Abstract
To investigate the methylation pattern in promoter region of RASSF1A and PTEN genes in epithelial ovarian cancer patients in North India.Fifty patients and 20 healthy controls were studied. Isolation of genomic DNA from peripheral blood and methylation-specific polymerase chain reaction (MSP) were applied for analysis.17 of 50 patients (34.0%) were found to be methylated for RASSF1A gene, whereas methylation of the PTEN gene occurred in 8 of 50 cases (16.0%). A statistically significant result was obtained (P = .01) for RASSF1A gene and correlated with the patients' clinicopathologic features.Hypermethylation of both RASSF1A and PTEN genes in blood DNA from ovarian cancer patients might offer an exposition for early diagnosis of the malignancy.
