This article, co-authored with Dr. Samantha Barrick, focuses on cardiac myosin, highlighting new regulatory mechanisms, its roles beyond sarcomeric contraction, its emergence as a drug target, and some outstanding questions for the field. The article can be found here.
In collaboration with the labs of Drs. Samantha Harris, Stuart Campbell, and Jonathan Kirk, the Greenberg lab published a paper on actomyosin dysfunction in diabetic heart failure. Congratulations to Dr. Samantha Barrick and our collaborators. The publication can here.
Congratulations to Dr. Sarah Clippinger Schulte for successfully defending her thesis. Dr. Schulte is the first Greenberg lab graduate student to receive their PhD.
A new publication in Immunity, including Greenberg lab contributions can be found here. This work stems from one of our long-standing collaborations with the Lavine lab. Congratulations to all of our co-authors.
New publication from the Greenberg lab is now online at the Molecular Biology of the Cell (here). This work, led by first author Dr. Samantha Barrick, examines a variant in troponin T associated with pediatric onset dilated cardiomyopathy. We show that this variant causes molecular and cellular alterations consistent with those seen in known pathogenic variants. We show that the molecular mechanism driving the early disease pathogenesis is reduced coupling between calcium binding to troponin C and thin filament activation. This in turn leads to changes in cellular contractility and sarcomeric organization.
The preprint, describing our collaborative project with the labs of Samantha Harris, Stuart Campbell, and Jonathan Kirk can be found here.

Our new publication determined the initial molecular insult driving the disease pathogenesis in a hypertrophic cardiomyopathy mutant and how the insult drives the activation of downstream adaptive pathways. This is a collaboration with Jeanne Nerbonne's lab. The paper can be found here. Congratulations to Sarah, Paige, David, Lina, Tom, Eve, and Jeanne.
