We are particularly interested in the translation of novel insights into the biology of MM-induced bone disease into therapies for patients and employ a variety of complementary in vitro and in vivo approaches. As part of this effort and in collaboration with other groups, we are currently refining existing mouse models of cancer-induced bone diseases (primarily MM and breast cancer) as well as developing and characterizing newer models that are better at predicting anti-tumor and anabolic bone efficacy of novel compounds. An example of this is the Radl 5T model of MM that we developed that replicates many of the features seen in the human disease. In this model, when murine 5TGM1 myeloma cells genetically engineered to express either green fluorescent protein (GFP) or luciferase are injected intravenously in naïve syngeneic C57BL/kaLwRijHsd mice, they home to the skeleton where they form tumors in the medullary cavities (Oyajobi et al., 2007).
Dr. Oyajobi teaches on, and co-directs the Interdisciplinary Human Gross Anatomy Course (CSBL 5022) for students in the occupational therapy, physical therapy, physician assistant studies and biomedical engineering graduate programs as well as graduate students in the integrated biomedical sciences program. He is also a lecturer on other grduate school courses including the Cancer Biology Core I Course (CSBL 6068).
Dr. Oyajobi has been honored for his contributions by the CSB department with the 2013 Award for Excellence in Graduate Student Education.
