Current Research and Scholarly Interests The ANNES LABORATORY of Molecular Endocrinology: Leveraging Chemical Biology to Treat Endocrine Disorders
The prevalence of diabetes is increasing at a staggering rate. By the year 2050 an astounding 25% of Americans will be diabetic. The goal of my research is to uncover therapeutic strategies to stymie the ensuing diabetes epidemic. To achieve this goal we have developed a variety of innovate experimental approaches to uncover novel approaches to curing diabetes.
(1) Beta-Cell Regeneration: Diabetes results from either an absolute or relative deficiency in insulin production. Our therapeutic strategy is to stimulate the regeneration of insulin-producing beta-cells to enhance an individual?s insulin secretion capacity. We have developed a unique high-throughput chemical screening platform which we use to identify small molecules that promote beta-cell growth. This work has led to the identification of key molecular pathways (therapeutic targets) and candidate drugs that promote the growth and regeneration of islet beta-cells. Our goal is to utilize these discoveries to treat and prevent diabetes.
(2) The Metabolic Syndrome: A major cause of the diabetes epidemic is the rise in obesity which leads to a cluster of diabetes- and cardiovascular disease-related metabolic abnormalities that shorten life expectancy. These physiologic aberrations are collectively termed the Metabolic Syndrome (MS). My laboratory has developed an original in vivo screening platform t to identify novel hormones that influence the behaviors (excess caloric consumption, deficient exercise and disrupted sleep-wake cycles) and the metabolic abnormalities caused by obesity. We aim to manipulate these hormone levels to prevent the development and detrimental consequences of the MS.
HEREDIATY PARAGAGLIOMA SYNDROME
The Hereditary Paraganglioma Syndrome (hPGL) is a rare genetic cancer syndrome that is most commonly caused by a defect in mitochondrial metabolism. Our goal is to understand how altered cellular metabolism leads to the development of cancer. Although hPGL is uncommon, it serves as an excellent model for the abnormal metabolic behavior displayed by nearly all cancers. Our goal is to develop novel therapeutic strategies that target the abnormal behavior of cancer cells. In the laboratory we have developed hPGL mouse models and use high throughput chemical screening to identify the therapeutic susceptibilities that result from the abnormal metabolic behavior of cancer cells.
As a physician scientist trained in clinical genetics I have developed expertise in hereditary endocrine disorders and devoted my efforts to treating families affected by the hPGL syndrome. By leveraging our laboratory expertise in the hPGL syndrome, our care for individuals who have inherited the hPGL syndrome is at the forefront of medicine. Our goal is to translate our laboratory discoveries to the treatment of affected families.

Current Research and Scholarly Interests Research interests include high-risk youth, adolescent health services, and the juvenile justice system.
Clinical Associate Professor, Pediatrics
Bio I graduated from UCLA (now Geffen) School of Medicine, did my pediatrics residency at Columbia-Presbyterian in NYC, followed by a clinical fellowship in developmental (what was then called an ?ambulatory?) pediatrics at Boston Children?s Hospital. The first 28 years of my career were spent in clinical practice combining both DBP and primary care (the latter focused on serving CSHCN). During those years I was involved in numerous divide-bridging efforts - including programs to coordinate inpatient & outpatient medicine, connect tertiary & primary care, and promote teamwork between pediatricians, psychologists, nurse practitioners, and other community partners. I founded my own solo practice in 1989 and managed its growth to an 8-provider group over the next 25 years. Our practice was a founding member of the PPOC and I served on its board of directors for 6 years. The PPOC is one of the largest pediatric IPA?s in the country, with >200 member providers affiliated with Boston Children's Hospital. Over the years we were involved in groundbreaking QI initiatives including those involving asthma, weight, and ADHD management; medical home; and behavioral health integration with primary care.
I?m now well into my career's ?second act? on the clinician-educator track here at Stanford. I'm proud to have piloted our division's primary care initiative (DBPCI) and am now in the process of planning for a second phase thereof, hoping to make improved collaboration between DBP and primary care more available to more patients. I also pioneered the use of telehealth in our division, and then helped guide its sudden widespread adoption by my peers during the COVID-19 crises. Looking forward, I expect what we have learned during the pandemic will inform what we do for DBPCI 2.0.
Assistant Professor of Material Science and Engineering and, by courtesy of Pediatrics (Endocrinology)
Current Research and Scholarly Interests The underlying theme of the Appel Lab at Stanford University integrates concepts and approaches from supramolecular chemistry, natural/synthetic materials, and biology. We aim to develop supramolecular biomaterials that exploit a diverse design toolbox and take advantage of the beautiful synergism between physical properties, aesthetics, and low energy consumption typical of natural systems. Our vision is to use these materials to solve fundamental biological questions and to engineer advanced healthcare solutions.
Ronald L. Ariagno
Professor (Clinical) of Pediatrics, Emeritus
Current Research and Scholarly Interests Developmental Physiology and Sudden Infant Death Syndrome Research Laboratory closed in 2008.
Current effort, as Chair of Task Force and neonatal consult at the FDA, is to establish through consensus a culture of investigation and collaboration for all clinical neonatology practices: academic, corporate and community based to maximize the opportunity to participate in research effort needed for the regulatory approval of neonatal therapeutics to improve the outcome of critically ill infants.
Anna Chen Arroyo, MD, MPH
Clinical Assistant Professor, Medicine - Pulmonary, Allergy & Critical Care Medicine
Bio Dr. Arroyo specializes in the treatment of allergic conditions including drug allergy and asthma. She has a special interest in understanding health and healthcare disparities in allergic diseases and how allergies change over a person's lifetime.
Director, Stanford Cancer Institute, Jerome and Daisy Low Gilbert Professor and Professor of Biochemistry
Current Research and Scholarly Interests Telomeres are nucleoprotein complexes that protect chromosome ends and shorten with cell division and aging. We are interested in how telomere shortening influences cancer, stem cell function, aging and human disease. Telomerase is a reverse transcriptase that synthesizes telomere repeats and is expressed in stem cells and in cancer. We have found that telomerase also regulates stem cells and we are pursuing the function of telomerase through diverse genetic and biochemical approaches.

Lucile Salter Packard Professor of Pediatrics and Professor of Microbiology and Immunology
Current Research and Scholarly Interests Our laboratory investigates the pathogenesis of varicella zoster virus (VZV) infection, focusing on the functional roles of particular viral gene products in pathogenesis and virus-cell interactions in differentiated human cells in humans and in Scid-hu mouse models of VZV cell tropisms in vivo, and the immunobiology of VZV infections.
