Abstract Endogenous opioid peptides have an essential role in the intrinsic modulation and control of inflammatory pain which could be therapeutically useful. In this study we established a muscular electroporation method for the gene transfer of proopiomelanocortin POMC in vivo and investigated its effect on inflammatory pain in a rat model of rheumatoid arthritis. The gene encoding human POMC was inserted into a modified pCMV plasmid and 0-200 ig of the plasmid-POMC DNA construct was transferred into the tibialis anterior muscle of rats treated with complete Freund s adjuvant CFA with or without POMC gene transfer by the electroporation method. The safety and efficiency of the gene transfer was assessed with the following parameters thermal hyperalgesia serum adrenocorticotropic hormone .
