体外研究(In Vitro)
Demcizumab (0-100 μg/mL) 结合人 DLL4 但不结合鼠 DLL4,并在 FACS 结合测定中阻断 DLL4 与 Notch1 受体的结合。Demcizumab (20 μg/mL,48 小时) 降低 PDTALL 细胞中的 HES1 和 DTX1 mRNA 表达。Demcizumab (0-80 μg/mL,1 或 2 或 3 天) 促进 PDTALL13 细胞死亡和早期凋亡。 has not independently confirmed the accuracy of these methods.

体内研究(In Vivo)
Demcizumab (10 mg/kg,i.p.,每周一次) 联合 Irinotecan (7.5 mg/kg) 在 KRAS 和 KRAS CRC 异种移植模型中显示出显着的抗肿瘤作用.
Demcizumab 单独或与伊立替康 (7.5 mg/kg) 联合使用对 OMP-C8 结肠肿瘤有效。
Demcizumab (20 mg/kg/周,腹腔注射) 增加注射了 PDTALL13 细胞的受辐照 NRG 小鼠的存活率。 has not independently confirmed the accuracy of these methods. They are for reference only.
