Analysis of gene expression of cancer cell lines exposed to erlotinib, a small molecule inhibitor of the epidermal growth factor receptor (EGFR), showed a marked increase in EGFR mRNA in resistant cell lines but not in susceptible ones. Because cetuximab induces EGFR down-regulation, we explored the hypothesis that treatment with cetuximab would interfere with erlotinib-induced EGFR up-regulati...
Squamous cell carcinomas of the human anogenital tract are usually associated with infection of specific types of human papillomaviruses (HPV 16, 18, 31, 33, 35). The intracellular concentration of human papillomavirus early gene products E6 and E7 has been directly linked to the proliferative capacity of cervical cancer cells. Since the expression rate of epidermal growth factor receptor corre...
Human blood clotting factor IX, and two chimeric molecules of factor IX, in which the first epidermal growth factor-like domain or both epidermal growth factor-like domains have been replaced by that of human factor X, have been expressed in mouse Cl27 cells. The recombinants have been purified using a metal ion-dependent monoclonal antibody specific for residues l-42 of human factor IX. All re...
A monoclonal antibody of IgG2a isotype (425) is described that reacts with the epidermal growth factor receptor on human cells of different tissue origins. Monoclonal antibody 425 mediates tumor cytotoxicity in vitro using mouse and human effector cells and suppresses in vivo tumor cell growth of epidermoid (A 431) and colorectal (SW 948) carcinoma-derived cell lines. The tumoricidal effects in...
PURPOSE To compare the extent of modulation by various growth factors on clonal growth and differentiation between corneal and stem cell-containing limbal epithelium. METHODS A reported serum-free clonal growth assay was used. The mitogenic response was measured by colony forming efficiency, colony size, and bromodeoxyuridine labelling index; the differentiation was assessed by AE-5 monoclona...
