Lawrence Recht, MD
Professor of Neurology and Neurological Sciences (Adult Neurology) and, by courtesy, of Neurosurgery
Current Research and Scholarly InterestsOur laboratory focuses on two interrelated projects: (1) assessment of glioma development within the framework of the multistage model of carcinogenesis through utilization of the rodent model of ENU neurocarcinogenesis; and (2) assessment of stem cell specification and pluripotency using an embryonic stem cell model system in which neural differentiation is induced.

Raya Saab
Lindhard Family Professor of Pediatric Cancer Biology
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. -
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.

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
Professor of Cardiothoracic Surgery
On Leave from 02/03/2025 To 05/30/2025Current 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. -
