http://purl.uniprot.org/citations/2401457http://www.w3.org/2000/01/rdf-schema#comment"We studied the regulation of the epidermal growth factor receptor mRNA and the number of epidermal growth factor binding sites in subcellular compartments involved in the biosynthesis and endocytosis of the epidermal growth factor receptor during the prereplicative phase of liver regeneration. The epidermal growth factor receptor mRNA, quantified by solution hybridization, decreased after partial hepatectomy, with a nadir of about 35% 18 hr after hepatectomy. An even stronger decrease in the number of epidermal growth factor binding sites after partial hepatectomy was observed in a Golgi-enriched low-density membrane fraction, reflecting available newly synthesized epidermal growth factor receptors. It is suggested that this decrease in newly synthesized available epidermal growth factor receptors is caused primarily, but not entirely, by decreased epidermal growth factor receptor mRNA levels and the additional down-regulation of epidermal growth factor binding sites may involve posttranslational mechanisms such as intracellular occupation by transforming growth factor-alpha. The observation that the number of specific epidermal growth factor binding sites after partial hepatectomy was only moderately reduced in prelysosomal endosomes and in lysosomes, compared with the newly synthesized receptors, may indicate that a pool of receptors targeted for lysosomes exists and these receptors are regulated in a different manner than the receptor pool targeted for the cell surface. Furthermore, at least two separable endocytic subcompartments are involved in the transport of the epidermal growth factor/epidermal growth factor receptor complex in the liver.(ABSTRACT TRUNCATED AT 250 WORDS)"xsd:string
