who incubated primary ovarian cancer cells with 5-aza-2′-deoxycytidine, a deoxy derivative of 5-Aza, which resulted in the hypomethylation of an STAT-1 binding site upstream of the promoter region and an exacerbated release of CXCL10 following IFN-γ stimulation (Peng et al., 2015). Here, CXCL10 is linked to ovarian cancer.
