PURPOSE The arginine to proline substitution at codon 72 represents a common aminoacidic polymorphism of the p53 protein. Recent data suggest that p53 codon 72 may modulate the response to cancer therapy. The aim of this study was to test the hypothesis that the p53 codon 72 genotype, evaluated in the tumor tissue and in the disease-free lymph node, is related to differences in disease-free and...

The present study analyzed the association of tumor protein p53 (TP53) Pro72Arg polymorphism with esophageal squamous cell carcinoma (ESCC) in the Mongolian population of Tongliao (Inner Mongolia, China). Restriction fragment length polymorphism-polymerase chain reaction was used to detect the genotype distribution of TP53 Pro72Arg polymorphism in 100 patients with ESCC and 50 healthy controls ...

Mutations in p53 are common events during carcinogenesis and have been suggested to affect sensitivity to chemotherapy. Recently, the common polymorphism at codon 72, resulting in either an arginine (72R) or proline (72P) residue, was shown to differentially affect the response to anticancer drugs. Here, we have generated isogenic lung cancer cell lines to evaluate the effect of six p53 hotspot...

Human papilloma virus (HPV) is considered to be responsible for a large part of vaginal and vulvar carcinomas, and the p53 codon 72 polymorphism has been implicated in susceptibility to cancer induced by this virus, but with contradicting results. In this study, we have investigated the prognostic value of the codon 72 polymorphism by real-time PCR (qPCR) in two cohorts of vaginal (n = 66) and ...

UNLABELLED p53 tumoral suppressor gene harbors a functional polymorphism which codes either arginine (Arg) or proline (Pro) in the protein p53 of codon 72. Such polymorphism has been associated with the development or prognosis of head and neck squamous cell carcinoma (HNSCC). AIM we assessed codon 72 p53 allelic frequencies and genotypes in HNSCC Iranian patients. STUDY DESIGN Case Study. ...

BACKGROUND Breast cancer is the most common cancer among women in Iran and the world. Multiple environmental factors and genetic variations such as genetic polymorphisms are of its main causes. p53 gene plays an important role in conserving and sustaining the genome as a tumor suppressing gene. Change and polymorphism at codon 72 of p53 gene are correlated with increased risk of lung, mouth, en...

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 A very high incidence of lung cancer is observed in Mizoram and Manipur, North East India. We conducted a population based case control study to establish associations of p53 codon 72 polymorphisms and interactions with environmental factors for this high incidence. MATERIAL AND METHODS A total of 272 lung cancer cases and 544 controls matched for age (±5 years), sex and ethnicity ...

BACKGROUND Although many epidemiologic studies investigated the TP53 codon 72 polymorphism and its association with cervical cancer (CC), definite conclusions cannot be drawn. AIM OF THE STUDY To evaluate the association between TP53 codon 72 polymorphism and risk of cervical cancer in the Chinese population. METHODS A computerized literature search was carried out in PubMed, Springer Link,...

BACKGROUND Previous studies on the association of p53 codon 72 (Arg72Pro) polymorphism with hematological malignancies risk have produced conflicting results. The purpose of this meta-analysis is to define the effect of p53 Arg72Pro polymorphism on hematological malignancies risk. METHODOLOGY/PRINCIPAL FINDINGS Through searching PubMed databases (or hand searching) up to April 2012 using the ...
