Conditional Cardiac-Specific Akap13 Knockout Induces Sex Dependent Biventricular Dilated Cardiomyopathy With Sarcomeric And Mitochondrial Defects, Kimberlyn M. Baig-Ward

Theses and Dissertations

Heart disease is a complex and heterogeneous disease. Notably, studies have demonstrated gender differences in the expression and types of cardiovascular disease, such as dilated cardiomyopathy (DCM), a major underlying cause of heart failure. Previously we showed that loss of A-Kinase Anchoring Protein 13 (Akap13), a unique proto-oncogene and estrogen receptor modulator, resulted in enlarged embryonic hearts, defective cardiac sarcomere formation, and embryonic lethality in mice. Data have also shown cAMP-dependent Protein Kinase A (PKA) to be involved in DCM pathophysiology. Given the established role of AKAP13 in cell signaling, its ability to bind and modulate ligand-activated nuclear hormone …
