Abstract:
Obesity and lipoatrophy are major risks for insulin resistance, type 2 diabetes and cardiovascular diseases. The molecular links between adipocyte dysfunction and metabolic disorders were elusive until the discovery that adipose tissue operates as an endocrine organ and releases factors targeting a wide range of organs. This article attempts to review the more recent advances from research on the transcriptional control of adipogenesis and on new adipocyte-secreted proteins that have been proposed as molecular links between adipose tissue and insulin resistance.
Insights
Adipose tissue dysfunction, linked to obesity and lipoatrophy, contributes to insulin resistance and type 2 diabetes. Recent research highlights transcriptional control of adipogenesis and novel adipocyte proteins as key molecular links.
Area of Science:
