MedChemExpress - Model Patritumab -1262787-83-6

Patritumab (Human Anti-ERBB3 Recombinant Antibody) is a neutralizing monoclonal antibody to ERBB3. Patritumab shows a synergy with Cetuximab (HY-P9905), potently inhibits the phosphorylation of EGFR, HER2, HER3, ERK, and AKT. Patritumab also induces cell apoptosis and suppresses the growth of pancreatic, non-small cell lung cancer, and colorectal cancer xenograft tumors[1].

Description：Patritumab (Human Anti-ERBB3 Recombinant Antibody) is a neutralizing monoclonal antibody to ERBB3. Patritumab shows a synergy with Cetuximab (HY-P9905), potently inhibits the phosphorylation of EGFR, HER2, HER3, ERK, and AKT. Patritumab also induces cell apoptosis and suppresses the growth of pancreatic, non-small cell lung cancer, and colorectal cancer xenograft tumors.

In Vitro：Patritumab targets to the extracellular domain (ECD) of HER3 and (10 μg/mL; 5 d) induces DiFi-HRG4 cells apoptosis[1]. Patritumab (10 μg/mL; 6 h) markedly inhibits the phosphorylation of HER3 and AKT, without affecting that of ERK, in DiFi-HRG4 cells[1]. Patritumab (10 μg/mL; 48 h) also induces the cleavage of PARP accompanied with both up-regulation of BIM and down-regulation of survivin expression[1].

In Vivo：Patritumab (1 mg/mouse; i.p.; twice a week for 4 weeks) combines with 1 mg Cetuximab and restores Cetuximab sensitivity in DiFi-HRG tumor xenografts model in mice[1]. Heregulin produced by colorectal cancer tumors harboring wild-type KRAS induces Cetuximab resistance, and that combination therapy with cetuximab and patritumab overcomes such resistance in vivo[1].
