Glabridin promotes tumor cell apoptosis by upregulating BAX, Caspase-3, Caspase-8, and Caspase-9 and downregulating Bcl-2, and inhibits cancer cell invasion and metastasis by downregulating N-Cadherin and upregulating E-Cadherin to reduce cell adhesion. The gene discussed is CDH2; the disease is cancer.
