a, Expression of TNF-related apoptosis-inducing ligand (TRAIL-R1) (56 kDa) and TRAIL-R2 (48 kDa) in human colonic adenocarcinoma cell lines. Cellular lysates were separated by SDS-PAGE and transferred to nitrocellulose. TRAIL-R1 and TRAIL-R2 levels were detected by Western blotting. b, Detection of TRAIL-R3 and TRAIL-R4 mRNA in human colonic adenocarcinoma cell lines by RT-PCR. A 612-bp human TRAIL-R3-specific sequence, a 453-bp TRAIL-R4-specific sequence, and an 838-bp β-actin sequence were amplified from total RNA isolated from human colonic adenocarcinoma cell lines, separated by agarose gel electrophoresis, and visualized by ethidium bromide staining.
