Cetuximab (C225) is a monoclonal antibody that inhibits epidermal growth factor receptor (EGFR), with a Kd of 0.201 nM for soluble EGFR by SPR. Cetuximab also exhibits a Kd of 0.147 nM for EGFR in fixed A431 cells by ELISA. Cetuximab (C225; 30 nM) time-dependently inhibits the proliferation of SCC-1, SCC-11B, SCC-38, and SCC-13Y cells after treatment for 8 d. Cetuximab (30 nM) causes G0/G1 arrest, induces apoptosis, and reduces Rb, p27, Bcl-2, and Bax expression in SCC-13Y cells. Cetuximab (30 nM) also enhances radiosensitivity and increases radiation-induced apoptosis in SCC-13Y cells. has not independently confirmed the accuracy of these methods. They are for reference only.

Cetuximab (1?mg/injection) has effect on the tumour volume but the effect is more pronounced on UT-SCC-14 xenografts. In UT-SCC-14 xenografts, Cetuximab treatment significantly reduces the expression of EGFR, pEGFR and Ki67. The MCT1 and GLUT1 expression is significantly decreased in the Cetuximab-treated groups of both cell lines but differences are more pronounced in UT-SCC-14 xenografts. has not independently confirmed the accuracy of these methods. They are for reference only.
