    BioI am a pediatric oncologist, and I primarily treat children who are diagnosed with soft tissue sarcomas including rhabdomyosarcoma, and children diagnosed with the eye tumor retinoblastoma, as well as children with other solid tumors.
    I have two very different areas of primary research interest, both of which I pursue with passion. One focuses on global oncology, including clinical and research resource capacity building towards effective treatment and improving outcomes of children with cancer worldwide. I work with collaborators across the globe towards a common goal of improving access to diagnostic and clinical care, training of multidisciplinary teams, and building clinical resources and research capacity to develop context-informed approaches to improving cancer care and achieving better outcomes for children diagnosed with cancer irrespective of where they happen to live.
    My parallel research interest, which is the focus of my laboratory, is understanding oncogenic signaling in pediatric soft tissue sarcomas, in an effort to clarify the driving biology and determinants of metastatic disease, to uncover novel targets for more effective treatment. We use preclinical in vitro and in vivo models, including murine and human cell lines, and mouse models of cancer. We have recently uncovered a paracrine role for rhabdomyosarcoma-secreted exosomes in impacting biology of stromal cells. Rhabdomyosarcoma-derived exosomes carry specific miRNA cargo that imparts an invasive and migratory phenotype on normal recipient fibroblasts, and proteomic analysis revealed specific and unique pathways relevant to the two different molecular rhabdomyosarcoma subtypes that are driven by distinct oncogenic pathways. We identified that the driver oncogene in fusion-positive rhabdomyosarcoma, PAX3-FOXO1, modulates exosome cargo to promote invasion, migration, and angiogenic properties, and identified specific microRNA and protein cargo acting as effectors of PAX3-FOXO1 exosome-mediated signaling, including modulation of oxidative stress response and cell survival signaling. Our ongoing work is focused on interrogating specific paracrine signaling pathways and molecular mechanisms of metastatic disease progression in rhabdomyosarcoma, for potential therapeutic targeting.

  • Julien Sage

    Julien Sage

    Elaine and John Chambers Professor of Pediatric Cancer and Professor of Genetics

    Current Research and Scholarly InterestsWe investigate the mechanisms by which normal cells become tumor cells, and we combine genetics, genomics, and proteomics approaches to investigate the differences between the proliferative response in response to injury and the hyperproliferative phenotype of cancer cells and to identify novel therapeutic targets in cancer cells.

  • Kathleen M. Sakamoto

    Kathleen M. Sakamoto

    Shelagh Galligan Professor in the School of Medicine

    Current Research and Scholarly InterestsMy research focuses on the molecular pathways that regulate normal and aberrant blood cell development, including acute leukemia and bone marrow failure syndromes. We are also studying novel drugs for treatment of cancer.

  • Christy Sandborg

    Christy Sandborg

    Professor of Pediatrics (Rheumatology), Emerita

    Current Research and Scholarly InterestsThe major emphasis of my work in the past 2 decades has been focused on the future of academic pediatrics and pediatric rheumatology through providing training, research opportunities and environments to nurture and challenge future pediatric rheumatologists and subspecialists. In parallel in the last decade, my scope has included to workforce and physician wellbring, patient and family centered care--and more recently, diversity, equity and inclusion, and health equity.
