Telisotuzumab (ABT-700) is a human recombinant bivalent antibody, a therapeutic antibody against the hepatocyte growth factor receptor (MET) that binds c-Met with high affinity and inhibits c-Met signaling. Telisotuzumab has antitumor activity[1].
Telisotuzumab (ABT-700) (10 μg/mL, 24 h) 可以抑制 SNU5 细胞的增殖，并导致促凋亡的 Bim 增加和抗凋亡的 Bcl-xL 减少，从而诱发细胞凋亡[1]。
Telisotuzumab (ABT-700) (i.p., 2.5-40 mg/kg, twice a week, 90 days) 有效拮抗构成性激活的 c-Met 和下游信号，从而抑制 Hs746T 细胞 SCID 小鼠的肿瘤生长[1]。
| Animal Model: | SCID mice with Hs746T cells[1] |
| Dosage: | 2.5-40 mg/kg |
| Administration: | i.p., twice a week, 90 days |
| Result: | Reduced total and phosphorylated c-Met as well as phosphorylated Akt and Erk. Complete tumor regression at doses above 10 mg/kg but no effective inhibition of tumor growth at doses below 5mg/kg. |
