Rat mammary carcinoma (RMC) cells derived from serially transplantable mammary tumors are independent of epidermal growth factor (EGF) for long-term growth in serum-free medium. This phenotype is in contrast to that of normal mammary epithelial cells or cells derived from nontransplantable tumors that express an absolute requirement for EGF for growth in culture. The results of the experiments ...
Chronic airway inflammation, one of the pathophysiologic features of bronchial asthma, is suspected to be responsible for irreversible pathological changes of airways, called airway remodeling. To examine the mechanisms of airway remodeling in asthma, we investigated the expression of epidermal growth factor (EGF) and its receptor immunohistochemically in asthmatic human airways. Airway specime...
We found that sterile wounding of human skin induced epidermal expression of the antimicrobial (poly)peptides human beta-defensin-3, neutrophil gelatinase-associated lipocalin, and secretory leukocyte protease inhibitor through activation of the epidermal growth factor receptor. After skin wounding, the receptor was activated by heparin-binding epidermal growth factor that was released by a met...
Cyanogen bromide-cleaved epidermal growth factor (CNBr-EGF) binds to EGF receptors with reduced affinity compared to the native hormone but fails to induce DNA synthesis. However, at similar receptor occupancy, CNBr-EGF is as potent as EGF in activating early cell responses to the hormone. The phosphorylation of membrane proteins, the stimulation of Na+-K+-ATPase as reflected by the ouabain-sen...
