Loss of nono impairs cardiac morphogenesis and excitation–contraction coupling via the PI3K/Akt pathway in zebrafish
Pathogenic variants in NONO are clinically linked to congenital heart disease (CHD), but in vivo mechanisms and gene-targeted interventions remain poorly explored. Using CRISPR/Cas9 gene editing and morpholino silencing, we established knockout (KO) and knockdown (KD) zebrafish models to study nono in cardiogenesis. Ad...
