EGFR inhibition leads to enhanced desmosome assembly and cardiomyocyte cohesion via ROCK activation.

Arrhythmogenic cardiomyopathy (AC) is a familial heart disease partly caused by impaired desmosome turnover. Thus, stabilization of desmosome integrity may provide new treatment options. Desmosomes, apart from cellular cohesion, provide the structural framework of a signaling hub.
