Cervical cancer is the third most common cancer in women worldwide and occurs frequently in women under 25 years of age . Of the causes of cervical cancer, an infection of high risk human papillomavirus (HPV16 and HPV18) is most prevalent associated through sexual transmission. Not only HPV infection but also in molecular level is seen in carcinogenesis. Here, methylation status of HCP5, HPC5, and TNFRSF8 was studied by methylation specific primer PCR (MSP-PCR) and RT-PCR was studied for the expression of these genes .For correlation and expression study, HeLa cervical cancer cell line was used as model, after treated with 5’ Azacystidine, methylation and expression status were detected. The result showed that only TNFRSF8 could be studied for methylation status in cervical cancer and normal cervix cells. From 45 cervical cancer cells and 36 normal cervix cells, methylation status in cervical were found 68.88% whereas both methylation and unmethylation could be detected in normal cervix 44.44 %. For correlation between methylation and expression, the result show that methylation decreased when treated HeLa cell with 5’Azacytidine, but the experiment in expression part was failed, therefore we could not interpret the result. HCP5 was detected methylation in both HeLa and white blood cell, therefore this gene was excluded in this experiment. HPC5 could not find the sequence from all databases. Taken together, TNFRSF8 may play role in tumor suppressor gene in cervical cancer whereas HCP5 does not. And for HPC5 ,it’s a novel gene that need to study more to confirmed that it’ actually exist.
