Emerging Roles of Dehydrogenase/reductase Member 2 (DHRS2) in the Pathology of Disease

Dehydrogenase/reductase member 2 (DHRS2) belongs to the short-chain dehydrogenase/reductase (SDR) family. It was initially isolated from the nuclear extract of hepatocellular carcinoma HepG2 cells and was identified as a specific cell cycle regulator. DHRS2 is a reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent carbonyl reductase and catalyzes the reduction of dicarbonyl compounds. It is also functionally active in lipid metabolism and acts as a metabolic enzyme of hormones. Recent studies have shown that DHRS2 reprograms lipid metabolism and redox homeostasis to regulate proliferation, migration, invasion, and drug resistance of cancer cells. Here, we describe the structure, organelle localization and function of DHRS2, and also highlight its roles in the pathologic progression of diseases.
