Xiaodong Sun, PhD

Instructor of Hematology and Medical Oncology
Emory School of Medicine

Dr. Xiaodong Sun obtained his PhD degree from Peking Union Medical College/Chinese Academy of Medical Sciences, Beijing, China, in 2001. After receiving his postdoctoral training in the University of Virginia and Emory University, in 2007, Dr. Sun became a faculty member of the Department of Hematology and Medical Oncology, Emory University School of Medicine.

Research Interests

The goal of Dr. Sun’s research is to characterize genetic alterations and molecular function of tumor suppressor genes in human cancers. His current research is focusing on a transcription factor called ATBF1/ZFHX3 (AT-motif binding protein 1 / Zinc-finger hemeobox 3). The ATBF1 gene was identified to be involved in neuronal differentiation. Dr. Sun’s research has suggested that ATBF1 is a candidate tumor suppressor gene which is altered in several types of human malignancies. Currently, Dr. Sun is studying 1) the tumor suppressor function of ATBF1 in mouse models, particularly in the prostate and the oral cavity; 2) the signaling pathways regulated by ATBF1; 3) the mechanisms by which ATBF1 loses its function in cancer cells. In summary, Dr. Sun’s research focuses on the molecular genetics and biology of human cancers.
