David Q. Matus, PhD

Hallmarks of cancer progression are increases in both uncontrolled proliferation and invasive behavior, leading to the spread of tumor cells throughout the body. This collaborative project is founded upon an experimental observation made by Dr. Matus, in the model roundworm, C. elegans, that cell invasion and cell division are mutually exclusive behaviors. In other words, a cell cannot simultaneously invade and divide. This functional link between cell cycle arrest and invasive behavior has not been directly made before, although in a variety of cancers there is correlative data suggesting that tumor cells become less proliferative during invasion. Cell invasive behavior occurs during normal embryonic development, immune surveillance, and is dysregulated during metastatic cancer progression. As two cell and developmental biologists, Dr. Matus and Dr. Martin, will leverage their expertise in the strengths of two model systems, C. elegans and the zebrafish, D. rerio, to identify how regulation of the cell cycle intersects with acquisition of cell invasive behavior. Together, they will examine and manipulate the cell cycle state of human cancer cells during metastasis, visualizing invasive behavior at high resolution using light sheet microscopy. Insights from their work will have profound implications in future design of therapeutics to eradicate invasive cells that may escape traditional chemotherapeutic agents that only target actively dividing cells.
