Treated hepatocellular carcinoma with an IC50 of GL extract (47.5 ug/ml) upregulates pro-apoptotic BAX and downregulates anti-apoptotic BCL2, which disrupts the BAX/BCL2 ratio, leading to activation of caspase 3 inside treated HepG2 cells. The gene discussed is BAX; the disease is hepatocellular carcinoma.
