27078157 GPR4 induces angiogenesis via GPR4-induced p38-mediated IL6, IL8 and VEGFA secretion at acidic extracellular pH in squamous cell carcinoma of the head and neck
23888957 The results suggested that GPR4 may play an important role in the development of epithelial ovarian carcinoma (EOC), and its overexpression might be required for the angiogenesis, tumor growth, and metastasis of EOC
22110680 acidosis/GPR4 signaling regulates endothelial cell adhesion mainly through the G(s)/cAMP/Epac pathway
20211729 The mutation of histidine residue at 79, 165, or 269 from the N-terminal of GPR4 to phenylalanine shifted the half-maximal effective concentration (EC(50)) of proton-induced signaling activities to the right, including cAMP accumulation.
17462861 Previously postulated "ligand-independent" signaling of GPR4 is mediated through proton-sensing mechanisms.
17437524 lysophosphatidylcholine receptor G protein-coupled receptor 4 (GPK4) was expressed in YPEN-1 cells and triggered the cAMP/protein kinase A/cAMP response element-binding protein pathway, resulting in upregulation of adhesion molecules.
17364894 GPR4 in brain endothelial cells regulates monocyte transmigration.
16461426 GPR4 may play a critical role in the inflammatory responses activated by lysophosphatidylcholine
15857892 results identify sphingosylphosphorylcholine and its receptor, G protein-coupled receptor 4(GPR4), as critical regulators of the angiogenic potential of endothelial cells
15221007 GPR4 and TDAG8 overexpression in human tumors plays a role in driving or maintaining tumor formation
