Wogonin also induced nasopharyngeal carcinoma (NPC) cell apoptosis via inhibiting the activity of glycogen synthase kinase 3β (GSK-3β), a multifunctional serine/threonine kinase that was reported to inhibit apoptosis, and down-regulating the expression of ΔNp63, a survival factor in NPC cells [7]. This evidence concerns the gene GSK3B and nasopharyngeal carcinoma.
