Abstract:

Advanced glycation end-products (AGEs) are involved in mediating the effects of hyperglycaemia in diabetes. The most important receptor for AGEs is the receptor for advanced glycation end-products (RAGE). Binding of AGEs to RAGE converts transient cellular stimulation into sustained cellular dysfunction driven by long-term activation of the proinflammatory transcription factor NF-kB. Different splice variants of RAGE exist, including a soluble form that binds to AGEs but lacks the intracellular domain and thus fails to induce signal transduction. In this context, soluble RAGE may act as a therapeutic agent for AGE-induced effects. The balance between the synthesis of sRAGE and full-length RAGE may be an important determinant of AGE-induced dysfunction. An increasing amount of evidence suggests that AGEs either directly or via their interaction with RAGE play a pivotal role in the development and acceleration of atherosclerotic cardiovascular disease. These effects will be summarised in this review, together with the effects of therapeutic strategies targeting AGE/RAGE interactions. These treatments appear to have significant clinical potential, most likely in combination with currently used agents such as inhibitors of the renin-angiotensin system or statins, to reduce the major burden of diabetes, its associated cardiovascular disease.

More about this publication?
  • Cardiovascular & Hematological Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in cardiovascular and hematological disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will contain a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in cardiovascular and hematological disorders. As the discovery, identification, characterization and validation of novel human drug targets for cardiovascular and hematological drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
