Each reported value represents the mean fold of mRNA expression relative to the control levels for three biological replicates. FADD, Fas-associated death domain protein; SF, sodium ferulate; TNFR, tumor necrosis factor receptor; TRADD, TNF receptor-associated death domain; TRAF, TNF receptor-associated factor.
