Patritumab
Based on 2 publication(s) in Google Scholar
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.

ERBB3/HER3
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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:DiFi-HRG cells
-
Concentration:10 μg/mL
-
Incubation Time:6 hours
-
Result:Inhibited the phosphorylation of HER3 and AKT as well as down-regulated survivin expression.
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].

-
Animal Model:Female athymic nude mice (BALB/c; 5-6 weeks old) with DiFi-Mock1 or DiFi-HRG4 (s.c.)[1]
-
Dosage:1 mg/body
-
Administration:Intraperitoneal injection; twice a week for 4 weeks
-
Result:Individual Patritumab treatment had little effect on the growth of tumors formed by either cell line.
Combination of Cetuximab and Patritumab induced substantial regression of DiFi-HRG4 xenografts.

Flow cytometric analysis of 1×106 MCF-7 cells labelling HER3 (red) with Patritumab (HY-P99275). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1(K214R) kappa Isotype Control (HY-P99995, blue) was used as the isotype control. -
Immobilized Human HER3/ERBB3 Protein (ECD, His Tag) can bind Patritumab. The EC50 for this effect is 1.41 ng/mL. -
Loaded Patritumab on AHC2 biosensor, can bind HER3 Protein, Human (HEK293, His, HY-P72625) with an affinity constant of 1.804E-09 M as determined in BLI assay.
