gstk1 knockout decreases the cardiac end diastolic and systolic volumes in zebrafish. (A) In vivo imaging of the hearts of control and gstk1-knockout (KO) Tg (myl7:mRFP) zebrafish at 5 dpf. Zebrafish were placed on slides on their backs, and the heart was imaged under a fluorescence microscope at 100 frames/s for 10 s. Image stack projections and the M-mode imaging of ventricles are shown. Bar, 100 μm. (B) Quantitative analysis of the in vivo imaging of zebrafish heart. The end diastolic volume (EDV) of gstk1-KO zebrafish was significantly smaller than that of control zebrafish, whereas the end systolic volume (ESV) and ejection fraction (EF) were not significantly different. N = 13 and 7 for the control and gstk1-KO groups, respectively. *p < 0.05, ***p < 0.001 vs. control group.
