Abstract
Litopenaeus vannamei (Pacific white shrimp) is one of the most commercially important varieties of shrimp cultivated in the world. Shrimp farming is a high-risk, capital-intensive industry that is susceptible to periodic outbreaks of diseases caused by viral and bacterial pathogens. Thus, there is a need to develop economically viable methods of disease control. The hepatopancreas of crustaceans are known to have an important role in their innate immune response. In this study, we have explored the immune response of the hepatopancreas from L. vannamei fed with trans-vp28 gene Synechocystis sp. PCC6803 using iTRAQ-based proteomics. A total of 214 differentially expressed proteins (DEPs) were identified, of which 143 were up-regulated and 71 were down-regulated. These proteins have diverse roles in the cell cytoskeleton and cell phagocytosis, antioxidant defense process and the response of immune related proteins. Among these proteins, the immunity associated with the functional annotation of L. vannamei was further analysed. In addition, 4 DEPs (act1, N/A, H and C7M84_013542) were analysed using parallel reaction monitoring (PRM). This is the first report of proteomics in the hepatopancreas of L. vannamei immunized with trans-vp28 gene Synechocystis sp. PCC6803.
