Myelodysplastic syndrome (MDS) is the disorder of hematopoietic stem cells. In MDS patients, leukemia progression is also associated with iron overload. Hydroxybutyrate dehydrogenase type 2 (BDH2) catalyzes the production of 2,5-dihydroxybenzoic acid (DHBA), an iron-binding component. In the present study, we assessed whether BDH2 can serve as a predictor for leukemia progression in MDS. The higher BDH2 expression (15%) group showed a greater risk for leukemia progression than the lower expression group (3.18%) (P=0.017). Additionally, we investigated the mechanism underlying the prognostic ability of BDH2 by using RNA interference–mediated-knockdown of BDH2 (BDH2-KD) in the acute leukemia cell line, THP1. Cell cycle analysis, surface markers, and special stain studies indicated that BDH2-KD induced differentiation and decreased the growth rate of THP1 cells, which was associated with the retardation of cell cycle. Under next-generation sequences analysis, we also found some candidate genes involving iron metabolism pathway contribute to leukemia transformation in MDS patients. Our study provides a foundation for further research on the role of BDH2 and iron metabolism in the pathogenesis of MDS.
