چکیده انگلیسی
Cellular oxidative stress responses are caused in many ways, but especially by disease and environmental stress. After the initial burst of reactive oxygen species (ROS), the effective elimination of ROS is crucial for the survival of organisms and is mediated by antioxidant defense mechanisms. In this paper, we investigate the possible antioxidant function of Penaeus monodon Receptor for Activated C Kinase-1 (Pm-RACK1). When Pm-RACK1 was over-expressed in Escherichia coli cells or Spodoptera frugiperda (Sf9) insect cells exposed to H2O2, it significantly protected the cells from oxidative damage induced by H2O2. When recombinant Pm-RACK1 protein was expressed as a histidine fusion protein in E. coli and purified with a Ni2+-column it possessed antioxidant functions that protected DNA from metal-catalyzed oxidation. Shrimp (Penaeus vannamei) held at an alkaline pH had a much higher hepatopancreatic expression of Pm-RACK1 than in those held at pH 7.4. The exposure of shrimp to alkaline pH is also known to increase ROS production. These results provide strong evidence that Pm-RACK1 can participate in the shrimp antioxidant response induced by the formation of ROS.
