Figure 3. The expression of PI3KCA (A), PI3KR1 (B) and PTEN (C) was measured using qPCR in the control group, PMO group, PMO+Exos group and exosome group. (D) The expression of p-AKT (Thr308), p-AKT (Ser 473) and total-AKT were detected using western blotting in the control group, PMO group, PMO+Exos group and exosome group. The results of p-AKT (Thr308) (E), p-AKT (Ser 473) (F) were calculated using Image J software.
