Antioxidant Effects of Short-Neck Clam (Tapes philippinarum) Water Extract Containing Taurine Against AAPH-Induced Oxidative Stress in Zebrafish Embryos

摘要

The purpose of this study was to investigate the antioxidant activities of short-neck clam water extract (SNC-WE) enriched in taurine. In the present study, the half-maximal inhibitory concentration (IC50) values of the SNC-WE for DPPH, superoxide, and alkyl radical scavenging activities determined by an electron spin resonance (ESR) spectrometer were 3.16, 1.54 and 0.58 mg/mL, respectively. Furthermore, we evaluated the inhibitory effect of taurine enriched SNC-WE against the oxidative stress induced by 2,2'-azobis dihydrochloride (AAPH) in zebrafish embryos. In the present study, we observed that taurine enriched SNC-WE significantly suppressed reactive oxygen species (ROS) production, lipid peroxidation as well as cell death in the zebrafish model. These results indicate that taurine enriched SNC-WE might have antioxidant effects in both in vitro and in vivo zebrafish model.
