Abstract
Pleurotus tuber-regium (Fries) Singer (PTR), both an edible and medicinal mushroom also known as tiger milk mushroom, has a growing popularity and economic importance due to its flavor, nutritive value and medicinal effects. In this study, the anti-oxidant and anti-angiogenic activities of a 60% ethanol extract (EE) obtained from the sclerotium of PTR was investigated. Typical phenolic compounds including protocatechuic, chlorogenic, syringic, ferulic, folic acid were identified and quantified in EE by the HPLC-UV-ESI/MS analyses. EE possessed strong antioxidant activity and could dose-dependently inhibit vascular endothelial growth factor (VEGF)-induced human umbilical vein endothelial cells (HUVEC) migration and tube formation. qPCR results showed that VEGF-induced FGF, ANG-TIE and MMP gene expression as well as VEGFR were down-regulated at the mRNA level after treated with EE, suggesting that multiple molecular targets related to angiogenesis was involved. Furthermore, EE also inhibited the formation of sub-intestinal vessel plexus (SIVs) in zebrafish embryos in vivo. All of these suggested that EE of PTR could be the source of potential inhibitors to target angiogenesis.
