rom the nucleus. The reduction in nuclear HDAC5 favored MEF2 transcription and the onset of cardiac hypertrophy."

These studies reveal a role for AKAP-Lbc in which increased expression of the anchoring protein selectively amplifies a signaling pathway that drives cardiac muscle cells to a pathophysiological outcome. "It will be important to explore the role of the AKAP-Lbc/PKD/HDAC5 signaling pathway in whole animal models to establish whether AKAP-Lbc is a valid biomarker for hypertrophic cardiomyopathy and to determine which genes are initiated upon up-regulation of the anchoring protein," offers Dr. Scott.
