:
Knockdown studies using siRNAs to TRAIL, DR5, JNK and CHOP as well as chemical inhibitors of ER stress and caspase-8 showed that : i ) alpha-TEA activation of
DR5/caspase-8 induces an ER stress mediated JNK/CHOP/DR5 positive amplification loop ; ii ) alpha-TEA downregulation of c-FLIP ( L ) protein levels is mediated by JNK/CHOP/DR5 loop via a JNK dependent Itch E3 ligase ubiquitination that further serves to enhance the JNK/CHOP/DR5 amplification loop by preventing c-FLIP 's inhibition of caspase-8 ; and ( iii ) alpha-TEA downregulation of Bcl-2 is
mediated by the ER stress dependent
JNK/CHOP/DR5 signaling
