Radiotherapy repairs irregular rhythms in those with life-threatening heart arrhythmia. New research from Washington University School of Medicine in St. Louis suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.

Silva, Nerbonne labs investigate accessory proteins in steps toward precision medicine

CBAC Jianmin Cui leads a multi-institutional team to make this discovery. Dozens of commonly used drugs, including antibiotics, antinausea and anticancer medications, have a potential side effect of lengthening the electrical event that triggers contraction, creating an irregular heartbeat, or cardiac arrhythmia called acquired Long QT syndrome. While safe in their current dosages, some of these drugs may have a more therapeutic benefit at higher doses, but are limited by the risk of arrhythmia.

New findings show how CaM and PIP2 orchestrate large-scale molecular movement of the KCNQ1 cytoplasmic domain to facilitate channel opening

Weikai Li, associate professor of biochemistry and molecular biophysics at the School of Medicine, along with CBAC Member Michael J. Greenberg, assistant professor of biochemistry and molecular biophysics, and Michael L. Gross, professor of chemistry in Arts & Sciences, and of immunology and of medicine at the School of Medicine, received a three-year $750,000 grant from American Heart Association for their research titled “Interdisciplinary structural studies of iron homeostasis in cardiovascular health.”
