NEAT1 and colorectal carcinoma: We also found that NEAT1 knockdown or miR‐34a overexpression remarkably suppressed the growth and enhanced the sensitivity to 5‐FU of CRC cell lines; further investigation disclosed that NEAT1 facilitated autophagy in CRC cell lines via downregulating miR‐34a and thus depressing miR‐34a putative targets which were involved in autophagy.
