In the present study, we sought to elucidate whether Cornin contributes to induce angiogenesis and its mechanisms. To this end, we examined the role of Cornin on human brain microvascular endothelial cell line (HBMEC) proliferation, invasion, and tube formation in in vitro. For study of mechanism, the phosphoinositide 3 kinase (PI3K)-Akt inhibitor LY294002, endothelial nitric oxide synthase (eNOS) inhibitor L-NAME, vascular endothelial growth factor (VEGF) antagonist sFlt-1 and VEGF receptor blocker SU-1498 were used. HMBEC proliferation was tested by MTT. Scratch adhesion test was used to assess the ability of invasion. A matrigel tube formation assay was performed to test capillary tube formation ability. PI3K-Akt-eNOS-VEGF pathway activation in HMBEC was tested by Western blot. Our data suggested that Cornin induces angiogenesis in vitro by increasing proliferation, invasion and tube formation. VEGF expression was increasing by Cornin and counteracted by VEGF antagonist sFlt-1, LY294002 and L-NAME in HMBEC. Tube formation was increased by Cornin and counteracted by VEGF receptor blocker-SU1498, LY294002 and L-NAME. It may be suggested that Cornin induces angiogenesis in vitro via a programmed PI3K/Akt/eNOS/VEGF signaling axis.

In this study, we sought to elucidate whether protocatechuic acid contributes to induce angiogenesis as well as its mechanisms. To this end, we examined the role of protocatechuic acid on human brain microvascular endothelial cell line (HBMEC) proliferation, invasion and tube formation in in vitro. For the study of mechanisms involved, the phosphoinositide 3 kinase (PI3K)-Akt inhibitor LY294002, the endothelial nitric oxide synthase (eNOS) inhibitor L-NAME, vascular endothelial growth factor (VEGF), antagonist sFlt-1 and VEGF receptor blocker SU-1498 were used. Proliferation of HBMEC was tested by MTT. Scratch adhesion test was used to assess the ability of invasion. A Matrigel tube formation assay was performed to test capillary tube formation ability. PI3K-Akt-eNOS-VEGF pathway activation in HBMEC was tested by Western blot. Our data suggested that protocatechuic acid induces angiogenesis in vitro by increasing proliferation, invasion and tube formation. VEGF expression was increasing by protocatechuic acid and counteracted by VEGF antagonist sFlt-1, LY294002 and L-NAME in HBMEC. Tube formation was increased by protocatechuic acid and counteracted by VEGF receptor blocker-SU1498, LY294002 and L-NAME. These data suggest that protocatechuic acid may be a candidate therapy for stroke recovery by promoting angiogenesis via a programmed PI3K/Akt/eNOS/VEGF signalling axis.
