In Vitro	TEI-9647 (100 nM; 24 hours; HL-60 cells) treatment clearly suppresses p21WAF1,CIP1 gene expression induced by 1α,25(OH)2D3[1]. TEI-9647 blocks both 1α,25(OH)2D3-mediated HL-60 cell differentiation and also activation of the luciferase reporter in COS-7 cells that has been transfected with the cDNA containing the DRE of the rat 25(OH)D3-24-hydroxylase gene and cDNA of the human vitamin D nuclear receptor[1]. RT-PCR[1] Cell Line: HL-60 cells Concentration: 100 nM Incubation Time: 24 hours Result: Clearly suppressed p21WAF1,CIP1 gene expression induced by 1α,25(OH)2D3.
