Detection of the effect of RAPA on p-Akt and p-mTOR expressions in PEBP4-treated cells using Western blotting. (A) Expressions of Akt, p-Akt, mTOR, and p-mTOR in cells in each group; (B) p-Akt/Akt in each group; (C) p-mTOR/mTOR in each group. *P<0.05 versus normal control group. RAPA, rapamycin; PEBP4, phosphatidylethanolamine-binding protein 4; p-mTOR, phosphorylated mTOR.
