miR-877 inhibits NSCLC cell growth by targeting ACP5 and inactivating the PI3K/AKT pathway. The experiment was performed three times independently. The results are presented as the mean ± standard deviation. Compared to the miR-NC group, * p < 0.05, ** p < 0.01; compared to the miR-877 group, # p < 0.05. miR-877, microRNA-877; LC, lung cancer; ACP5, tartrate resistant acid phosphatase 5; PI3K, phosphatidylinositol-3 kinase; AKT, protein kinase B; NC, negative control
