p38γ/δ activation alters cardiac electrical activity and predisposes to ventricular arrhythmia - Nature Cardiovascular Research
Abstract Ventricular fibrillation (VF) is a leading immediate cause of sudden cardiac death. There is a strong association between aging and VF, although the mechanisms are unclear, limiting the availability of targeted therapeutic interventions. Here we found that the stress kinases p38γ and p38δ are activated in the ventricles of old mice and mice with genetic or drug-induced arrhythmogenic conditions.
Transcription Factor GATA4 Regulates Cell Type-Specific Splicing Through Direct Interaction With RNA in Human Induced Pluripotent Stem Cell-Derived Cardiac Progenitors | Circulation
Originally publishedhttps://doi.org/10.1161/CIRCULATIONAHA.121.057620Circulation. 2022;0:CIRCULATIONAHA.121.057620 Abstract Background: GATA4 (GATA-binding protein 4), a zinc finger–containing, DNA-binding transcription factor, is essential for normal cardiac development and homeostasis in mice and humans, and mutations in this gene have been reported in human heart defects.
