Activation of GPR30 with G1 inhibits oscillatory shear stress-induced adhesion of THP-1 monocytes to HAECs by increasing KLF2

Agonism of GPR30 using its specific agonist G1 suppressed oscillatory shear stress (OSS)-induced expression and secretion of pro-inflammatory cytokines IL-6, IL-1β, and MCP-1 in human aortic endothelial cells (HAECs). HAECs were exposed with OSS (5 dyn/cm2) in the presence or absence of 5, 10 μM G1 for 24 h. (A). Expression of IL-6, IL-1β, and MCP-1 at the mRNA level was determined by real time PCR analysis; (B). Secretion of IL-6, IL-1β, and MCP-1 at the protein level was determined by ELISA (*, #, $, P
