Aspirin enhances TRAIL-induced apoptosis via regulation of ERK1/2 activation in human cervical cancer cells.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) triggers tumor-specific apoptosis. However, some tumors and cancer cell lines are resistant to TRAIL. Here, the effect of the non-steroidal anti-inflammatory drug aspirin on sensitization of human cervical cancer cells to TRAIL and the underlying mechanism(s) of the effect were explored.
