Cardiac morphogenesis defects in zebrafish embryos overexpressing DN-Ldb1. (A) Confocal images of control and FLAG-HA-DN-Ldb1 mRNA injected zebrafish embryos, stained with anti-FLAG antibody at 20 somites. (B) Control or DNLdb1 mRNA injected Tg(myl7:EGFP-HsHRAS)s883 embryos at 48 hpf. Lateral view, anterior to the left. (C-D) Percentage of embryos with cardiac arrhythmia (C) and analysis of the number of heart beats per minute (D) measured at 24, 48 and 72 hpf in control and DN-Ldb1 overexpressing zebrafish embryos. (E) Confocal images of control, DN-Ldb1 overexpressing and Isl1 mutant Tg(myl7:EGFP-HsHRAS)s883 hearts, showing shortening of the atrium (dotted lines) in DN-Ldb1 overexpressing and isl1 mutant embryos.
