Dexamethasone and Tumor Necrosis Factor-α Act Together to Induce the Cellular Inhibitor of Apoptosis-2 Gene and Prevent Apoptosis in a Variety of Cell Types

Abstract excerpt

Using microarray technology, we analyzed 12,000 genes for regulation by TNF-alpha and the synthetic glucocorticoid, dexamethasone, in the human lung epithelial cell line, A549. Only one gene was induced by both agents, the cellular inhibitor of apoptosis 2 (c-IAP2), which was induced 17-fold and 5-fold by TNF-alpha at 2 h and 24 h, respectively, and increased 14-fold and 9-fold by dexamethasone at 2 h and 24 h,...
