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...

context triple negative breast cancer (tnbc) is a heterogeneous group of diseases that is negative for esterogen receptor (er) progesteron receptor (pr) and human epidermal growth factor receptor 2 (her2). this type of breast cancer is typically high-grade carcinomas, although low-grade tumors occur. the aim of this review is to focus on molecular classification and features, prognostic markers...

Purpose: We investigated the antitumor activity of the combination of two different humanized monoclonal human epidermal growth factor receptor (HER) 2 antibodies, pertuzumab and trastuzumab,

A monoclonal antibody to the epidermal growth factor (EGF) receptor of A431 cells, denoted 2Dl-IgM, was generated after fusion of immunized BALB/c mouse spleen cells with SpZ/O-Ag14 myeloma cells, Specific binding of 2D1-IgM to the A431 cell-surface receptor for EGF was demonstrated by indirect immunofluorescence, immunoprecipitation, and immunoblot analysis. Scatchard analysis of lz6I-EGF bi...

Management of patients with metastatic hormone receptor-positive breast cancer poses a challenge due to the inevitable development of endocrine resistance. Hormone resistance is associated with a complex interaction of the estrogen receptor with growth factors, transmembrane receptors, and intracellular growth cascades. The PI3K/Akt/mTOR pathway plays a major role in hormone resistance and prol...

Members of the human epidermal growth factor receptor (HER) family—epidermal growth factor receptor (EGFR, HER1), HER2, HER3, and HER4—are transmembrane tyrosine kinase receptors that are important mediators of cell growth, development, and survival. Activation of the HER tyrosine kinases triggers intracellular signaling pathways, including the MAPK and PI3K-Akt pathways (Olayioye et al., 2000)...

Purpose: We investigated the antitumor activity of the combination of two different humanized monoclonal human epidermal growth factor receptor (HER) 2 antibodies, pertuzumab and trastuzumab,

A cancer stem cell population in malignant brain tumors takes an essential part in brain tumor initiation, growth, and recurrence. Growth factors, such as epidermal growth factor, fibroblast growth factor-2, vascular endothelial growth factor, platelet-derived growth factor, and hepatocyte growth factor, are shown to support the proliferation of neural stem cells and also may play key roles in ...

Women with hormone receptor-positive, human epidermal growth factor receptor 2- negative breast cancer-the most common subtype-have new options as palbociclib and similar drugs debut. This article outlines the rationale and evidence for their use.
