    Abstract:
    The drug albendazole (ABZ) has a positive effect against Trichinella spiralis infection and has been used for the treatment and prevention of trichinellosis in humans and animals. However, the molecular mechanism ofthe effects of ABZ on T. spiralis remains unknown. Albendazole sulfoxide (ABZSO) is the main intermediary metabolic product of ABZ, and it is often used as a substitute for ABZ in metabolism and bioavailability research. Herein, isobaric tagging reagents for relative and absolute quantification (iTRAQ)-based LC-MS/MS analysis was used to identify the effect of ABZSO on the proteome of T. spiralis muscle larvae in vitro. 3795 proteins were quantified from 22974 unique peptides. Comparative proteomics analysis displayed that 417 proteins were remarkably differentially expressed in ABZSO-treated larvae, of which 213 proteins were up-regulated and 204 proteins were down-regulated. Quantitative real-time PCR of ten randomly-selected genes verified the proteomic data. Gene ontology annotation and KEGG pathway analysis showed that most of the differentially expressed proteins were involved in cell apoptosis, signal pathway, amino acid metabolism, protein synthesis/assembly/degradation and other biological processes. This study firstly provided the comprehensive proteomics data of T. spiralis in response to ABZSO, and would help us to deeply understand the molecular mechanism of ABZSO effects on T. spiralis.
