background : colorectal cancer is the second cause of mortality in developed countries. the p53gene and some of it's polymorphisms are among the causes for cancer development.the purpose of this study is to evaluate the relationship between the p53 codon 72 polymorphism in colorectal adenocarcinoma specimens compared with controls. materials and methods : we performed a case-control study among...

background : gastric cancer as the fourth most frequent malignancy worldwide was known to have the highest rate among cancer-related disorders in ardabil province. the product of tp53 gene regulated  the cell cycle process and acts as a tumor suppressor factor. the polymorphism p53 arg72pro (rs1042522) has been reported to be associated with many type of cancers.  the purpose of the present stu...

Backgrounds and Aims: P53 gene is regarded important in pathogenesis of different cancers. Therefore, this study aimed to investigate the frequency of p53 gene codon 72 Arg/Pro polymorphism in women suffering from breast cancer. Materials and Methods: A total of 90 patients with breast cancer and 83 matched healthy control women participated in this case-control study. Genomic DNA was extrac...

Background: Glaucomatous neuropathy is a type of cell death due to apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (POAG) has been studied in some ethnic groups. This study is the first association analysis of POAG and p53 codon 72 polymorphism in Iranian patients...

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 ...

A polymorphism at codon 72 of gene p53 results in the presence of either arginine or proline at this position. We investigated the distribution of p53 codon 72 polymorphism in cervical cancer patients and a control group of healthy women from Poland. Our results do not confirm the hypothesis that the p53 codon polymorphism could play a role as a factor for squamous carcinoma of the cervix.

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...

In addition to a common polymorphism at codon 72, the p53 tumor suppressor gene also contains a rare single nucleotide polymorphism at amino acid 47. Wild type p53 encodes proline at this residue, but in <5% of African Americans, this amino acid is serine. Notably, phosphorylation of the adjacent serine 46 by the proline-directed kinase p38 MAPK is known to greatly enhance the ability of p53 to...

abstract   background: the polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. from the evidence that the dnamismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability a feature of malig...
