Matrix metalloproteinase-9 (MMP-9) plays an important role in the invasion and metastasis of cancer cells. In this study, we examined the inhibitory effect of silibinin, a flavonoid antioxidant from milk thistle (Silybum marianum L.) on PMA-induced MMP-9 expression in MCF-7 human breast carcinoma cells. Silibinin significantly and selectively suppressed(More)
Matrix metalloproteinase-9 (MMP-9) plays an important role in the invasion and metastasis of cancer cells. In this study, we examined the inhibitory effect of bee venom (BV) and its major peptides, melittin and apamin, on PMA-induced invasion induced by MMP-9 expression in Caki-1 renal cancer cells. BV and melittin, but not apamin, significantly suppressed(More)
OBJECTIVE Melittin (MEL), a major component of bee venom, has been associated with various diseases including arthritis, rheumatism and various cancers. In this study, the anti-angiogenic effects of MEL in CaSki cells that were responsive to the epidermal growth factor (EGF) were examined. METHODOLOGY/PRINCIPAL FINDINGS MEL decreased the EGF-induced(More)
Bee venom is a natural compound produced by the honey bee (Apis mellifera), and has been reported as having the biological and pharmacological activities, including anti-bacterial, anti-viral and anti-inflammation. In the present study, the inhibitory effects of bee venom and its major peptide components on the tumor invasion were demonstrated. It was(More)
Bee venom is a natural ingredient produced by the honey bee (Apis mellifera), and has been widely used in China, Korea and Japan as a traditional medicine for various diseases such as arthritis, rheumatism, and skin diseases However, the regulation of the underlying molecular mechanisms of the anti-arthritis by bee venom and its major peptides is largely(More)
Matrix metalloproteinases-9 (MMP-9) plays an important role in the pathogenesis of atherosclerosis and migration of vascular smooth muscle cells (VSMCs) after an arterial injury. In this study, we investigated the potential molecular mechanisms underlying the anti-atheroscleroic effects of melittin, a major component of bee venom, in human aortic smooth(More)
Renal fibrosis is characterized by the excessive accumulation of extracellular matrix (ECM) proteins such as type I collagen, fibronectin, and by the increased expression of PAI-1. This study evaluated the anti-fibrotic effect of bee venom and its major compounds (melittin and apamin) on TGF-β-induced pro-fibrotic gene expression. Bee venom and melittin(More)
Matrix metalloproteinase-9 (MMP-9) plays a major role in the pathogenesis of atherosclerosis and restenosis by regulating both migration and proliferation of vascular smooth muscle cells (VSMC) after an arterial injury. In this study, we examined the inhibitory effect of three major flavonoids in Scutellariae Radix, baicalin, baicalein, and wogonin, on(More)
Hypoxia-inducible factor (HIF)-1 plays an important role in tumor progression, angiogenesis and metastasis. In this study, we investigated the potential molecular mechanisms underlying the anti-angiogenic effect of ascofuranone, an isoprenoid antibiotic from Ascochyta viciae, in epidermal growth factor (EGF)-1 responsive human breast cancer cells.(More)
Matrix metalloproteinase-9 (MMP-9) plays an important role in the invasion and metastasis of cancer cells. In this study, we examined the inhibitory effect of capillarisin, a bioactive flavonoid of Artemisia capillaries, on phorbol myristate acetate (PMA)-induced MMP-9 expression in MCF-7 human breast carcinoma cells. Capillarisin significantly and(More)
