体外研究 (In Vitro) | Xentuzumab (0.01-1 mM; 96 h) inhibits IGF type 1 receptor signaling and (0.1 μM; 48 h) AKT serine/threonine kinase (AKT) phosphorylation in VCaP, DuCaP, and MDA PCa 2b cell in a dose-dependent manner[1]. Xentuzumab (0.01-1 mM; 5-10 d) losses of antiproliferative activity against PTEN-null LNCaP or PC-3 cells when PTEN knockdown[1]. Xentuzumab (1 μM; 24-72 h) arrests cell cycle at sub-G1 phase and induces apoptosis in VCaP cells[1].
Western Blot Analysis[1] Cell Line: | Prostate cancer VCaP cells | Concentration: | 0.1 μM | Incubation Time: | 24 h and 48 h | Result: | Increased in cleaved caspase 3/7 and PARP. Decreased the level of phosphorylation of FoxO3a (S253)/FoxO1 (T24). |
Cell Cycle Analysis[1] Cell Line: | Prostate cancer VCaP cells | Concentration: | 1 μM | Incubation Time: | 24 h, 48 h, and 72 h | Result: | Increased in cleaved caspase 3/7 and induces cell apoptosis. Increased the sub-G1 cell population. |
|
体内研究 (In Vivo) | Xentuzumab (200 mg/kg i.p., once weekly for 10 weeks) in inhibits tumor growth in LuCaP 96CR patient-derived xenograft model in mice[1].
Animal Model: | Fox Chase CB17 severe combined immunodeficiency (SCID; CB17/lcr-Prkdc scid/lcrlcoCrl) male mice with LuCaP 96CR cell (s.c.)[1] | Dosage: | 200 mg/kg | Administration: | Intraperitoneal injection; once weekly for 10 weeks; sacrificed 6 hours after the last dose | Result: | Resulted in significant reductions in tumor volume. |
