RBM47 and colorectal carcinoma: Treatment of SW480 and SW620 CRC cells with the DNA methyltransferase inhibitor 5-aza-2’-deoxycytidine and the histone deacetylase inhibitor trichostatin A (TSA) resulted in a significant re-activation of RBM47 mRNA expression, further confirming that CpG methylation is responsible for the repression of RBM47 expression (Fig. 7d).
