Hepatoprotective Activity of a Taurine-Rich Water Soluble Extract from Octopus vulgaris Meat
In this study, we investigated the hepatoprotective activity of the water extract derived from Octopus vulgaris meat (OM). First of all, a water extract prepared from OM (OMW) showed the high extraction yield (48.22%) and the highest taurine content (39.84%) in free amino acids. OMW exhibited the high value of reducing power, ABTS and hydrogen peroxide radical scavenging activities in dose-dependent manner. The taurine-rich OMW also led to the reduced intracellular reactive oxygen species (ROS) generation with the increased cell survival in H2O2-treated Chang liver cells. In addition, OMW decreased the apoptotic phenomenon, including the formations of apoptotic bodies and sub-G1 DNA contents by regulating the protein expressions of apoptosis-related molecules such as Bcl-2 and Bax. From these results, this study indicated the taurine-rich OMW protected hepatocytes against oxidative stress. These findings suggest that OWM may be a novel potential antioxidant resource.
