TP53, a tumor suppressor gene, plays a critical role in cell cycle control, apoptosis, and DNA damage repair. Previous studies have indicated that the TP53 gene Arg72Pro (rs1042522 C>G) polymorphism is associated with susceptibility to various types of cancer. We evaluated the association of the TP53 gene rs1042522 C>G polymorphism with neuroblastoma susceptibility in a hospital-based study amo...
Non-small cell lung cancer (NSCLC) is the most common form of lung cancer. Genetic polymorphisms in tumour suppressor genes and genes encoding xenobiotic metabolising enzymes alter the activity of their corresponding enzymes and are important individual susceptibility factors for NSCLC. Because of the lack of information in literature, the aim of our study was to investigate the role of the tum...
Breast cancer (BC) is a complex disease influenced by environmental and genetic factors. The disease has important genetic and environmental components, most of them are still unknown. An important role of gene polymorphisms related to the risk of developing BC has been reported. However, the results have been controversial. We investigated the association of TSER, MTHFR C677T, p53 codon 72 and...
The MDM2 protein plays an important role in the regulation of cell proliferation and apoptosis via ubiquitination and proteasome-mediated degradation of p53. The genetic polymorphism rs2279744 (c.309T>G) of the MDM2 gene is reportedly associated with susceptibility and/or prognosis in various cancers. In this study, we investigated the risk factors for worse survival in patients with lung adeno...
The allele frequencies of two functional single-nucleotide polymorphisms (SNPs) in the p53 pathway, the MDM2 SNP309 and TP53 Arg72Pro, vary dramatically among populations. That the frequencies of the TP53 SNP follow a clinal distribution may suggest that selective pressure from environmental variables correlated with latitude contributed to these observed population differences. Recently, winte...
مقدمه: شکست مکرر در لانه‌گزینی (RIF)، شایع ترین علت عدم موفقیت بارداری بعد از لقاح آزمایشگاهی است. از میان علل مختلف RIF، نقش عوامل ژنتیکی مادر به عنوان یکی از مهم‌ترین عوامل است. یکی از پلی‌مورفیسم های مطرح در این زمینه، پلی‌مورفیسم کدون 72 ژن P53 می‌باشد. با توجه به مدارک موجود در مورد ارتباط این پلی مورفیسم با افزایش خطر وقوع RIF در جمعیت های مختلف در صورت اثبات این ارتباط در جمعیت ایرانی می...
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...
Ionizing radiation, such as that emitted by uranium, may cause mutations and consequently lead to neoplasia in human cells. The TP53 gene acts to maintain genomic integrity and constitutes an important biomarker of susceptibility. The present study investigated the main alterations observed in exons 4, 5, 6, 7, and 8 of the TP53 gene and adjacent introns in Amazonian populations exposed to radi...
