Cardiac small heat shock proteins are required for morphogenesis of the heart tube and they interact genetically with gata4. (A) Representative cardiac phenotypes observed at 3 dpf of myl7:gfp embryos. Non-looping is defined by the failure of the ventricle to align perpendicular to the atrium. (B) Quantification of the cardiac phenotypes in wildtype embryos (wt, n=54), embryos injected with standard control MO (control, n=46), hspb7 MO (hspb7, n=67), or hspb12 MO (hspb12, n=89). (C) Quantification of the cardiac phenotypes in wildtype embryos (wt, n=20) or embryos injected with sub-threshold concentrations of MO specific for gata4 (n=38), hspb7 (n=36), or hspb12 (n=29), or with the same concentrations combined (gata4+hspb7, n=29) or (gata4+hspb12, n=49).
