Alpha-Mangostin Suppresses the Metastasis of Human Renal Carcinoma Cells by Targeting MEK/ERK Expression and MMP-9 Transcription Activity.
α-mangostin has anti-carcinogenic effects against several cancers. We investigated the molecular mechanism of this compound on the metastasis of human renal carcinoma cells.. Cell viability was measured using the MTT assay, and cell cycle distribution using flow cytometry. A Matrigel-based assay was used to measure in vitro cell migration and invasion. MAPK-related proteins and matrix metalloproteinase (MMP)-9 and MMP-2 expression were measured by western blotting, and MMP2/-9 activities were determined by gelatin zymography. RT-qPCR and a luciferase assay were used to examine the transcriptional activity of MMP-9.. α-mangostin inhibited the migration and invasion of RCC cells in a dose-dependent manner, but had no evident cytotoxic effects. Treatment of 786-O cells with α-mangostin inhibited activation of MEK and ERK. Treatment with a specific MEK inhibitor (U0126) enhanced the inhibitory effects of α-mangostin on cell migration and invasion, and the phosphorylation of ERK and MEK. Moreover, α-mangostin inhibited the expression of the MMP-9 mRNA levels as well as the activity of MMP-9 promoter, and these suppressive effects were further enhanced by U0126.. Our results suggest that α-mangostin suppresses cell migration and invasion via MEK/ERK/MMP9 pathway, and might be a promising anti-metastatic agent against human renal cell carcinoma.
