A few genetic polymorphisms of TP53 are known to have a significant effect on cancer susceptibility. Intron 3 16 bp duplication polymorphism of TP53 has been reported to be associated with breast cancer, colorectal cancer, lung cancer and other cancers, but the reported results remain inconclusive. The present study, a meta-analysis including a total of 9801 cases and 10,391 controls from 26 st...

BACKGROUND Endometriosis is a female health disorder that occurs when cells from the lining of the uterus grow in other areas of the body. The cause of endometriosis is unknown. OBJECTIVE The purpose of this study was to investigate TP53 gene codon 72 polymorphism in women with endometriosis and compared it with healthy samples in Isfahan. MATERIALS AND METHODS We undertook a case-control s...

Tumor protein p53 (TP53) is the best-known tumor suppressor gene and plays a crucial role in carcinogenesis. The TP53 Arg 72 Pro polymorphism has been reported to be a risk factor for several types of cancer, but its association with pancreatic cancer has not been fully evaluated. Therefore, we investigated the effects of this polymorphism on pancreatic cancer in relation to smoking and drinkin...

Benzene is a recognized hematotoxicant and carcinogen that produces genotoxic damage. DNA double-strand breaks (DSB) are one of the most severe DNA lesions caused directly and indirectly by benzene metabolites. DSB may lead to chromosome aberrations, apoptosis and hematopoietic progenitor cell suppression. We hypothesized that genetic polymorphisms in genes involved in DNA DSB repair may modify...

PURPOSE We made a preliminary attempt to study mutations in exons 5-8 (the DNA binding domain) of the tumor suppressor gene TP53, in urinary bladder cancer patients from Kashmir. Further the relation of clinicopathological characteristics with mutation status was asessed. MATERIALS AND METHODS The study population consisted of 60 patients diagnosed with transitional cell carcinomas who underw...

INTRODUCTION The aim of this study was to detect TP53 Arg72Pro polymorphism in postmenopausal patients with endometrial cancer (EC), to evaluate the risk of EC connected with it, as well to check for possible relationships with staging, grading and some risk factors of this neoplasm. MATERIAL AND METHODS Endometrial samples from 152 women with EC and from 50 cancer-free ones were taken for ge...

Tobacco smoking is a strong cause of lung cancer. However, because only a small proportion of smokers develop the disease, other factors, including genetic susceptibility, may be important in determining lung cancer risk. Polymorphisms in the TP53 tumor suppressor gene and HRAS1 proto-oncogene have been associated in some studies with this cancer; we sought to replicate these associations in an...

Differences in the pathogenesis of microsatellite stable (MSS) sporadic colorectal cancers (CRCs) between left-sided CRC (LC) and right-sided CRC (RC) have not been clarified. To identify pathogenesis-related genomic differences between MSS CRCs within the two locations, we performed a comprehensive molecular analysis using crypt isolation with samples from 92 sporadic CRCs. Microsatellite inst...

PURPOSE Although p53 is one of the most studied genes/proteins in ovarian carcinomas, the predictive value of p53 alterations is still ambiguous. EXPERIMENTAL DESIGN We performed analyses of the TP53 mutational status and its protein expression using immunohistochemistry. Moreover, the single nucleotide polymorphism SNP309 in the P2 promoter of the MDM2 gene was investigated. We correlated th...

The purpose of this study was to evaluate the association between ATM, TP53 and MDM2 polymorphisms in prostate cancer patients and morbidity after radiotherapy. The presence of ATM (rs1801516), TP53 (rs1042522, rs1800371, rs17878362, rs17883323, and rs35117667), and MDM2 (rs2279744) polymorphisms was assessed by direct sequencing of PCR fragments from 48 patients with histologically proven pros...
