1 c-Met-Akt pathway-mediated enhancement of inhibitory c-Raf phosphorylation is involved in vitamin K1 and sorafenib synergy on HCC growth inhibition. Sorafenib MET proto-oncogene, receptor tyrosine kinase Homo sapiens
2 However, vitamin K1 enhanced sorafenib-induced c-Met phosphorylation at Tyr-1349, a DEP-1 protein phosphatase acting site, and consequently induced phosphorylation of PI3K-Akt. Sorafenib MET proto-oncogene, receptor tyrosine kinase Homo sapiens
3 Both PI3K inhibitor Ly294002 as well as dominate negative Akt plasmid transfection antagonized vitamin K1 plus sorafenib actions on c-Raf phosphorylation and cell growth inhibition, suggesting that c-Met-PI3K-Akt signaling pathway mediated inhibitory c-Raf phosphorylation may play a central role in vitamin K1 plus sorafenib synergy in inhibiting HCC cell growth. Sorafenib MET proto-oncogene, receptor tyrosine kinase Homo sapiens
4 Both PI3K inhibitor Ly294002 as well as dominate negative Akt plasmid transfection antagonized vitamin K1 plus sorafenib actions on c-Raf phosphorylation and cell growth inhibition, suggesting that c-Met-PI3K-Akt signaling pathway mediated inhibitory c-Raf phosphorylation may play a central role in vitamin K1 plus sorafenib synergy in inhibiting HCC cell growth.
