Greenberg Lab Publication Highlighted in Circulation

A recent publication in PNAS (Clippinger et al.) from the Greenberg lab was highlighted in Circulation. The Greenberg lab demonstrated how a mutation that causes genetic heart failure affects not only how the proteins in the heart generate force, but also how heart cells respond to changes in their mechanical environment. This work has important implications for the development of new precision medicine therapies for heart failure.
