Abstract

Rubus coreanus Miquel (RCM) is used to promote prostate health and has been shown to have antioxidant and anti-carcinogenic activities. However, the effects and mechanisms of RCM on prostate cancer metastasis remain unclear. PC-3 and DU 145 cells were treated with ethanol or water extract of unripe or ripe RCM and examined for cell invasion, migration, and matrix metalloproteinases (MMPs) activity and expression. Phosphoinositide 3-kinase (PI3K) and Akt activities were examined. Unripe RCM extracts exerted significant inhibitory effects on cell migration, invasion, and MMPs activities. A significant reduction in MMPs activities by unripe RCM ethanol extract treatment (UE) was associated with reduction of MMPs expression and induction of tissue inhibitors of metalloproteinases (TIMPs) expression. Furthermore, PI3K/Akt activity was diminished by UE treatment. In this study, we demonstrated that UE decreased metastatic potential of prostate cancer cells by reducing MMPs expression through the suppression of PI3K/Akt phosphorylation, thereby decreasing MMP activity and enhancing TIMPs expression.
