PURPOSE Recent studies have highlighted that the p53 codon 72 polymorphism plays a crucial role in modulating wild-type p53 apoptotic capacity, and as such may influence the response to chemotherapy. Thus, the purpose of this study was to investigate whether the p53 codon 72 polymorphism might influence pathologic response to neoadjuvant chemotherapy in primary breast cancer. EXPERIMENTAL DES...

Endometriosis is a benign gynaecologic disease that is associated with a certain risk for malignant degeneration. The disease has a genetic background, but the locations of possible genomic aberrations are still poorly clarified. In this context, the proline form of TP53 codon 72 polymorphism has been recently associated with the risk of developing endometriosis. In this case-control study, we ...

Primary open angle glaucoma (POAG) is the most common type of glaucoma. The p53 codon 72 Arg-Pro (CGC to CCC) polymorphism of exon 4 affects various biological properties; recently, it was reported that this polymorphism affects the ability to induce apoptosis in vitro. Various genotypes have been found to be significantly associated with POAG. We examined the distribution of this polymorphism ...

The aim of this report is to review and evaluate, in a comprehensive manner, the published data regarding the contribution of genetic polymorphisms to risk of head and neck cancer (HNC). All relevant studies available in MEDLINE and published before July 2007 were identified. Studies carried out in humans that compared HNC patients with at least 1 standard control group were considered for anal...

AIM Allelic polymorphism in codon 72 of the p53 tumor suppressor gene causes imbalance of p53 protein expression. Earlier studies have shown association between allelic polymorphism in codon 72 of the p53 gene with risk of ovary cancer (OC); however the results are inconclusive and conflicting. Therefore, we performed this meta-analysis to investigate the relation between p53 codon 72 Arg>Pro p...

The polymorphic variants at codon 72 of the p53 gene were shown to be functionally distinct in vitro, whereby the arginine (arg) variant induces apoptosis more efficiently than the proline (pro) variant. From the evidence that the DNA mismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the age of onset of disease in HN...

BACKGROUND Infections with high-risk human papillomaviruses (HPVs), causatively linked to cervical cancer, might also play a role in the development of prostate cancer. Furthermore, the polymorphism at codon 72 (encoding either arginine or proline) of the p53 tumor-suppressor gene is discussed as a possible determinant for cancer risk. The HPV E6 oncoprotein induces degradation of the p53 prote...

PURPOSE A common polymorphism of the tumor suppressor gene TP53 at codon 72 has been associated with human cancer susceptibility. The prognostic role of the polymorphism was assessed in 102 patients with advanced gastric adenocarcinoma. EXPERIMENTAL DESIGN We followed up 102 consecutive Caucasian patients with advanced gastric adenocarcinoma for >5 years and determined the status of the TP53 ...

The p53 gene is one of the most extensively studied human genes because of its role as a tumor suppressor. A common polymorphism of the p53 gene at codon 72 has been associated with human cancer susceptibility and prognosis. Human papilloma virus (HPV) has also been suggested to be involved in the pathogenesis of esophageal cancers. In this study, we investigated codon 72 polymorphism in 40 eso...
