Dr. Kelly Makielski and Dr. Jaime Modiano from the University of Minnesota join us on OsteoBites to discuss comparative extracellular vesicle (EV) biomarkers for osteosarcoma risk and prognosis.

They are investigating extracellular vesicle (EV) transcriptomic profiles as minimally invasive biomarkers in canine and pediatric osteosarcoma in two ongoing studies. In the Canine Osteosarcoma Early Detection (COED) study, they are sequencing EV RNA from otherwise healthy dogs in breeds at elevated risk of osteosarcoma to identify gene signatures for the early detection and risk assessment of osteosarcoma. In parallel, they are conducting the KIDsCAN study, where we are sequencing EVs from pediatric osteosarcoma patients to identify prognostic signatures that could ultimately guide treatment intensity, aiming to minimize long-term therapy-associated morbidity without negatively impacting survival. Preliminary results from COED will be shared, along with how their comparative approach is helping to guide the KIDsCAN study.

Kelly M. Makielski, DVM, DACVIM (SAIM) is an Assistant Professor of Small Animal Internal Medicine at the University of Minnesota College of Veterinary Medicine and Masonic Cancer Center. Her research focuses on extracellular vesicle (EV) biology and comparative oncology, using naturally occurring cancers in dogs to inform human cancer biology and treatment. She is the recipient of an NIH K01 investigating EV–based biomarkers for osteosarcoma prognosis in pediatric osteosarcoma, to guide personalized therapy and reduce treatment-related morbidity.

Dr. Jaime Modiano holds the Alvin and June Perlman Endowed Chair of Animal Oncology and is director of the Animal Cancer Care and Research Program of the College of Veterinary Medicine and the Masonic Cancer Center, University of Minnesota. He completed his training through the Veterinary Medical Scientist Training Program (VMD, PhD) at the University of Pennsylvania, and he followed it with a residency in Clinical Pathology at Colorado State University and a post-doctoral fellowship at the National Jewish Center for Immunology and Respiratory Medicine. Before joining the University of Minnesota, he served on the faculties of Texas A&M University and the University of Colorado Health Sciences Center. Dr. Modiano has also worked in the private sector, as founder of several start-up companies, and as Director of Cancer Immunology and Immunotherapy for the Donald Monk Cancer Research Foundation. Through his research, Dr. Modiano seeks to understand how and why cancer happens and to develop strategies for improving the health and well-being of companion animals and humans alike.
