Abstract

Opposing pro- and anti-apoptotic actions of TRAIL and the inhibitors of apoptosis (IAPs) contribute to the cell's decision to survive or die. We demonstrate that in H157 human lung carcinoma cells, etoposide and doxorubicin induce the NF-κB-dependent expression of both pro- and anti-apoptotic proteins including TRAIL and its death receptor, DR5, and IAPs. Inhibition of NF-κB activation in H157 cells in response to genotoxin resulted in loss of cell surface expression of TRAIL and DR5, aggressive growth and chemotherapy resistance of tumors in nude mice. Similar to the paracrine TRAIL response in H157 cells, the sensitivity of normal lung and breast epithelium and carcinomas to undergo genotoxin-induced apoptosis correlates strongly with cell surface expression of TRAIL. Suppression of TRAIL signaling by expression of the TRAIL decoy receptor, DcR1, confers chemo-resistance to cancer cells. These findings demonstrate that TRAIL signaling via its death receptors is a significant contributor to genotoxin-induced apoptosis in human epithelial carcinomas.
