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). Here, MALAT1 is linked to urinary bladder carcinoma.
