From: Regulation of microRNAs by epigenetics and their interplay involved in cancer
The role of miRNAs in mediating the crosstalk between epigenetic regulators. DNMT1 contributes to miR-1 silencing in HCC cells, thereby promoting the accumulation of its target HDAC4. The miR-29, which targets DNMT3, is down-regulated by HDACs in AML. Likewise, miR-26a and miR-137 are silenced by promoter CpG island hypermethylation, which induces the up-regulation of the target gene LSD1 in colorectal adenomas and EZH2 in prostate cancer.
