Research Interests:

Cancer is one of the most devastating diseases in the world and is the second leading cause of death in the United States. Despites significant effort to find cures for cancer, such as pancreatic, lung and ovarian, curative therapy still remain elusive. These three types of cancers contribute to more than 42% of overall cancer-related deaths.
  
The Tumor Physiology Laboratory directed by Dr. Masaaki Tamura, a member of The Johnson Cancer Research Center, aims to find cures for cancers by studying cell-targeted nanoparticle-based gene therapy, metastatic tumor-targeted stem cell therapy, and diet-based alternative medicine for cancer immune therapy/prevention. The core concept of Dr. Tamura’s research is to develop non-invasive host-friendly effective therapies. Dr. Tamura’s research laboratory discovered that umbilical cord Warton’s jelly (matrix) derived stem cells, first identified in the Kansas State University College of Veterinary Medicine, can migrate to cancer tissue specifically and kill various cancer cells including breast, lung and pancreatic cancers. His research team also discovered that selective peptide nanoparticles are an exceptionally good gene delivery tool in cancer animal models and this particle-dependent gene therapy markedly attenuated lung cancer growth in mice. Dr. Tamura’s lab is committed to contributing to the ongoing research for finding curative therapies to help in the fight against this difficult disease.
