1 We found that CBG caused the significant activation of ERK, JNK and p38 MAPK in U266 cells. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
2 Inhibition of ROS generation by N-acetyl-l-cysteine (NAC) significantly prevented CBG-induced ERK, JNK and p38 MAPK activation and apoptosis. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
3 Inhibition of ROS generation by N-acetyl-l-cysteine (NAC) significantly prevented CBG-induced ERK, JNK and p38 MAPK activation and apoptosis. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
4 Interestingly, ERK, JNK and p38MAPK pharmacological inhibitors blocked CBG-induced MAPKs activation and ERK inhibitor (PD98059) also prevented the CBG-induced caspase-3 activation and PARP cleavage in U266 cells. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
5 Interestingly, ERK, JNK and p38MAPK pharmacological inhibitors blocked CBG-induced MAPKs activation and ERK inhibitor (PD98059) also prevented the CBG-induced caspase-3 activation and PARP cleavage in U266 cells. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
6 Interestingly, ERK, JNK and p38MAPK pharmacological inhibitors blocked CBG-induced MAPKs activation and ERK inhibitor (PD98059) also prevented the CBG-induced caspase-3 activation and PARP cleavage in U266 cells. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
7 Taken together, these findings suggest that CBG can act as a potent anticancer agent against MM and possibly exerts its effects through the ROS-mediated activation of ERK, JNK and p38 MAPK leading to the activation of caspase-3 in U266 cells. cinobufagin mitogen-activated protein kinase 1 Homo sapiens
