The rat ovary contains two isozymes of 20 alpha-hydroxysteroid dehydrogenase (HSD-1 and HSD-2). In this study, the expression of activity of each isozyme was investigated in ovaries that contained a single generation of corpora lutea during pseudopregnancy. This condition was induced by cervical stimulation in rats that had been rendered anovulatory by housing them in a continuously lit environment. The total activity of cytosolic 20 alpha-HSD was lower in the ovaries of these pseudopregnant rats than in ovaries containing multiple generations of corpora lutea. In normal pseudopregnancy, HSD-1 activity was low on days 5 and 9 and increased markedly on day 15, whereas HSD-2 was lower than HSD-1 and did not vary throughout pseudopregnancy. However, on days 5 and 9 of continuous-light pseudopregnancy, low activity of HSD-1 only was detected; by day 15, HSD-1 activity had increased sixfold and HSD-2 activity could be detected. Immunohistochemical methods using a specific antibody recognizing both HSD-1 and HSD-2 revealed that the number of 20 alpha-HSD-positive luteal cells increased by day 15. Thus, the increase in total enzyme activity and appearance of HSD-2 activity observed at late pseudopregnancy was accompanied by an increase in the number of 20 alpha-HSD-positive luteal cells. << Less

Molecular cloning and characterization of the human and mouse UDP-glucose dehydrogenase genes.
Spicer A.P., Kaback L.A., Smith T.J., Seldin M.F.

The enzyme UDP-glucose dehydrogenase (Udpgdh) (EC 1.1.1.22) converts UDP-glucose to UDP-glucuronate, a critical component of the glycosaminoglycans, hyaluronan, chondroitin sulfate, and heparan sulfate. Although Udpgdh is a comparatively well characterized enzyme, no vertebrate genes encoding this enzyme have been reported to date. We report the cloning and characterization of the human and mouse UDP-glucose dehydrogenase genes. Mouse and human cDNAs predicted proteins of 493 and 494 amino acids, 24-25 residues longer at their carboxyl termini than the previously reported bovine Udpgdh sequence. The mouse Ugdh gene is composed of 10 exons, spanning 15 kilobases. Northern analyses indicated widespread expression of the gene in embryo and adult. Through interspecific backcross analyses, we localized the Ugdh gene to mouse chromosome 5 at approximately 39 centimorgans, suggesting that the human UGDH gene is localized to chromosome 4p13-15. Results from Southern analyses strongly suggest that Udpgdh is encoded by a single gene in the mouse. Transfection of mouse Ugdh expression vectors led to an increase in detectable Udpgdh activity in mammalian cells. Preliminary expression studies indicated that proinflammatory cytokines, such as interleukin 1beta, can substantially increase the expression of human UGDH in cultured human fibroblasts, suggesting that glycosaminoglycan biosynthesis may be partly regulated by the availability of activated UDP-glucuronate, as determined by relative Udpgdh expression levels. << Less

The paper describes chemical synthesis of uridine diphosphate 2-deocyglucose (UDPdGLc) through reaction of uridine 5'-phosphomorpholidate with 2-deoxy-a-D-glucopyranosyl phosphate. The prepared analog of uridine diphosphate glucose (UDPGlc) served as a substrate for calf liver UDPGlc dehydrogenases (EC 1.1.1.22), the reaction product was identified as nucleotide deoxyhexuronic acid derivative. The apparent Km for UDPdGlc was found to be 60 times that of UDPGlc, and the relative V value for the analog was 0.09. The peculiar lag-eriod in reaction kinetics has been observed for the analog and is presumably connected with the slow rate of the initial stages of the reaction. UDPdGlc was found to be quite an efficient substrate for UDPGlc 4-epimerases (EC 5.13.2) from yeast, calf liver and mung bean seedlings. << Less
