Project description:Cardiac hypertrophy is an adaptive response to pressure overload aimed at maintaining cardiac function. However, prolonged hypertrophy significantly increases the risk of maladaptive cardiac remodeling and heart failure. The role of cardiac long non-coding RNAs in cardiac hypertrophy and cardiomyopathy is not well understood. lincRNA-p21 was induced in mouse and human cardiomyopathy tissue. Global and cardiac-specific lincRNA-p21 knockout significantly suppressed pressure overload-induced ventricular wall thickening, stress marker elevation, and deterioration of cardiac function. Genome-wide transcriptome analysis and transcriptional network analysis revealed that lincRNA-p21 acts in trans to stimulate the NFAT/MEF2 pathway. Mechanistically, lincRNA-p21 bound to the scaffold protein KAP1. lincRNA-p21 cardiac-specific knockout suppressed stress-induced nuclear accumulation of KAP1, and KAP1 knockdown attenuated cardiac hypertrophy and NFAT activation. KAP1 positively regulated pathological hypertrophy by physically interacting with NFATC4 to promote the overactive status of NFAT/MEF2 signaling. Importantly, GapmeR ASO depletion of lincRNA-p21 similarly inhibited cardiac hypertrophy and adverse remodeling, highlighting the therapeutic potential of inhibiting lincRNA-p21.

Project description:Background: BMPER, an orthologue of Drosophila melanogaster crossveinless-2, is a secreted factor that regulates BMP activity in endothelial cell precursors and during early cardiomyocyte differentiation. Although previously described in the heart, the role of Bmper in cardiac development and function remained unknown. Methods: BMPER deficient hearts were phenotyped histologically and functionally using echocardiography and Doppler analysis. Since BMPER -/- mice die perinatally, BMPER +/- mice were then challenged to pressure overload induced cardiac hypertrophy and hind limb ischemia to determine changes in angiogensis and regulation of cardiomyocyte size. Results: We identified for the first time the cardiac phenotype associated with BMPER haploinsufficiency. BMPER mRNA and protein are present in the heart during cardiac development through at least E14.5 but is lost by E18.5. BMPER +/- ventricles are thinner and less compact than sibling wild-type hearts. In the adult, BMPER +/- hearts present with decreased anterior and posterior wall thickness, decreased cardiomyocyte size, and an increase in cardiac vessel density. Despite these changes, BMPER +/- mice respond to pressure overload-induced cardiac hypertrophy challenge largely to the same extent as wild-type mice. Conclusion: BMPER appears to play a role in regulating both vessel density and cardiac development in vivo; however, BMPER haploinsufficiency does not result in marked effects on cardiac function or adaptation to pressure overload hypertrophy. Unpaired, two-condition experiment, wild-type vs BMPER+/- adult hearts. Biological replicates: 4 per condition.
