miR-26b expression is inversely correlated with RAB31 expression in OS tissues. (A) miR-26b levels are significantly lower in osteosarcoma tissues compared with adjacent non-tumor tissues. **P<0.01 vs. adjacent. (B) A significant inverse correlation was identified between miR-26b and RAB31 expression levels in osteosarcoma tissues. (C) miR-26b levels were significantly lower in osteosarcoma cell lines compared with the osteoblastic cell line hFOB 1.19. **P<0.01 vs. hFOB 1.19. Data are presented as the mean ± standard deviation. miR, microRNA; RAB31, Ras-related protein Rab-31.
