- Cyclin A1 promoter hypermethylation in human papillomavirus-associated cervical cancer

This study demonstrates the strong association between CCNA1 promoter hypermethylation and invasive HPV-associated CC indicates that this gene could serve as an effective molecular marker. Moreover, our finding, in comparison with previous reports, [13,14] also suggests that there is a possible molecular link between oncogenic HPVs, TP53 and CCNA1 promoter hypermethylation.


CC: cervical cancer, CCNA1: cyclin A1, SILs: squamous intraepithelial lesions, HPV: Human papillomavirus, WBC: white blood cell
