Researchers at the University of Cincinnati (UC) have identified key molecular components linking circadian rhythms and cell division cycles in Neurospora crassa, providing insights that could lead to improved disease treatments and drug delivery.

The researchers in the UC College of Medicine Department of Molecular and Cellular Physiology, led by Christian Hong, PhD, published their findings Monday, Jan. 13, online ahead of print in PNAS (Proceedings of the National Academy of Sciences).

“Our work has large implications for the general understanding of the connection between the cell cycle and the circadian clock,” says Hong, an assistant professor in the molecular and cellular physiology department who collaborated with an international team of researchers on the project.

Funding for Hong’s research was provided by a four-year, $3.7 million grant from the Defense Advanced Research Projects Agency (DARPA), an agency of the U.S. Department of Defense. He also received startup funds from UC’s molecular and cellular physiology department.

The circadian rhythm, often referred to as the biological clock, is a cycle of biological activity based on a 24-hour period and generated by an internal clock synchronized to light-dark cycles and other external cues.
