    Raya Saab

    Professor of Pediatrics (Hematology/Oncology)

    BioOur laboratory focuses on investigating molecular mechanisms of oncogene-induced tumorigenesis and tumor suppressor pathways, and oncogenic signaling in the pediatric solid tumor rhabdomyosarcoma. Our earlier work identified the tumor suppressors p53 and p18Ink4c as inhibitors of Cyclin D1-driven tumorigenesis in a pineoblastoma model, through senescence induction, and highlighted distinct roles for the the RB and p53 pathways in induction and maintenance of oncogene-induced senescence. We also identified CDK2 as a potential target for inducing senescence in premalignant lesions to inhibit tumor progression.
    Our current focus is on studying oncogenic signaling and tumor suppression in the childhood tumor rhabdomyosarcoma, to identify key mediators of invasion and metastasis, which is the most common cause of treatment failure clinically. We use preclinical in vitro and in vivo models, including murine and human cell lines, and mouse models of disease.
    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.

  • Shagufta Shaheen

    Shagufta Shaheen

    Clinical Assistant Professor, Medicine - Oncology

    BioDr. Shaheen specializes in the gastrointestinal malignancies and she has expertise in treating neuroendocrine tumors (NETs). Following her fellowship in Hematology and Oncology, Dr Shaheen completed an advanced fellowship in Neuroendocrine tumors from Stanford University. The NET advanced fellowship is first of its kind in United State started under the leadership of Dr Pamela Kunz who is the founding Director of the Stanford Neuroendocrine Tumor Program established in 2015. After completing her advanced fellowship, Dr Shaheen joined Stanford Oncology division as Clinical Assistant Professor. Dr Shaheen is involved in further developing the neuroendocrine oncology program at Stanford which serves as a centre of excellence in the treatment of neuroendocrine tumors. Dr Shaheen is actively involved in clinical research and clinical trials. Dr Shaheen is also involved in taking care of patients admitted to the oncology service as well as resident and fellow teaching.

  • Joseph Shrager

    Joseph Shrager

    Professor of Cardiothoracic Surgery

    Current Research and Scholarly InterestsIn clinical research, Dr. Shrager studies outcomes in a variety of areas within Thoracic Surgery including: parenchyma-sparing operations and minimally invasive resections for lung cancer, transcervical thymectomy for myasthenia gravis, diaphragm plication, and surgical treatment of emphysema.

    Dr. Shrager's lab is focused on the impact of disease states upon the diaphragm. His group published the seminal paper (NEJM) describing diaphragm atrophy assoc'd with mechanical ventilation.

  • Eila C. Skinner

    Eila C. Skinner

    Thomas A. Stamey Research Professor of Urology

    Current Research and Scholarly InterestsMy research focuses on outcomes in the treatment of muscle invasive and high-grade non-muscle invasive bladder cancer. This includes identifying markers of prognosis, predictive markers for response to surgery and chemotherapy, and working toward an individualized, multidisciplinary approach to disease management. I have also focused on optimizing the use of lower urinary tract reconstruction in patients undergoing cystectomy, and developing interventions to improve patient quality of life.
