TRPV1 28 μM (EC50) |
GSK205 (100 μM) potently antagonizes TRPV4 in 3T3-F442A adipocytes, as it effectively blocks the calcium influx caused by TRPV4 agonist[1].
GSK205 (5 μM; 4 days; T3-F442A adipocytes) treatment results in increases expression of thermogenic genes (Mcp1, Mip1α, Mcp3, Rantes and Vcam, et al.) and is also accompanied by a decrease in the proinflammatory gene program. This shift resembles the gene expression changes seen in TRPV4-deficient adipocytes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
