SYKT Alleviates Doxorubicin-Induced Cardiotoxicity via Modulating ROS-Mediated p53 and MAPK Signal Pathways

Figure 3

SYKT inhibits DOX-induced MAPK activation. (A) DOX induces p38/JNK MAPK activation in a time-dependent manner. (B) DOX-mediated p38/JNK MAPK activation is inhibited by SB 203580/SP600125 and by SYKT. The cardiomyocytes were treated with SB 203580/SP600125 prior to DOX (1 μM for 30 min) addition. β-Actin was used as an internal control. ap < 0.05 versus control; bp < 0.05 versus DOX; n = 6.
