To further elucidate the role of baicalein in the cisplatin sensitivity of resistant ovarian cancer cells, western blot analysis was carried out to measure the protein expression levels of PI3K-p85α, P-Akt, Akt, P-mTOR, mTOR, P-Erk, Erk, P-p38, p38 and Bcl-2 (Fig. 6A-C). Here, MTOR is linked to ovarian carcinoma.
