Proteomic analysis of individual giant freshwater prawn, Macrobrachium rosenbergii, growth retardants

“Iron prawn” is a condition of severe growth retardation that fishers call. The giant river prawn (Macrobrachium rosenbergii) commercially important species contains high protein content and functional nutrients. However, no proteomic information available for this species. We performed the shotgun 2DLC-MS/MS analysis total from “iron prawn”. Total 19,758 peptides corresponding to 2613 high-confidence proteins were identified. These range in size 40 70 kDa. KEGG revealed largest group consisting 102 pathway comparing with normal prawn. Additionally, 7, 11, 1, 6, 5 enzymes found eyestalk, liver, muscle, ovary, testis, respectively. functions these differently expressed include immune system action against pathogens, muscle contraction, digestive metabolism, cell differentiation, migration, apoptosis Our work provides insight into understanding formation mechanism
