- Seeking to improve patient outcomes by improving response to existing therapies and developing new therapies.
Current research is focused on developing a novel approach to immunotherapy in breast cancer.
These studies may lead to alternative approaches to improving response to anti-PD-L1 therapies in breast cancer.
New immunotherapies targeting the programmed death-ligand 1 (PD-L1) have shown promising results in clinical trials for several cancers. However, only about 15-20 percent of breast cancer patients respond to this therapy and there is an increased risk for developing autoimmune disorders from the therapy.
PD-L1 is a protein that is produced by many cell types including cancer cells. It works to regulate immune response by binding to its companion receptor, PD-1 on T-Cells, thereby shutting down immune response. The normal functioning of this immune regulation can go awry in tumor cells, allowing tumors to escape immune surveillance and go undetected by immune cells that are capable of killing them. Therefore, it is imperative to develop better immunotherapy treatments.
To this end, Drs. Hung and Hortobagyi are exploring a novel approach to immune checkpoint therapy for the purpose of developing new PD-L1 targeted drugs, while also investigating the causes of resistance to these therapies in an effort to develop combination therapy to overcome the resistance.
Mien-Chie Hung, PhD is the Vice President for Basic Research, and Professor and Chair of the Department of Molecular and Cellular Oncology at the University of Texas MD Anderson Cancer Center and a basic scientist with a translational vision. Dr. Hung is a Program Leader for MDACC CCSG "Cell Biology and Signal Transduction" program. Since 2008, he has been Director of the Center for Biological Pathways at MDACC to coordinate biological pathway studies in cancers throughout the institution. Dr. Hung is internationally recognized for his work on signaling transduction pathways of tyrosine kinase growth factor receptors and targeted therapies for breast cancer. His group made a critical breakthrough in showing that the transmembrane tyrosine kinase receptor EGFR can translocate into the nucleus from the cell surface to stimulate cell proliferation and to induce resistance to anti-cancer therapy. This paradigm-shifting concept revolutionizes cell biology of the receptor tyrosine kinase and paves a new avenue for designing next generation of anti-cancer therapy. He has published nearly 400 peer-reviewed papers. Dr. Hung was inducted as an Academician of the Academia Sinica in Taiwan (2002) and a Member of the University of Texas Academy of Health Science Education (2006). In addition, he is a Member of the Scientific Advisory Council for Susan G. Komen and Fellow of the American Association for the Advancement of Science (2010), as well as recipient of the Presidential Award of Society of Chinese Bioscientists in America and The University of Texas MDACC LeMaistre Outstanding Achievement Award (2011).
