In this study, using the first described C57BL/6 (B6) TRAIL-sensitive experimental tumor models, we have characterized the innate and adaptive immune components involved in the primary rejection phase of an anti-mouse DR5 (mDR5) mAb, MD5-1 in established MC38 colon adenocarcinomas.
In this study, three different lung cancer cell lines and three different primary cell cultures established from patients with lung cancer (two patients with squamous cell lung carcinoma and one with adenocarcinoma) were screened for sensitivity to adenoviral delivery of TRAIL.
These results suggest that Adv-caspase-8 may be a good combination partner of TRAIL and enables TRAIL to be a more potent anticancer agent in a wide range of adenocarcinoma cells which demonstrate low expression of caspase-8.
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)/Apo2L has been recently identified as important in promoting programmed cell death in breast and colon adenocarcinomas.
