Research Abstract

Growth plate and bone radioprotection and radiorecovery

Our laboratory has been funded continuously by the NIH since 2000 for our work evaluating the mechanisms of damaging effects of irradiation on bone growth.  Most recently, the focus has been on selective stimulation of radiorecovery pathways.  This work involves in vitro and in vivo work with histomorphometric, immunohistochemical, and molecular evaluation at the RNA and protein level.  This area of research is relevant to children being treated for bone and soft-tissue sarcomas.

Osteosarcomas

Utilizing both in vitro and in vivo work including an orthotopic intraosseous osteosarcoma injection model, differential expression of genes and pathways  related to metastatic potential are being evaluated.

Chemotherapy related osteoporosis

Our laboratory has established the high prevalence of premature low bone mineral density in young adults following chemotherapy for pediatric malignancies, including bone and soft-tissue sarcomas. However, the specific mechanisms of this adverse outcome have not been elucidated. Furthermore, the precise role of specific novel agents in the simultaneous treatment of osteosarcoma and low bone mineral density has yet to be explored, leaving room for exploration and development of new treatments.

Radiation associated fractures

Building upon our extensive experience exploring the damaging effects of irradiation treatments on growth plate function in pediatric patients with malignant bone and soft-tissue tumors, an in vivo nude mouse model has been established to evaluate the more common problem of fracture following bone irradiation.  This problem spans numerous specialties, including gynecologic oncology, where pelvic irradiation frequently leads to pelvic stress fractures, as well as pediatric oncology, adult oncology, radiation oncology, and orthopedics.
