MALAT1 and urinary bladder cancer: We further established the miR‐384 inhibition or mimic in bladder cancer cells, and we found that miR‐384 inhibitor substantially (p < 0.001) elevated the transcriptional expression level of MALAT1, by 3.7‐fold and 2.8‐fold, in 5637 and 253J cells, respectively, whereas miR‐384 mimics had the opposite effect (Figure 4B).
