摘要	Antioxidant enzymes, such as glutathione peroxidase (GPx), catalase (CAT), and peroxiredoxin (Prx), are essential components in cells to eliminate excessive reactive oxygen species such as hydrogen peroxide (H2O2). GPx, CAT, and Prx genes have been reported in penaeid shrimp, and they showed different expression profiles at transcription or protein level when shrimps were challenged by microbes. In order to learn the relationship among the above three genes in their function, GPx, CAT, and Prx transcripts were analyzed, and the variation of GPx and CAT enzyme activity was detected when shrimp was injected with H2O2 or one antioxidant enzyme gene was silenced in shrimp by double-strand RNA injection. The results indicated that there existed some relationships among three antioxidant enzyme genes, CAT, GPx, and Prx in shrimp at transcriptional level. The transcription of CAT and GPx could be directly induced by H2O2 injection, while the transcription of Prx cannot be induced by H2O2. Decreased transcription level of CAT or GPx could lead to increased transcription of the other two genes, which suggested that there existed some compensation among these three antioxidant enzyme genes. These data can help us to understand the roles of antioxidant enzymes in crustacean.
