Robo4 maintains the barrier function of the mature vascular network by inhibiting endothelial permeability induced by pro-angiogenic factor and the function of Robo4 was tissue specific. The aim of this study was to investigate the role and signaling pathways of Robo4 in pulmonary endothelial permeability in Lipopolysaccharides (LPS) induced acute lung injury (ALI) in mice. Mice were challenged by intra-peritoneal (IP) injection of LPS (15 mg/kg) 48 h after gene transfer of Retro-hRobo4. Protein in bronchoalveolar lavage fluid (BALF), lung wet/dry ratio, lung injury score, MPO activity, secondary cytokine and survival rate was recorded. Co-immunoprecipitation (Co-ip) was used to detect the binding of Robo4 and RhoA. Robo4 mRNA and protein concentration in mice lungs were significantly increased after retrovirus-mediated gene delivery. Up-regulation of Robo4 significantly decreased pro.. View More»
