Background: It has been shown that the non-opioid effects of Met-enkephalin, which is derived from proenkephalin-A, are mediated through a specific opioid growth factor (OGF) receptor which is assumed to be involved in the control of cell growth. The expression and tissue location of proenkephalin-A mRNA in the gastrointestinal tract remains largely unknown. Methods: In this study we have analyzed the expression of proenkephalin-A mRNA in the human esophagus, gastrointestinal tract and surrounding organs by means of reverse-transcriptase PCR (RT-PCR). Results: The present study demonstrates proenkephalin-A mRNA expression in the human esophagus, gastrointestinal tract, pancreas, and gallbladder. Conclusion: The present study demonstrates proenkephalin-A mRNA expression in regions of the human esophagus, gastrointestinal tract, pancreas, and gallbladder tissues which provides information for the future mapping of proenkephalin-A mRNA and protein expression/co-expression at the cellular level.
