Kang et al. reported that miR‐612 suppressed the malignant development of NSCLC by targeting BRD4 through the PI3K/Akt pathway.14 Feng and colleagues reported that miR‐34b exhibited a repressive effect on NSCLC cell proliferation and promotion effect on cell apoptosis. This evidence concerns the gene BRD4 and non-small cell lung carcinoma.
