Our recent work showed that low-dose DNMT inhibitor (DNMTi) treatment sensitizes colon cancer cells to EZH2 inhibitors (EZH2i), synergistically upregulating tumor suppressor genes (TSGs) and transposable elements through activation of the calcium-calcineurin-NFAT signaling pathway. This evidence concerns the gene DNMT1 and malignant colon neoplasm.
