Baicalein inhibits cyclin D1 overexpression and arrests the cell cycle at G0/G1 phase through Wnt/β-catenin and protein kinase B/glycogen synthase kinase-3β (AKT/GSK-3β) signaling pathways to suppress proliferation and induce apoptosis of human cervical cancer HeLa and SiHa cells [20,21]. The gene discussed is CCND1; the disease is cervical carcinoma.
