Panitumumab (anti-EGFR) is a fully human IgG2 anti-EGFR monoclonal antibody with anti-tumor activity. Panitumumab (anti-EGFR) inhibits tumor cell proliferation, survival and angiogenesis. Panitumumab (anti-EGFR) can be used in the research of cancers, such as colon cancer[1][2][4].
Panitumumab (2 nM-2 μM, 3 h) (anti-EGFR) inhibits ligand-dependent autophosphorylation in EGFR-expressing NCI-H1975 cells, NCI-H1650 cells and CHO cells[3].
Panitumumab (0-200 μg/mL, 48 h) (anti-EGFR) inhibits the proliferation of DLD-1 cells[4].
Panitumumab (80 μg/mL, 24 h) (anti-EGFR) increase beclin-1 (a marker of autophagy) levels in Caco-2 cells and DLD-1 cells[4].
Western Blot Analysis[3]
| Cell Line: | EGFR-expressing NCI-H1975 cells, NCI-H1650 cells and CHO cells |
| Concentration: | 2, 20, 200, 2000 nM |
| Incubation Time: | 3 h |
| Result: | Inhibited ligand-induced autophosphorylation of EGFR. |
Panitumumab (25, 100, or 500 μg/mouse, i.p., twice a week) (anti-EGFR) inhibits tumor growth in NCI-H1975 and NCI-H1650 xenografts, compared with control (P < 0.0003)[1].
| Animal Model: | NCI-H1975 and NCI-H1650 xenografts[3] |
| Dosage: | 25, 100, or 500 μg/mouse |
| Administration: | Intraperitoneal injection (i.p.), twice a week |
| Result: | Inhibited ligand-induced EGFR phosphorylation, tumor growth, and markers of proliferation. Decreased Ki-67 and phospho- mitogen-activated protein kinase (pMAPK) staining in both xenografts. |
