Fisheries & Aquatic Science, 2015 , 18 (1) :35-44. | Evaluation on Anticancer Effect Against HL-60 Cells and Toxicity in vitro and in vivo of the Phenethyl Acetate Isolated from a Marine Bacterium Streptomyces griseus[Reference: WebLink] | We previously identified Streptomyces griseus as an anti-cancer agent (Kim et al., 2014). In this study, we isolated compounds from S. griseus and evaluated their anticancer effect and toxicity in vitro and in vivo.
METHODS AND RESULTS:
Preparative centrifugal partition chromatography (CPC) was used to obtain three compounds, cyclo(L-[4-hydroxyprolinyl]- L –leucine], Cyclo(L-Phe-trans-4-hydroxy-L-Pro) and phenethyl acetate (PA). We chose PA, which had the highest anticancer activity, as a target compound for further experiments. PA induced the formation of apoptotic bodies, DNA fragmentation, DNA accumulation in G0/G1 phase, and reactive oxygen species (ROS) formation. Furthermore, PA treatment increased Bax/Bcl-xL expression, activated caspase-3, and cleaved poly-ADP-ribose polymerase (PARP) in HL-60 cells. Simultaneous evaluation in vitro and in vivo, revealed that PA exhibited no toxicity in Vero cells and zebrafish embryos.
CONCLUSIONS:
We revealed, for the first time, that PA generates ROS, and that this ROS accumulation induced the Bcl signaling pathway. |
