The cell adhesion proteins in the AV cardiomyocytes of rhoua morpholino knockdown zebrafish hearts are mis-localized. Confocal imaging of Tg(cmlc2:ras-eGFP) control and rhoua ATG MO1 knockdown zebrafish hearts that were examined by (A, B) Alcama antibody and (C, D) N-Cadherin antibody at 60 hpf reveals mislocalization of Alcama and N-cadherin in rhoua MO1 knockdown zebrafish AV cardiomyocytes. (A-D) Tg(cmlc2:ras-eGFP)s883 AV cardiomyocytes, (A′-D′) Immunohistochemical staining of AV cardiomyocytes, (A′′-D′′) Merge of Tg(cmlc2:ras-eGFP)s883 and immunohistochemical staining analysis, (A′′′-D′′′) Boxed area of A′′-D′′, and (A′′′′-D′′′′) Schematic representation of A′′′-D′′′. White arrowhead - AV cardiomyocytes, yellow arrows - mislocalized Alcama and N-cadherin immunostaining. At - atrium, V - ventricle, Ap - apical, Ba - basal. White scale bar - 10 µM.
