Detection of transforming growth factor alpha in normal, malignant, and hyperproliferative human keratinocytes
Transforming growth factor alpha (TGF-alpha) is a 50-amino acid peptide, previously demonstrated only in transformed cell lines and human tumors, which is structurally homologous to epidermal growth factor (EGF). TGF-alpha expression in keratinocytes from normal individuals, patients with psoriasis, and patients with malignant skin diseases was investigated using an mAb raised against synthetic...
متن کاملHuman eosinophils express transforming growth factor alpha
Transforming growth factor alpha (TGF-alpha) is a pleuripotential cytokine with diverse biological effects, including the ability to influence the proliferation of normal cells or neoplastic epithelial cells. Eosinophils are a subset of granulocytes that normally enter the peripheral tissues, particularly those beneath gastrointestinal, respiratory, and urogenital epithelium, where they reside ...
متن کاملTransforming growth factor beta1 induces differentiation in human papillomavirus-positive keratinocytes.
Human papillomaviruses (HPVs) are implicated in the etiology of anogenital cancers. Expression of the HPV E6 and E7 oncoproteins is believed to contribute to the carcinogenic process. Progressive loss of the ability to differentiate and resistance to the growth-inhibitory effects of endogenous signals also appear important in multistep tumorigenesis. Transforming growth factor beta1 (TGF-beta1)...
متن کاملActivation of cytosolic phospholipase A2 by transforming growth factor-alpha in HEL-30 keratinocytes.
In the mouse keratinocyte line HEL-30 the epidermal mitogen transforming growth factor-alpha (TGF-alpha) stimulated the rapid release of arachidonic acid in a dose- and time-dependent manner. The liberation of arachidonic acid was due to the activation of a Ca(2+)-dependent cytosolic phospholipase A2 (cPLA2). The activation mechanism critically depended on a functionally active epidermal growth...
متن کاملEpidermal growth factor and transforming growth factor alpha.
This review describes the discovery and initial characterization of the epidermal growth factors (EGFs) and transforming growth factors alpha (TGF alpha), the biosynthesis and tissue distribution of these molecules and a brief description of the effects of these molecules in culture and animals. An analysis of the similarities between the EGFs and TGF alpha s from different organisms is used to...
