1 Simvastatin induces NFkappaB/p65 down-regulation and JNK1/c-Jun/ATF-2 activation, leading to matrix metalloproteinase-9 (MMP-9) but not MMP-2 down-regulation in human leukemia cells. Simvastatin matrix metallopeptidase 9 Homo sapiens
2 Simvastatin induces NFkappaB/p65 down-regulation and JNK1/c-Jun/ATF-2 activation, leading to matrix metalloproteinase-9 (MMP-9) but not MMP-2 down-regulation in human leukemia cells. Simvastatin matrix metallopeptidase 9 Homo sapiens
3 The aim of the present study was to explore the signaling pathways associated with the effect of simvastatin on matrix metalloproteinase-2 (MMP-2)/MMP-9 expression in human leukemia K562 cells. Simvastatin matrix metallopeptidase 9 Homo sapiens
4 In sharp contrast to its insignificant effect on MMP-2, simvastatin down-regulated MMP-9 protein expression and mRNA levels in K562 cells. Simvastatin matrix metallopeptidase 9 Homo sapiens
5 Over-expression of Pin1 suppressed simvastatin-induced MMP-9 down-regulation. Simvastatin matrix metallopeptidase 9 Homo sapiens
6 Simvastatin treatment also suppressed MMP-9 but not MMP-2 expression in human leukemia U937 and KU812 cells. Simvastatin matrix metallopeptidase 9 Homo sapiens
7 Taken together, our data indicate that simvastatin-induced p65 instability leads to MMP-9 down-regulation in leukemia cells, while simvastatin-induced JNK1/c-Jun/ATF-2 activation maintains the MMP-2 expression underlying p65 down-regulation. Simvastatin matrix metallopeptidase 9 Homo sapiens
