title: Proteomic analysis of altered proteins in lymphoid organ of yellow head virus infected Penaeus monodon.
abstract: A comparative proteomic analysis was employed to identify altered proteins in the yellow head virus (YHV) infected lymphoid organ (LO) of Penaeus monodon. At 24 h post-infection, the infected shrimps showed obvious signs of infection, while the control shrimps remained healthy. Two-dimensional electrophoresis of proteins extracted from the LO revealed significant alterations in abundance of several proteins in the infected group. Protein identification by MALDI-TOF MS and nanoLC-ESI-MS/MS revealed significant increase of transglutaminase, protein disulfide isomerase, ATP synthase beta subunit, V-ATPase subunit A, and hemocyanin fragments. A significant decrease was also identified for Rab GDP-dissociation inhibitor, 6-phosphogluconate dehydrogenase, actin, fast tropomyosin isoform, and hemolymph clottable protein. Some of these altered proteins were further investigated at the mRNA level using real-time RT-PCR, which confirmed the proteomic data. Identification of these altered proteins in the YHV-infected shrimps may provide novel insights into the molecular responses of P. monodon to YHV infection.
