Effect of angiogenic factors on Cx43.

Angiogenic factorsConnexin typeComment

VEGF [52]Cx43 GJICActivation of VEGFR2 by VEGF-E alone inhibited GJIC
VEGF [48]Cx43 GJICEGF promoted GJIC in glioblastoma multiforme cells
VEGF [48]Cx43 GJVEGF increased the expression of gap junction proteins in U-251 glioblastoma multiforme cells
VEGF [39]Cx43VEGF enhanced the expression of Cx43 in endothelial progenitor cells
VEGF [51]Cx43 GJExposure of primary porcine pulmonary artery endothelial cells to VEGF markedly suppressed Cx43 GJs within 1 hour
VEGF [52]Cx43 GJVEGF induced Cx43 phosphorylation leading to a decline in pregnancy-adapted Ca2+ burst function
VEGF [49]Cx43VEGF120 increased expression of Cx43 in heart
VEGF [50]Cx43 GJICVEGF improved intercellular communication at the Cx43 gap junction
VEGF [54]Cx43 GJICIn coronary capillary endothelium, VEGF disrupted intercellular communication and promoted Cx43 endocytosis and phosphorylation at the Cx43 gap junction
VEGF [53]Cx43 GJICVEGF induced phosphorylation of connexin 43 to regulate gap junction intercellular communication in HUVECs
VEGF [55]Cx43 GJICVEGF reversibly inhibited GJIC function in EA.hy926 cells and HUVECs
bFGF and LPS [57]Cx43 GJ and HCInhibited Cx43 gap junctions but stimulated hemichannels in C6 glioma cells
bFGF and LPS [57]Cx43 GJ and HCInhibited Cx43 hemichannels function in HeLa cells.
bFGF and VEGF [58]Cx43 GJICActed as angiogenic factors to increase gap junction heterocellular communication between endothelial cells and hematologic malignant cells
bFGF [59]Cx43 expression and GJICbFGF stimulated GJIC and promoted Cx43 expression in skin fibroblasts
bFGF [60]Cx43 expression and GJICbFGF stimulation increased Cx43 expression and GJIC in cortical progenitor cells
bFGF [61]Cx43 expression and GJICbFGF stimulation increased Cx43 expression and GJIC in cardiac fibroblasts
TNF-α [62]Cx43 HCUnder high glucose conditions, TNF-α increased Cx43 hemichannel function in EA.hy926 cells
TNF-α [63]Cx43 GJ and GJICTNF-α decreased the amount of Cx43 gap junction protein and GJIC in corneal fibroblasts
TNF-α [64]Cx43 GJICTNF-α decreased Cx43 GJIC in ovine uterine artery endothelial cells and HUVECs
MMP9 [65]Cx43The hypoxia-induced downregulation of Cx43 protein was markedly attenuated by doxycycline, an inhibitor of MMP
