简介
Rationale
Cancer therapy can be associated with short- and long-term cardiac dysfunction. Patients with cancer often exhibit therapy-related clonal hematopoiesis (t-CH), an aggressive form of clonal hematopoiesis that can result from somatic mutations in genes encoding regulators of the DNA-damage response (DDR) pathway. Gain-of-function mutations in exon 6 of the protein phosphatase Mg2+/Mn2+ dependent 1D (PPM1D) gene are the most frequently mutated DNA-damage response gene associated with t-CH. Whether t-CH can contribute to cardiac dysfunction is unknown.
Objective
We evaluated the causal and mechanistic relationships between Ppm1d-mediated t-CH and nonischemic heart failure in an experimental system.
Methods and Results
To test whether gain-of-function hematopoietic cell mutations in Ppm1d can increase susceptibility to cardiac stress, we evaluated cardiac dysfunction in a …
