Esophageal Carcinogenesis
Esophageal cancer is the sixth leading cause of cancer death and remains one of the least survivable cancers. Esophageal cancers show wide variations in incidence in different population, suggesting that environmental or lifestyle risk factors could be controlled to reduce risk of these diseases. There are two major histopathologic types (squamous cell carcinoma and adenocarcinoma) of esophagea...
متن کاملRole of MLH1 methylation in esophageal cancer carcinogenesis and its clinical significance
The mutL homolog-1 (MLH1) is a DNA mismatch repair gene and has been reported to be frequently methylated in numerous cancers. However, the association between MLH1 methylation and esophageal cancer (EC), as well as its clinical significance, remains unclear. Hence, we conducted a systematic meta-analysis based on 19 articles (including 1384 ECs, 345 premalignant lesions, and 1244 healthy contr...
متن کاملAberrant methylation during cervical carcinogenesis.
We studied the pattern of aberrant methylation during the multistage pathogenesis of cervical cancers. We analyzed a total of 73 patient samples and 10 cervical cancer cell lines. In addition, tissue samples [peripheral blood lymphocytes (n = 10) and buccal epithelial cells (n = 12)] were obtained from 22 healthy volunteers. On the basis of the results of preliminary analysis, the cervical samp...
متن کاملAberrant DNA methylation in cervical Carcinogenesis
Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however, additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer. DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis. In this review, we summarize DNA methylation within the HPV genome and ...
متن کاملAnalysis of SEPT9 Gene Promoter Methylation Status in Esophageal Squamous Cell Carcinoma
Introduction: The changes in the level of SEPT9 gene promoter methylation can contribute to the formation of esophageal squamous cell carcinoma. The aim of this study was to evaluate the level of changes in the level of SEPT9 gene promoter methylation in the esophageal squamous cell carcinoma. Methods: In the present case-control study, we collected 75 paraffin blocks of esophageal cancer tiss...
