In 2015, the historic Paris Agreement, signed by 195 countries, sought to limit global warming to 2 °C. Ten years later, the results have yet to materialize, raising questions regarding the effectiveness of COP meetings, major climate gatherings whose thirtieth edition kicks off Monday in Brazil.

We uncover that the caudal splanchnic mesoderm (in green) acts as a midline anchor of the heart tube. In Vangl2 and Shroom3 mutants, its bilateral symmetry is disrupted, leading to a rotation of the heart tube and ventricle malposition.

New publication :
Despite being a core member of the PCP pathway, Vangl2 can play roles unrelated to planar polarity. This is the case during mouse heart morphogenesis.
