The proposed signaling pathway activated by CTS in CCA cells.
Notes: The potential mechanism of apoptosis induced by CTS in HCCC-9810 and RBE cells. Sustained suppression of JAK2/STAT3 and PI3K/Akt/NFκB signaling pathways by CTS results in deregulation of downstream gene (Bcl-2 family, Caspases family) expression and should contribute to apoptosis progression in CCA cells. *According to Yu and Jove31 and Rane and Reddy,32 JAKs play an essential role in mediating the activation of both STAT and PI3K/Akt signaling.
Abbreviations: CTS, cryptotanshinone; CCA, cholangiocarcinoma; PARP, poly (ADP-ribose) polymerase.
