DIABETES
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. -

Katrin Chua
Professor of Medicine (Endocrinology, Gerontology and Metabolism)
Current Research and Scholarly InterestsOur lab is interested in understanding molecular processes that underlie aging and age-associated pathologies in mammals. We focus on a family of genes, the SIRTs, which regulate stress resistance and lifespan in lower organisms such as yeast, worms, and flies. In mammals, we recently uncovered a number of ways in which SIRT factors may contribute to cellular and organismal aging by regulating resistance to various forms of stress. We have now begun to characterize the molecular mechanisms by which these SIRT factors function. In particular, we are interested in how SIRT factors regulate chromatin, the molecular structure in which the DNA of mammalian genomes is packaged, and how such functions may link genome maintenance to stress resistance and aging.

Deborah Sellmeyer
Clinical Professor, Medicine - Endocrinology, Gerontology, & Metabolism
BioDr. Sellmeyer is an internationally recognized expert in Metabolic Bone Disease. She is a renowned clinician who joined the Stanford faculty in 2018 as a Professor of Medicine. She has been recognized for her clinical excellence with induction into the Miller Coulson Academy of Clinical Excellence while she was at Johns Hopkins. In addition to her clinical expertise, Dr. Sellmeyer maintains a research program that centers on the effect of nutrition and environmental factors on skeletal metabolism which she has investigated through both smaller CRC-based trials and large multi-center trials. Studies she has conducted have investigated the role of dietary sodium chloride, source of dietary protein (animal, vegetable, dairy, soy), role of dietary potassium and alkaline potassium salts, targeted thoracic exercises on kyphosis, whether structured exercise can prevent bone loss in premenopausal women treated for breast cancer, and studies validating nutritional assessment questionnaires. Her expertise as a clinical researcher has enabled development of a multi-disciplinary translational research team including basic scientists in the orthopedic department, junior faculty members with K grant funding, and basic scientists in the endocrine division to develop translational projects studying the effects of osteoporosis medications on basic elements of skeletal biology utilizing bone biopsies from treated individuals as well as clinical trials of novel therapies for rare bone disorders.

Aimee D. Shu
Clinical Associate Professor, Medicine - Endocrinology, Gerontology, & Metabolism
BioI am an endocrinologist with particular interests in reproductive and bone health.
I enjoy treating patients with menstrual disorders, menopause, fractures, osteoporosis, parathyroid imbalance, and calcium imbalance.
As a certified menopause practitioner (North American Menopause Society), I help women fine-tune their health at the mid-life transition. Some women transition through menopause with ease, while others experience challenging symptoms like hot flashes, slowed metabolism, and mood changes. This transition period provides a good opportunity to create a "game plan" for preserving future health. It also marks the beginning of natural bone loss, leaving one more susceptible to fragility fractures.
I provide individualized treatment plans for bone health to men and women of all ages, including for those with specific challenges such as chronic steroid use. As a certified clinical densitometrist (International Society for Clinical Densitometry), I personally review all my patients' bone density scan images. Thus, please bring any non-Stanford bone density scan images to your appointment with me.
Appointments with me are available on Stanford's main campus (300 Pastuer Drive) and at the Stanford Medicine Outpatient Center (450 Broadway, Redwood City). -
