In the past decade application of novel research techniques including recombinant DNA technology have paved the way to understand the mechanisms of insulin action and its alterations at the molecular level. The first step in insulin action is the activation of the insulin receptor. The insulin receptor is a tetrameric protein consisting of two extracellular alpha- and two transmembrane beta-subunits. Binding of insulin to the alpha-subunit causes autophosphorylation of the intracellular beta-subunit region on tyrosine residues thereby activating the receptor. How the hormonal signal is subsequently transduced within the cell is still quiet unclear. The activated insulin receptor appears to couple to cytosolic receptor substrates which can affect different signaling cascades eliciting the pleiotropic hormone response on cell metabolism and growth. Most proteins involved in the signal transduction pathway of insulin are not known yet, but each of them might play a role in the various forms of insulin resistance. Taking the insulin receptor as an exemplary protein involved in insulin action we review molecular mechanisms regulating insulin receptor activity, gene expression, and the role of natural occurring insulin receptor gene mutations in patients with insulin resistant diabetes mellitus. It is outlined how the combination of both clinical medicine and molecular biology not only helps to understand insulin action and the pathogenesis of insulin resistance, but also leads to new avenues in the differential diagnosis, therapy, and possibly prevention of this heterogenous but most frequent metabolic and endocrine disorder.</p>","PeriodicalId":12104,"journal":{"name":"Experimental and clinical endocrinology","volume":"101 1","pages":"17-29"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0029-1211203","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19461264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell-specific expression of the pancreatic islet hormone genes is conferred by a cell-specific combination of transcription factors. The DNA binding sites and cDNAs of some of them have been characterized. An islet-specific enhancer-binding protein of the rat glucagon gene recognizes also cis-acting elements of the rat insulin I and rat somatostatin genes. Thus identical or related factors may be involved in the expression of these pancreatic genes, reflecting that the different islet cell types arise from a common progenitor cell. The characterization of islet-specific transcription factors may lead to regulatory genes whose products specify islet cell phenotypes during development. Basal transcriptional activity of islet hormone genes can be enhanced by metabolic, humoral or nerve signals via various second messenger systems. Cyclic AMP acts through distinct response elements.
