MicroRNAs (miRNAs) are small non-coding RNA molecules and play an important role in the post-transcriptional regulation of gene expression and thereby influence important cellular functions. In adipocytes, miRNAs regulate key processes such as differentiation, inflammation, metabolism, and adipokine secretion. Recently, we found that miR-27a is upregulated under proinflammatory conditions in human adipocytes. Thus, our goal was to better understand the function of miR-27a in a...

Background: Functional studies on uncoupling protein 1 (UCP1) are important to identify potential pharmacological targets which interfere with energy metabolism. However, current cell models of human origin are scarce due to limited tissue availability. In this study, we generated human preadipocytes and adipocytes with an overexpression of UCP1 and studied the metabolic function of these cells.Methods: Human Simpson-Golabi-Behmel syndrome (SGBS) cells w...
