The enzyme 20α-hydroxysteroid dehydrogenase (20α-HSD) catalyzes the conversion of progesterone to its inactive form, 20α-hydroxyprogesterone. This enzyme plays a critical role in the regulation of luteal function in female mammals. In this study, we conducted the characterization and functional analyses of bovine 20α-HSD from placental and ovarian tissues.(More)
BACKGROUND The aldo-keto reductase family 1 member C1 (AKR1C1) belongs to a superfamily of NADPH-dependent reductases that convert a wide range of substrates, including carbohydrates, steroid hormones, and endogenous prostaglandins. The 20 alpha-hydroxysteroid dehydrogenase (20 alpha-HSD) is a member of AKR family. The aims of this study were to determine(More)
This study was conducted to characterize and functionally analyze the monkey 20α-hydroxysteroid dehydrogenase (20α-HSD) in the ovary, placenta, and oviduct. We focused on 20α-HSD mRNA expression and protein localization in monkey reproductive tissues and the molecular characterization of the promoter region. Reverse transcription-polymerase chain reaction(More)
BACKGROUND Dimeric human erythropoietin (dHuEPO) peptides are reported to exhibit significantly higher biological activity than the monomeric form of recombinant EPO. The objective of this study was to produce transgenic (tg) mice expressing dHuEPO and to investigate the characteristics of these mice. METHODS A dHuEPO-expressing vector under the control(More)
