| Outline of Final Research Achievements |
We established the new cancer pain model in rats to investigate new treatment for the cancer pain. Furthermore, this study evaluated the effects of POMC (proopiomelanocortin, the precursor for β-endorphin, an endogenous opioid) gene transfection using radial shock waves (RSWs). We used mainly two models; neuropathic pain model, cancer pain model. POMC gene transfection suppressed CGRP expression in the DRGs, microglial activation in the dorsal horn of the spinal cord, and pain behavior These findings suggest the effectiveness of POMC gene transfection using RSWs for the treatment of neuropathic pain, and cancer pain, without side effects for a long time.
