MSLN (mesothelin), a secreted protein that is overexpressed in ovarian cancer tissues with a poor clinical outcome, has been previously identified to activate PI3K (phosphoinositide 3-kinase)/Akt signalling and inhibit paclitaxel-induced apoptosis. The present study investigates the correlation between MSLN and MMP (matrix metalloproteinase)-7 in the progression of ovarian cancer, and the mechanism of MSLN in enhancing ovarian cancer invasion. The expression of MSLN correlated well with MMP-7 expression in human ovarian cancer tissues. Overexpressing MSLN or ovarian cancer cells treated with MSLN showed enhanced migration and invasion of cancer cells through the induction of MMP-7. MSLN regulated the expression of MMP-7 through the ERK (extracellular-signal- regulated kinase) 1/2, Akt and JNK (c-Jun N-terminal kinase) pathways. The expression of MMP-7 and the migrating ability of MSLN-treated ovarian cancer cells were suppressed by ERK1/2-or JNK-specific inhibitors, or a decoy AP-1 (activator protein 1) oligonucleotide in in vitro experiments, whereas in vivo animal experiments also demonstrated that mice treated with MAPK (mitogen-activated protein kinase)/ERK- or JNK-specific inhibitors could decrease intratumour MMP-7 expression, delay tumour growth and extend the survival of the mice. In conclusion, MSLN enhances ovarian cancer invasion by MMP-7 expression through the MAPK/ERK and JNK signal transduction pathways. Blocking the MSLN-related pathway could be a potential strategy for inhibiting the growth of ovarian cancer. ? The Authors Journal compilation ? 2012 Biochemical Society. |
