BMS453 (BMS-189453) 是一种合成类维生素 A,是一种RARβ激动剂和RARα/RARγ拮抗剂。BMS453 主要通过诱导活性 TGFβ 来抑制乳腺细胞生长。
生物活性 | BMS453 (BMS-189453), a synthetic retinoid, is aRARβagonist and aRARα/RARγantagonist. BMS453 inhibits breast cell growth predominantly through the induction of active TGFβ[1][2]. |
体外研究 (In Vitro) | BMS453 (1 μM; 11 hours; 184 and HMEC cells) treatment inhibits the proliferation of normal breast cell growth without significantly inducing apoptosis[2]. BMS453 (1 μM; 5 days; 184 and HMEC cells) treatment inhibits normal breast cell proliferation by causing G1 arrest[2]. BMS453 (1 μM; 24-72 hours; 184 cells) treatment induces Rb hypophosphorylation and decrease CDK2 kinase activity. BMS453 increases total p21 protein levels and CDK2-bound p21 protein, but does not change CDK4-bound p21[2]. BMS453 inhibits breast cell growth predominantly through the induction of active TGFβ[2].
Cell Proliferation Assay[2] Cell Line: | Normal human mammary epithelial cells (184 and HMEC) | Concentration: | 1 μM | Incubation Time: | 11 hours | Result: | Inhibited3H-thymidine uptake in normal breast cells (184 and HMEC) by 40 %. |
Cell Cycle Analysis[2] Cell Line: | Normal human mammary epithelial cells (184 and HMEC) | Concentration: | 1 μM | Incubation Time: | 5 days | Result: | Increased the proportion of cells in G0/G1 phase and decreased the proportion of cells in S phase. |
Western Blot Analysis[2] Cell Line: | 184 cells | Concentration: | 1 μM | Incubation Time: | 24 hours, 48 hours, 72 hours | Result: | Induced Rb hypophosphorylation and decrease CDK2 kinase activity. |
