Effects of sFas gene delivery on myocardial expression of JNK, c-Jun, ERK, p-38 MAPK, and IκB and of their respective phosphorylated forms in doxorubicin cardiotoxicity. Western blots for JNK, p-JNK, c-Jun, and p-Jun (A); ERK and p-ERK (B); p38 and p-p38 (C); and IκB and p-IκB (D) with the densitometric analyses. *P < 0.05 versus the sham group; #P < 0.05 versus the doxorubicin-treated group with LacZ gene transfer.
