Stephanie Olivier-Van Stichelen, PhD
Assistant Professor, Biochemistry
Medical College of Wisconsin
Dr. Olivier-Van Stichelen received her PhD degree in Biochemistry from the University of Lille, France in 2012. Her work was focused on the understanding of the nutrient-sensing O-GlcNAcylation in colorectal cancer development with a special interest in diet-dependent modification of the oncogene beta-catenin.
After completion of her degree, she was appointed as a post-doctoral Fellow in the Laboratory of Cellular and Molecular Biology at the National Institute of Health, Bethesda, MD, USA. In this lab, Dr. Olivier-Van Stichelen worked on different aspects of O-GlcNAcylation during development including X-inactivation of the O-GlcNAc Transferase gene. She also developed a brain O-GlcNAcase knockout model and studied the impact of sugar consumption during pregnancy on O-GlcNAc-dependent development of metabolic homeostasis. More recently, she developed interests in understanding the importance of artificial sweeteners for offspring’s metabolism and microbiome.
Dr. Olivier-Van Stichelen established her lab at the Medical College of Wisconsin at the crossroad of sweeteners, pregnancy, development and metabolism.
Due to the global trend of growing sweetener consumption, determining the interplay between diet and pre- and post-natal development is emerging as a critical area for research. Currently, the average American eats around 22 teaspoons of added sugar every day (30 sugar cubes/day hidden in foods). This modern glucose-rich diet correlates with an increase in the prevalence of obesity, diabetes and others metabolic syndromes. Moreover, the effort to reduce sugar consumption has led people to consume more non-caloric sweeteners (Aspartame, Sucralose, Acesulfame-K…). While they appear healthier for glucose homeostasis than a high carbohydrate diet, recent studies have shown that artificial sweeteners impact glucose metabolism as well as gut microbiota, rising questions about their excessive use.
Therefore, understanding what happens when caloric and non-caloric sweeteners are metabolized is of utmost importance for public health and the focus of my research group.
O-GlcNAcylation is one of the key components of diet-responsive signaling. This unique glucose rheostat is a ubiquitous and dynamic glycosylation of intracellular proteins with approximately 1000 modified proteins described to date. Two key enzymes drive O-GlcNAc cycling: The O-GlcNAc transferase (OGT) adds the modification and the O-GlcNAcase (OGA) removes it. Although many studies have focused on the decrease or complete absence of O-GlcNAc cycling by modulating the expression or activity of OGT, only a few studies have targeted hyper-O-GlcNAcylation by disturbing OGA. Because this post-translational modification is directly dependent on glucose input, depleting OGA creates an artificial and constant hyperglycemia-induced O-GlcNAcylation state. Using Oga and Ogt knockout (KO) cellular and mouse models, we can decipher the impact of high carbohydrate diet on embryonic development.
Part of my lab is interested in understanding the impact of Non-Nutritive Sweetener (NNS) consumption through pregnancy and lactation. Although, NNS have been found in mother’s milk and in placental blood circulation, no study has focused on the fundamental effect of those non-caloric sweeteners on the developing organism.
Among the impacts described in adults are changes in intestinal hormonal secretion, glucose metabolism and most fascinating, re- duction of the gut microbiota. Nevertheless, the fundamental mechanisms of those changes are far from understood. Glycoproteins found on the surface of the intestinal epithelium define the glycocalyx and are an essential mammalian mechanism of communication with the gut microbiome. Their reciprocal relationship with the gut microbiome regulates not only nutrient breakdown, and food absorption, but also infection. We are convinced that by altering both microbiome and the detoxification process, NNS exposure in early life will impact metabolic homeostasis later in life.
Xiaowen Bai, MD, PhD
Associate Professor, Cell Biology, Neurobiology & Anatomy
Medical College of Wisconsin
Dr. Bai’s research interests are centered on the application of stem cells on disease modeling and tissue regeneration. The current major focus of the laboratory is to utilize gain- and loss-of-function approaches to examine the novel molecular mechanisms underlying the roles of non-coding RNAs, mitochondria, and genetic factors in neurodegeneration and cardiotoxicity in mice, and translate the findings to humans using stem cell-derived brain cells, heart cells, three-dimensional mini brains, and heart organoids.
Non-coding RNAs, mitochondria, and cell stress-related genes in neurodegeneration:
Neurological disorders have emerged as a predominant healthcare concern in recent years due to their severe consequences on quality of life and prevalence throughout the world. Understanding the underlying mechanisms of these diseases and the interactions between different brain cell types is essential for the development of new therapeutics. Many drugs (e.g., anesthetics), environmental factors (e.g., alcohol), diseases, and genetic risks are related to neurodegeneration. We examine the novel molecular mechanisms underlying the roles of microRNAs, long non-coding RNAs, mitochondria, immediate early and other cell stress-related genes in neurodegeneration using both mouse, and human stem cell-derived brain cell and three-dimensional mini brain models
Stem cell-mediated myocardial regeneration
Myocardial infarction is one of the major causes of death throughout the world. Currently, there is not a highly effective approach for treatment. Stem cells hold promise in repairing injured cardiac tissue. Our lab is involved in studying the effect of the transplantation of adipose tissue-derived stem cells and induced pluripotent stem cell-derived cardiomyocytes on myocardial regeneration following ischemia injury. A molecular imaging method has been developed to investigate the molecular mechanisms controlling homing, engraftment, and survival of injected cells in vivo.
The mechanisms of impaired cardioprotection under diabetic conditions
Hyperglycemia has been shown to be particularly detrimental to the cardioprotective effects, with the underlying mechanisms remaining largely unknown. We have developed and validated a clinically relevant model of functional human cardiomyocytes derived from both normal induced pluripotent stem cells (iPSCs) and diabetes mellitus iPSCs. This in vitro model of human disease will enable developmental and comparative studies of normal and diabetic cardiomyocytes to address genetic and environmental mechanisms responsible for attenuation of cardioprotection signaling in diabetics.
