Plumbagin Enhances the Anticancer Effects of PF Chemotherapy via Downregulation of the PI3K/AKT/mTOR/p70S6K Pathway in Human Tongue Squamous Cell Carcinoma
Figure 6
Combined PB and PF inhibited the PI3K/AKT/mTOR/p70S6K pathway in TSCC cells. (a) Representative blots demonstrating the expression of proteins involved in the PI3K/AKT/mTOR pathway in Cal27 and Cal27/CDDP cells following treatment with PB and/or PF. (b–e) A histogram demonstrating the expression level of PI3K, p-AKT/AKT, p-mTOR/mTOR, and p-p70S6K/p70S6K. Independent biological experiments were repeated three times. , , , and . PB, plumbagin; PF, cisplatin plus 5-fluorouracil; TSCC, tongue squamous cell carcinoma; and p-, phosphorylated.
