摘要: Emetine is a natural compound originated from ipecac roots. It was commonly used as anti-protozoal and vomiting agent. The apoptosis-inducing effect of emetine makes it considered potential anti-cancer agent for various human cancers. Here in this study, we report that inhibits migration invasion non-small-cell lung cancer (NSCLC) cells. Modulation three major mitogen-activated protein kinases (MAPKs), ERK, p38 JNK, well known to be involved regulation matrix metalloproteinases (MMPs), which are essential tissue remodeling extracellular (ECM) degradation, cells spread out the origin tumorigenesis. regulates two MAPKs, ERK. Differential inhibition/stimulation ERK induced differential suppressions β-catenin c-myc transcription factors. This leads selective down-regulation MMP-2 MMP-9, gelatinases can degrade ECM components, RECK, negative regulator MMP-9.
