| Bioactivity | Luspatercept (ACE-536) is a recombinant modified ActRIIB fusion protein that binds with transforming growth factor β superfamily ligands. Luspatercept increases the erythrocyte numbers and promotes maturation of erythroid precursors. Luspatercept binds with GDF11 and inhibits Smad2/3 signaling. Luspatercept can be used for the research of anemia[1]. |
| Invitro | Luspatercept (0.1-1000 ng/mL) 抑制 A204 细胞中 GDF11 和 GDF8 诱导的 Smad2 和 Smad 3 信号通路[1]。Luspatcept 与 GDF11，GDF8，activin B，BMP10 和 BMP6 结合[1]。 |
| In Vivo | Luspatercept (0.1-60mg /kg，皮下注射；10mg /kg，静脉注射；每周 2 次，共 8 周) 增加小鼠、大鼠和猴子的红细胞 (RBC) 数量、血红蛋白水平和红细胞堆积[1]。Luspatercept (10mg /kg，皮下注射，1 次) 降低 C57BL/6 小鼠骨髓和脾脏中的红细胞形成单位 (BFU-Es) 和红血球形成单位 (CFU-Es)[1]。Luspatercept (10mg /kg，腹腔注射，1 次) 抑制小鼠脾脏 Smad2/3 磷酸化[1]。 Animal Model: |
