[The research of proteome profiling change of 1-bromopropane poisoning cases]

Objective: This study was mainly focused on styudy on he proteome profile change between exposure to 1-Bromopropane (1-BP) and 1-BP poisoning. Methods: The samples of serums from exposure to 1-BP and 1-BP poisoning were collected and analyzed through Label free proteome technology platform. The differently expressed proteins between the two groups were quantified and identified, followed by function analysis by bioinformatics. Results: 127 proteins over 2 fold-change were selected, in which 39 proteins were up-regulated and 88 proteins were down-regulated. These different-ly expressed proteins were mainly involved in the process of enzyme active regulation, inflammatory reaction, protein modification, stress response, coagulation, transport. Conclusion: The differently expressed proteins provided the potential protein biomarkers for the early diagnosis of 1-BP poisoning and was beneficial for clinical diagnosis of 1-BP and understanding of the mechanism of 1-BP poisoning.
