    Abstract:
    Timosaponin AIII (TAIII) is a type of steroidal saponins isolated from Anemarrhena asphodeloides. It was known to improve learning and memory deficits through anti-inflammatory effects. TAIII was also reported to induce autophagy preceding mitochondria-mediated apoptosis in HeLa cancer cells and inhibit the growth of human colorectal cancer cells, thus regarded as a potential candidate for anti-cancer agent. In this study, we verified apoptosis-inducing and cell-cycle-arresting effects of TAIII in A549 human non-small-cell lung cancer (NSCLC) cells. Then, we report that TAIII suppresses migration and invasion of A549 human NSCLC cells. We propose that two matrix metalloproteinases (MMPs), MMP-2 and MMP-9, which are well known to be involved in cancer-metastasis, are attenuated by the treatment of TAIII. TAIII exerts its suppressive effects on MMP-2 and MMP-9 via inhibitions of ERK1/2, Src/FAK and β-catenin signalings which are closely related with the regulations of MMP-2 and MMP-9.
