Protein dynamics in the beating heart

The protein titin is a large structural component of the sarcomere—the machinery that mediates contraction of cardiac muscle cells. Despite its importance to the beating heart, little is known about titin turnover. Adrian Cadar, Ph.D., and colleagues have now used the microscopy technique FRAP (fluorescence recovery after photobleaching) to study titin dynamics in contracting cardiomyocytes. […]

Study of tick-borne disease dynamics could thwart future outbreaks

The Centers for Disease Control and Prevention (CDC) released a report earlier this year on the increase of tick-, flea- and mosquito-borne illnesses in the United States, but don’t panic. Kurt Vandegrift, assistant research professor of biology at Penn State, works on emerging infectious diseases, and his lab studies ticks. Vandegrift’s lab is part of a National […]
