Abstract
- In dilated cardiomyopathy (DCM), adverse myocardial remodeling is essential, potentially involving Notch signaling. We hypothesized that secreted Notch ligands would be dysregulated in DCM. We measured plasma levels of the canonical Delta-like Notch ligand 1 (DLL1) and non-canonical Notch ligands Delta-like 1 homologue (DLK1) and periostin (POSN) in 102 DCM patients and 32 matched controls. Myocardial mRNA and protein levels of DLL1, DLK1, and POSN were measured in 25 explanted hearts. Our main findings were: (i) Circulating levels of DLL1 and POSN were higher in patients with severe DCM and correlated with the degree of diastolic dysfunction and (ii) right ventricular tissue expressions of DLL1, DLK1, and POSN were oppositely associated with cardiac function indices, as high DLL1 and DLK1 expression corresponded to more preserved and high POSN expression to more deteriorated cardiac function. DLL1, DLK1, and POSN are dysregulated in end-stage DCM, possibly mediating different effects on cardiac function. [ABSTRACT FROM AUTHOR]
