| Outline of Final Research Achievements |
1. Brain-derived neurotrophic factor (BDNF) plays an important role in the pathological pain state in some pain models including bone cancer pain. Changes in BDNF in dorsal root ganglia (DRG) were studied in a rat bone cancer pain model. BDNF was increased in L3 DRG after intra-tibial inoculation of MRMT-1 rat breast cancer cells.
2. Decoy DNAs for BDNF exon1 not effective for pain relief derived from cancer. These results suggested that development of cancer pain were different mechanisms from neuropathic pain.
