Association between Gene Promoter Methylation and Cervical Cancer Development: Global Distribution and A Meta-analysis.

DNA methylation is the main epigenetic event for gene silencing and is associated with carcinogenesis. In this meta-analysis, we evaluated the association between the methylation of the promoter regions of , and genes and the risk of cervical cancer development and progression. Overall, 194 eligible studies were identified assessing the associations of promoter methylation status of aforementioned genes with low- and high-grade squamous intraepithelial lesions (LSIL and HSIL) and cervical cancer development.
