In addition, a combined treatment with curcumin (>50 μM) and wikstroflavone B (WFB) (>100 μM) inhibited viability, migration, colony formation and invasion in four human nasopharyngeal carcinoma (NPC) cell lines, by modulating several proteins, such as survivin, cyclin D1, p53 and p21, STAT3 and FAK [203]. Here, PTK2 is linked to nasopharyngeal carcinoma.
