Gdf11 regulates left-right asymmetry development through TGF-β signal.

ABSTRACT: During the embryonic developmental stage in vertebrates, internal organs are arranged along the left-right axis. Disruptions in this process can result in congenital diseases or laterality disorders. The molecular mechanisms of left-right asymmetry in vertebrate development remain largely unclear. Due to its straightforward structure, zebrafish has become a favoured model for studying early laterality events. Here, we demonstrate that growth and development factor 11 (Gdf11) is essential for left-right development via TGF-β signalling. Morphological analysis showed that gdf11 morphants and mutants displayed clear heart and liver laterality disorders in a Nodal signal-dependent manner. Additionally, we found that Kupffer's vesicle formation and ciliogenesis were impaired following gdf11 del
