- Abstract
- 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 as a potential anti-cancer agent for various human cancers. Here in this study, we report that emetine inhibits migration and invasion of human non-small-cell lung cancer (NSCLC) cells. Modulation of three major mitogen-activated protein kinases (MAPKs), ERR, p38 and JNK, is well known to be involved in regulation of matrix metalloproteinases (MMPs), which are essential in tissue remodeling and extracellular matrix (ECM) degradation, for cancer cells to spread out from the origin of tumorigenesis. Emetine regulates two major MAPKs, p38 and ERR. Differential inhibition/stimulation of ERR and p38 induced differential suppressions of beta-catenin and c-myc transcription factors. This leads to the selective down-regulation of MMP-2 and MMP-9, two major gelatinases which can degrade ECM components, and RECK, a negative regulator of MMP-9. (C) 2015 Elsevier Ireland Ltd.
