| Research Abstract |
We established the animal model of bone cancer pain by the injection of MRMT-1(rat mammary gland carcinoma cells) into the tibia bone. In the MRMT-1 group, expression of total BDNF mRNA increased significantly compared to the sham group. Immunohistochemistry revealed that MRMT-1 treatment increased the proportion of small BDNF-immunoreactive neurons in the L3 DRG. The suppression of BDNF mRNA and protein may attenuate bone cancer pain in the model.
