According to a recent publication by Peng et al., epigenetic alterations of cancer cells by inhibition of EZH2 and DNA methyltransferase 1 (DNMT1) in a mouse model of ovarian cancer resulted in increased expression of the Th1-type chemokines CXCL9 and CXCL10 in cancer cells leading to increased trafficking of effector T cells to the tumor site and decreased tumor volume (36). The gene discussed is CXCL9; the disease is neoplasm.
