MKI67 and neoplasm: Intratumoral injections of miR-24 and miR-27b or miR-125a-5p, without any drug treatment, significantly reduced tumor growth as assessed also by a decrease in proliferation (Ki67) and tumor weight (p < 0.05, Fig. 6e and f; Supplementary Fig. S7C), suggesting that these microRNAs may have therapeutic potential in NSCLC.
