Adropin - physiological and pathophysiological role

Area of Science:

• Endocrinology
• Metabolic Research
• Molecular Biology

Background:

• Adropin is a 76-amino acid peptide hormone discovered in 2008.
• Its amino acid sequence is identical across humans, mice, and rats.
• Adropin is encoded by the Enho gene, primarily expressed in the liver and central nervous system.

Purpose of the Study:

• To provide an overview of the existing literature on adropin.
• To explore the role of adropin in physiological and pathophysiological conditions.
• To highlight the need for further research into adropin's exact functions and mechanisms.

Main Methods:

• Literature review of existing studies on adropin.
• Analysis of reported findings on adropin's presence in various tissues and body fluids.
• Synthesis of data regarding adropin's involvement in metabolic and cardiovascular functions.

Main Results:

• Adropin is implicated in energy homeostasis and the regulation of glucose and fatty acid metabolism.
• Conflicting evidence exists regarding whether adropin is secreted or membrane-bound.
• Adropin levels change in various physiological and pathophysiological states and is found in diverse tissues and fluids.

Conclusions:

• Adropin is involved in carbohydrate-lipid metabolism, metabolic diseases, CNS function, endothelial function, and cardiovascular disease.
• The precise physiological roles and mechanisms of adropin require further investigation.
• Understanding adropin is crucial for potential therapeutic strategies in metabolic and cardiovascular diseases.
