Cancer researchers receive Damon Runyon Innovation Award

Hallmarks of cancer progression are uncontrolled proliferation (division) of cancer cells and invasive behavior, leading to the spread of tumor cells throughout the body. Now two Stony Brook University cell biologists, David Matus, PhD, and Benjamin Martin, PhD, have discovered that cell division and invasion are mutually exclusive behaviors.

For this novel finding, the Damon Runyon Cancer Research Foundation has awarded the researchers with the 2017 Damon Runyon-Rachleff Innovation Award and a two-year grant of $300,000, followed by another renewable grant of $300,000 for an additional two years to further advance their work.

“Cells can’t divide and invade at the same time, and most cancer drugs attack tumor overproliferation,” said Dr. Matus, an Assistant Professor in the Department of Biochemistry and Cell Biology. “Therefore, we hope our laboratory findings become a key foundation to better understanding the metastatic process in order to design new drugs that attack cancer cells by their mutually exclusive behaviors.”

Drs. Matus and Martin, also an Assistant Professor in the Department of Biochemistry and Cell Biology, developed a joint project where they found in the model roundworm, C. elegans, that cell invasion and cell division are mutually exclusive behaviors. This functional link between cell cycle arrest and invasive behavior has not been directly made before, although in a variety of cancers there exists 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. In their ongoing research, the team 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. As the genetic machinery that regulates the cell cycle is deeply conserved across evolution, insights gained by studying invasive behavior during nematode and fish development will be directly tested in a zebrafish xenograft model. 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.

In recognizing the potential of Drs. Matus and Martin’s work, the Damon Runyon Cancer Research Foundation stated that “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.”
