Regulation of lipid droplet dynamics and lipid homeostasis by hydroxysteroid dehydrogenase proteins
Bin Liang, Lin Fu, Pingsheng Liu
Abstract
The superfamily of hydroxysteroid dehydrogenases (HSDs) has been well-characterized as enzymes in lipid metabolism, and especially in steroid hormone metabolism from bacteria to mammals. Recently, a subset of HSDs members, including 3β-HSD, 11β-HSD, and 17β-HSD, have been shown to be lipid droplet (LD)-associated proteins that are involved in LD dynamics beyond their canonical functions. This review summarizes current understanding of these LD-associated HSD proteins, focusing on how they regulate different LDs with respect to distinct neutral lipids including triacylglycerols (TAGs), cholesterol esters (CEs), and retinyl esters (REs), the evolutionally conserved role of some LD-associated 17β-HSDs in preventing lipolysis, and specific targeting of HSDs for the treatment of metabolic diseases and viral infections.
