Research Areas

Mitochondria play important roles in many cellular processes, such as modulating reactive oxygen species (ROS), energy metabolism, and apoptosis. Mitochondria also contribute significantly to the tumor development and the response of tumor cells to anticancer therapy. Mitochondria are thus emerging as promising therapeutic targets for cancer. Dr. Qian revealed that the mitochondrial genome is crucial for the effect of platinum anticancer agents; and the disruption of mitochondrial dynamics impacts genome stability, which established a novel link between the changes of mitochondrial morphology with cancer and aging. Dr. Qian’s work has led to the discovery of the important anticancer properties of mitochondrial division inhibitors (a novel class of thioxodihydroquinazolinone small molecules), including the tumor cell-specific antimitotic effect through inducing acentrosomal mitotic spindles (acentrosomal spindle inducers, ASI), and the synergistic effect with platinum-based chemotherapeutic drugs in drug resistant tumors through activating Bax/Bak-independent mitochondrial apoptosis. Platinum drug resistance is directly related with cancer treatment failure and shorter survival for many types of cancers. Dr. Qian’s current research interests focus on the development of mitochondrial-targeted ROS-based novel anticancer therapeutic strategies, understanding the role of mitochondrial genome in cellular genome stability, and the preclinical development and mechanism studies of thioxodihydroquinazolinone small molecules in drug resistant cancers.
