TNFSF10 and infection: Immunoblotting and ELISA assays also confirmed thatAd-TRAIL-MRE-1-133-218 infection resulted in TRAIL expression with a comparativelevel with Ad-TRAIL, but almost no TRAIL expression was detected in normalbladder mucosal cells infected with Ad-TRAIL-MRE-1-133-218 (Figure 1c and d).
