1 Amsacrine-induced apoptosis of human leukemia U937 cells is mediated by the inhibition of AKT- and ERK-induced stabilization of MCL1. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
2 Amsacrine-induced apoptosis of U937 cells was characterized by caspase-9 and caspase-3 activation, increased intracellular Ca2+ concentration, mitochondrial depolarization, and MCL1 down-regulation. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
3 Amsacrine induced MCL1 down-regulation by decreasing its stability. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
4 Restoration of ERK phosphorylation and AKT expression abrogated amsacrine-induced MCL1 down-regulation. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
5 Moreover, MCL1 over-expression inhibited amsacrine-induced depolarization of mitochondria membrane and increased the viability of amsacrine-treated cells. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
6 Moreover, MCL1 over-expression inhibited amsacrine-induced depolarization of mitochondria membrane and increased the viability of amsacrine-treated cells. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
7 Taken together, our data indicate that amsacrine abolishes ERK- and Pin1-mediated stabilization of MCL1 and promotes GSK3beta-mediated degradation of MCL1, leading to activate mitochondria-mediated apoptosis pathway in U937 cells. Amsacrine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
