Epidermal growth factor receptors

Molecular and Cellular Biochemistry, 1981
EGF-Rs are cell membrane glycoproteins of wide distribution. They have not yet been fully characterized or purified but are probably molecules of 170-190,000 mol. wt. in most cells. The growth factor EGF binds and will saturate cell surface receptors with a KA of about 5 X 10(9) M-1 although a receptor class with an affinity in excess of 10(10) M-1 has

Epidermal Growth Factor Receptor Mutations

Thoracic Surgery Clinics, 2020
Up to 20% of lung adenocarcinomas in the United States and Europe and 50% in Asia have activating mutations of the tyrosine kinase domain of the epidermal growth factor receptor (EGFR). The identification and subsequent targeting of mutations with EGFR-tyrosine kinase inhibitors (TKIs) led to significant advances in treatment of EGFR-mutant lung cancer.

Activation of Epidermal Growth Factor Receptor by Epidermal Growth Factor

Biochemistry, 1996
The binding of epidermal growth factor (EGF) to epidermal growth factor receptor (EGF receptor) induces dimerization of the receptor and activation of its protein tyrosine kinase. Each of these three steps was followed as a function of the concentrations of EGF and of EGF receptor. Binding of EGF was followed by sedimentation of the complex between [3H]

Epidermal Growth Factor, Epidermal Growth Factor Receptors, Intestinal Growth, and Adaptation

Journal of Parenteral and Enteral Nutrition, 1999
Epidermal growth factor (EGF) is an important constituent of several gastrointestinal secretions. Many studies in both animals and humans have shown EGF to have multiple effects upon gut epithelial cells. These include cytoprotection, stimulatory effects on cell proliferation and migration, induction of gene expression such as mucosal enzymes and ...

Epidermal Growth Factor Receptor and Transformation

Surgery Today, 2002
The action of transforming growth factor peptides is mediated by distinct membrane receptors, which in turn activate a postreceptor signaling mechanism, eventually resulting in a mitogenic response. Such a signaling pathway may be modified by oncogene expression at the receptor or postreceptor levels, as well as by alterations in the levels of ...

Epidermal growth factor and its receptor

Molecular and Cellular Endocrinology, 1987
Epidermal growth factor (EGF) binds with high affinity and specificity to a single site on the external domain of its transmembrane receptor to activate the tyrosine protein kinase activity of its cytoplasmic portion. The EGF receptor gene is amplified and over-expressed in several human tumors, suggesting that increased concentrations of the proto ...

Epidermal growth factor receptors in human epidermal tumours

British Journal of Dermatology, 1990
Immunolocalization studies using the strepavidin/biotin peroxidase system were used to identify epidermal growth factor receptors in 10 samples of normal skin, 13 seborrhoeic warts (SW), five lesions of Bowen's disease (BD), 11 solar keratoses (SK), 22 basal cell carcinomas (BCC) and five squamous cell carcinomas (SCC).

Epidermal growth factor and transforming growth factor .alpha. bind differently to the epidermal growth factor receptor

Biochemistry, 1989
Epidermal growth factor (EGF) and transforming growth factor alpha (TGF alpha) compete with each other for binding to the EGF receptor. These two growth factors have similar actions, but there are distinguishable differences in their biological activities. It has never been clear how this one receptor can mediate different responses.

Epidermal Growth Factor Receptor

1995
Abstract The complete nucleotide sequences have been determined for the human EGFR (GenBank accession No X00588), human c-neu (GenBank accession No X03363), human EGFR B3 (HER3, Genbank accession No M29366) and human EGFR B4 (GenBank accession No L07868). Partial sequence information is available for the mouse and chicken EGFRs (Avivi

Overexpression of Epidermal Growth Factor and Epidermal Growth Factor-Receptor mRNAs in Dyshormonogenetic Goiters

Thyroid, 2001
Thyroid malignancy has been induced by long-term endogenous thyrotropin (TSH) stimulation in experimental animals, leading to local and distant metastasis. It has been postulated that constant and prolonged endogenous TSH stimulation in dyshormonogenetic thyroid tissues could result in thyroid neoplasia.
