Galangin induces apoptosis in gastric cancer cells via regulation of ubiquitin carboxy-terminal hydrolase isozyme L1 and glutathione S-transferase P

► Galangin inhibited proliferation of human gastric cancer SNU-484 cells. ► Galangin induced cell cycle arrest, activation of caspase, PARP, and MAP kinase. ► 2D electrophoresis approach was employed for comparative proteomic analysis. ► UCH L1 and glutathione S-transferase P were involved in galangin-induced apoptosis.
