Scientific Interests

Bone is one of the most frequent sites for breast and prostate cancers to metastasize. Primary symptoms of metastatic bone disease (MBD) include osteolysis and pain. The long-term goal of Dr. Ichiro Nishimura's laboratory is to elucidate the mechanism of MBD and to design clinically viable therapeutic modalities to alleviate the MBD symptoms.

His current projects focus on osteoclasts and peripheral sensory neurons. Osteoclasts are myeloid-derived immune cells specialized to resorb bone and have been shown to be highly activated in MBD. Nishimura's lab investigates the role of osteoclasts in MBD-related pathology as well as tumor promotion. MBD often manifests radiating pain due to cancer-induced neuropathy. His lab uses the sciatic nerve entrapment model in rats to test the effectiveness of cationized gelatin nanoparticles in order to manage painful neuropathy. The hyper-activated voltage-gated sodium channel was significantly attenuated by the nanoparticle delivery of shRNA, resulting in the prolonged pain-free behaviors. Expanding this Òproof-of-conceptÓ study, Nishimura's team is testing more translatable therapy designs.
