. From the evidence that the DNA mismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that codon 72 variations may influence the prevalence of microsatellite instability (MSI), a feature of malignancies associat...
BACKGROUND Deletion or functional loss of the p53 tumor suppression gene plays a role in oncogenic transformation. The codon 72 polymorphism on exon 4 in the p53 gene produces variant proteins with either arginine (Arg) or proline (Pro), and is associated with an increased susceptibility of cancers of the lung, esophagus, breast, cervix and nasopharynx on a genetic basis. We designed this study...
The objective of this study was to identify whether polymorphic variants of p53 at codon 72 and p21 at codon 31 were associated with increased risk for cervical cancer, either independently or jointly, among Chinese women from southern Han. We genotyped p53 codon 72 and p21 codon 31 polymorphisms of peripheral blood DNA from 104 cervical cancer patients and 160 controls. Genotyping was confirme...
