The pivotal protein profile between the conjoined twins and normal mosquitofish Gambusia affinis based on iTRAQ proteomic analysis.

Abstract

The fish abnormal embryonic development has attracted public attention in the recent few years. In this study, an iTRAQ proteomic analysis of mosquitofish between conjoined twins and normal fishes is applied for the first time by using the genome database of mosquitofish. Three thousand four hundred ninety proteins were identified with 304 differentially expressed proteins (DEPs). One hundred six differentially upregulated proteins (DUPs) and 198 differentially downregulated proteins (DDPs) were identified between the conjoined twins and normal mosquitofish groups. Notably, the proteins related to lipid and proteolysis were the important GO terms for the DUPs while response to light stimulus and response to radiation were the most enriched GO terms for the DDPs. The proteins related to lysosome, apoptosis, autophagy, and phagosome were the functional KEGG pathway for the DUPs while most of the pathways were related to cardiovascular for the DDPs. This study expatiated a pivotal protein profile between the conjoined twins and normal mosquitofish which can provide a conference for fish embryonic development.
