Lexatumumab, a human agonistic monoclonal antibody against tumor necrosis factor (TNF)-related apoptosis-inducing ligand receptor-2 (TRAIL-R2), is a promising molecular-targeted therapeutic agent. Our past study indicated that low concentrations of doxorubicin sensitized renal cell carcinoma (RCC) cells to lexatumumab-mediated apoptosis. The present study was designed to examine the cellular and molecular effects of lexatumumab and anthracyclines in RCC cells.
