Figure 6. PTBP1 is directly targeted by miR-1205. (A, B) Molecular interactions between miR-1205 and PTBP1. (C, D) Relative PTBP1 expression in OS tissues and cell lines. (E) MiR-1205 overexpression reduces PTBP1 expression in OS cells. (F, G) Suppressing PTBP1 reduces HOS cells proliferation and invasion. *P < 0.05.
