Raya Saab
Lindhard Family Professor of Pediatric Cancer Biology
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. -

Clinical Assistant Professor, Adult Neurology
BioZahra Sadat-Hossieny, MD, is a board-certified neurologist who completed her fellowship in clinical epilepsy at Stanford University Hospitals and Clinics. She finished her residency in neurology at the Ohio State University Wexner Medical Center. She obtained her medical degree and a certificate in global health from the George Washington University School of Medicine and Health Sciences.
She has extensive experience treating patients with epilepsy and currently provides care through the Comprehensive Epilepsy and Comprehensive Neurology Programs at Stanford Health Care. In addition to her clinical responsibilities, Dr. Sadat-Hossieny also teaches future generations of clinicians as an assistant professor at Stanford School of Medicine in the Department of Neurology, Epilepsy, and Comprehensive Neurology.
Dr. Sadat-Hossieny has authored several peer-reviewed journal articles and book chapters. She has presented her research orally and through posters at various conferences. During her fellowship at Stanford University Hospitals and Clinics, she used advanced diagnostic techniques including video-EEG monitoring, computerized brainwave mapping, diagnostic imaging, neuropsychiatric testing, and functional mapping to accurately diagnose epilepsy and conditions imitating epilepsy. She also gained expertise in the most advanced forms of epilepsy treatment including neuromodulation, epilepsy surgery and medications specific to epilepsy. Her research focused on the cognitive effects of anti-seizure medications on patients with epilepsy and their children. She has also published on the importance of nutrient supplementation on cognition in patients taking anti-seizure medications. Her collaborations include projects that assess and improve patients’ understanding of their own seizure types. -
