Figure 5. In vitro experiments demonstrated that the overexpression of miR-506-3p could enhance autophagy by regulating the PI3K signaling pathway. (A) Protein bands of PIK3CA, p-PI3K, t-PI3K, p-mTOR, t-mTOR, Beclin, LC-3II and ATG5. (B) Relative protein expressions of PIK3CA, p-PI3K, t-PI3K, p-mTOR, t-mTOR, Beclin, LC-3II and ATG5. **P < 0.01, nsP > 0.05.
