    Dr. Jun Sun - May 13  

    Exploring vitamin D/vitamin D receptor and microbiota in chronic inflammation: push the envelope

    Dr. Jun Sun is a tenured Associate Professor University of Illinois at Chicago. She is a fellow of American Gastroenterological Associate. Her research interests are host-bacterial interactions in inflammation and cancer. Her key achievements include:

    • characterization of gut microbiome and vitamin D receptor in intestinal homeostasis and inflammation;
    • identification of bacteria in regulating intestinal stem cells; and 
    • identification and characterization of the Salmonella effector protein AvrA in host-bacterial interactions. 

    Dr. Sun has published over 120 scientific articles in peer-reviewed journals, including Cell Stem Cells, Nature Reviews, Gut, JBC, American Journal of Pathology, and American Journal of Physiology-GI. She is in the editorial board of more than 10 peer-reviewed international scientific journals. She services study sections for the NIH, American Cancer Society and other national and international research foundations. Her research is supported by the NIH, NY State STEM IDEAL Award, the American Cancer Society Research Scholar Award and a few other research awards.
    Using cultured models, transgenic mouse models, germ-free animals, and human samples, her lab is currently working on the following directions: 

    • novel roles of gut microbiome in colon cancer, inflammatory bowel diseases, infectious diseases, ALS, and other human diseases;
    • bacterial regulation of vitamin D receptor in inflammation and cancer; and
    • bacterial regulation of intestinal stem cells.
