Infection of AGS cells with H. pylori for 1 h dramatically increased the expression of BIRC3 (gene of cIAP2), but not the expression of BIRC2 (gene of cIAP1), BIRC4 (gene of XIAP), BIRC5 (gene of Survivin) and other apoptosis related genes (Figs. 2a, b and S1). The gene discussed is XIAP; the disease is infection.
