Abstract

Background: Despite more than 30 years after utilization of sulfur mustard or bis (2-chloroethyl) sulfide (SM) by Iraqi troops against Iranian military members and civilians, there are a lot of reported delayed complications for the exposed people. Nonetheless, the molecular mechanism of action from this chemical warfare agent is not recognized yet. Material and method: In this study, we employed two dimensional gel electrophoresis (2DE) technique to investigate the serum proteins from chemical exposed people compared to non-exposed individuals to provide an inside into molecular mechanism of this chemical agent. Each group was divided into two subgroups including individuals with, and without respiratory complications. For each group, 10 individuals were included after informed consent. Result: The results showed protein spots, which were exclusively/mainly expressed in chemical exposed patients with complications, including T cell receptor alpha, and hematopoietic cell signal transducer. Also there were protein spots that were expressed only in all exposed groups (with and without complications). On the other hand, we could identify protein spots that were exclusively expressed/altered only in non-exposed group with complications including Pre T-cell antigen receptor, CD40 ligand, and multidrug and toxin extrusion proteins. Conclusion: Our investigation could result in identification of proteins that are associated to chemical exposure, as well as those specific for respiratory complications irrespective of chemical exposure. These candidate proteins can be used as biomarker, as well as a base for understanding the molecular mechanism of this chemical agent. © 2020 Elsevier B.V.
