It was reported that NEAT1 was able to interact with the G9a‐DNMT1‐Snail complex and suppressed the expression of E‐cadherin in osteosarcoma.33 These reports indicated that NEAT1 might regulate miR‐34a expression through DNA methylation besides direct binding,34 which needs future investigation to prove it. Here, EHMT2 is linked to osteosarcoma.
