Bio The Abu-Remaileh Lab is interested in identifying novel pathways that enable cellular and organismal adaptation to metabolic stress and changes in environmental conditions. We also study how these pathways go awry in human diseases such as cancer, neurodegeneration and metabolic syndrome, in order to engineer new therapeutic modalities.
To address these questions, our lab uses a multidisciplinary approach to study the biochemical functions of the lysosome in vitro and in vivo. Lysosomes are membrane-bound compartments that degrade macromolecules and clear damaged organelles to enable cellular adaptation to various metabolic states. Lysosomal function is critical for organismal homeostasis?mutations in genes encoding lysosomal proteins cause severe human disorders known as lysosomal storage diseases, and lysosome dysfunction is implicated in age-associated diseases including cancer, neurodegeneration and metabolic syndrome.
By developing novel tools and harnessing the power of metabolomics, proteomics and functional genomics, our lab will define 1) how the lysosome communicates with other cellular compartments to fulfill the metabolic demands of the cell under various metabolic states, 2) and how its dysfunction leads to rare and common human diseases. Using insights from our research, we will engineer novel therapies to modulate the pathways that govern human disease.

Cristina M. Alvira
Associate Professor of Pediatrics (Critical Care) at the Stanford University Medical Center
Current Research and Scholarly Interests The overall objective of the Alvira Laboratory is to elucidate the mechanisms that promote postnatal lung development and repair, by focusing on three main scientific goals: (i) identification of the signaling pathways that direct the transition between the saccular and alveolar stages of lung development; (ii) exploration of the interplay between postnatal vascular and alveolar development; and (iii) determination of developmentally regulated pathways that mediate lung repair after injury.
Professor of Pediatrics (Infectious Diseases) and of Microbiology and Immunology
Current Research and Scholarly Interests My laboratory studies how bacteria colonize our bodies for long periods of time, and how interactions between bacteria and the epithelial surfaces of the gastrointestinal tract and skin may lead to disease. Epithelial surfaces are the first barrier against infection, but they also where our bodies meet and co-evolve with the microbial world.. Several of our studies have focused on the epithelial junctions as a target for bacterial pathogens. The host epithelium uses its epithelial junctions to form a tight but dynamic barrier with an external surface that is inhospitable to microbial attachment, secretes anti-microbial compounds, and has a rapid rate of self-renewal. The balance in the microbe-epithelial relationship results in silent commensalism or symbiosis; an imbalance results in diseases ranging from acute bacterial invasive disease to chronic ulcers or carcinoma.
Our laboratory has developed novel microscopy applications such as quantitative 3D confocal microscopy, electron microscopy, time-lapse imaging, microinjection and micromanipulation to visualize the interaction of pathogens with epithelial cells in culture and in animal and human tissues. Many of out studies focus on the gastric pathogen Helicobacter pylori, but we have also expanded our investigations to include the intestinal pathogens Listeria monocytogenes and Salmonella enterica, and the skin pathogen and colonizer Staphylococcus aureus. I believe that elucidating how microbes communicate with and alter our epithelial cells at a molecular level will be important for finding novel therapeutic targets to control mucosal colonization and prevent invasive disease.
Using this perspective, we have uncovered several novel concepts of how bacteria colonize and breach our epithelial surfaces. For example, we discovered that Helicobacter pylori target the intercellular junctions, and in particular that the virulence factor CagA affects junction assembly and cell polarity. This confers H. pylori the ability to extract nutrients and grow directly on the epithelial surface. We also found that these properties of CagA have consequences for cellular transformation of the epithelium. For instance, we showed that H. pylori affect the activity and state of epithelial stem cells in the stomach by colonizing the epithelial surface deep in the gastric glands. This gland-associated population is essential for pathological inflammation and hyperplasia in animal models, and confers significant colonization advantages to the bacteria. Our Listeria research uncovered a new mechanism and site where bacteria can breach the gastrointestinal epithelial barrier to invade. We found that Listeria find their receptor for invasion at sites of epithelial senescence, where the epithelial junctions undergo dynamic turnover. To study Salmonella and H. pylori we have developed a human organoid model to study their interactions with human gut epithelium in vitro. To study Staphylococcus aureus pathogenesis, we have developed methods to visualize infection at the scale of a single bacterial microcolony using an organoid culture system of human keratinocytes and fibroblasts that grow into a 3D skin-equivalent. We recently identified several proteins at the eptithelial junctions as host factors involved in the pathogenesis of one of Staphylococcus aureus major toxins.

Justin P. Annes M.D., Ph.D.

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.
Clinical Associate Professor, Pediatrics - Adolescent Medicine
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.

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.

Associate Professor (Research) of Pediatrics (Stem Cell Transplantation)
Current Research and Scholarly Interests In the coming years, I plan to further determine the genetic and immunological basis of diseases with autoimmunity or immune dysregulation in children. I believe that much can still be learned from the in depth mechanistic studies of pediatric autoimmune diseases. Genomic analysis of the patients' samples has become possible which may provide a rapid indication of altered target molecules. I plan to implement robust functional studies to define the consequences of these genetic abnormalities and bridge them to the patient's clinical phenotype.
Understanding functional consequences of gene mutations in single case/family first and then validating the molecular and cellular defects in other patients with similar phenotypes, will anticipate and complement cellular and gene therapy strategies.

Associate Professor of Genetics
Current Research and Scholarly Interests Our lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. Work in the Barna lab is presently split into two main research efforts. The first is investigating ribosome-mediated control of gene expression genome-wide in space and time during cellular differentiation and organismal development. This research is opening a new field of study in which we apply sophisticated mass spectrometry, computational biology, genomics, and developmental genetics, to characterize a ribosome code to gene expression. Our research has shown that not all of the millions of ribosomes within a cell are the same and that ribosome heterogeneity can diversify how genomes are translated into proteomes. In particular, we seek to address whether fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity or composition that are tuned to translating specific transcripts by virtue of RNA regulatory elements embedded within their 5?UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells. We apply and create bioengineering tools to manipulate such cellular interactions and signaling in-vivo.
