Methylation Patterns of XAF1 Gene Promoter in Glioblastoma and Cervical Carcinoma Cells
Investigating the average methylation levels within the XAF1 gene promoter through CpG sites in various cell lines including SF295, SF539, HeLa, and SK-N-AS. Analysis of XAF1 transcript induction in response to IFN-β and 5-AZA-dC treatments.
