Dehydroepiandrosterone Sulfate (DHEAS) Stimulates the First Step in the Biosynthesis of Steroid Hormones
Dehydroepiandrosterone Sulfate (DHEAS) Stimulates the First Step in the Biosynthesis of Steroid Hormones Jens Neunzig, Rita Bernhardt* Department of Biochemistry, Faculty of Technical and Natural Sciences III, Saarland University, Saarbru¨cken, Germany Abstract Dehydroepiandrosterone sulfate (DHEAS) is the most abundant circulating steroid in human, with the highest concentrations between age 20 and 30, but displaying a significant decrease with age. Many beneficial functions are ascribed to DHEAS. Nevertheless, long-term studies are very scarce concerning the intake of DHEAS over several years, and molecular investigations on DHEAS action are missing so far. In this study, the role of DHEAS on the first and rate-limiting step of steroid hormone biosynthesis was analyzed in a reconstituted in vitro system, consisting of purified CYP11A1, adrenodoxin and adrenodoxin reductase. DHEAS enhances the conversion of cholesterol by 26%. Detailed analyses of the mechanism of DHEAS action revealed increased binding affinity of cholesterol to CYP11A1 and enforced interaction with the electron transfer partner, adrenodoxin. Difference spectroscopy showed Kd-values of 4062.7 mM and 24.860.5 mM for CYP11A1 and cholesterol without and with addition of DHEAS, respectively. To determine the Kd-value for CYP11A1 and adrenodoxin, surface plasmon resonance measurements were performed, demonstrating a Kd-value of 3.060.35 nM (with cholesterol) and of 2.460.05 nM when cholesterol and DHEAS were added. Kinetic experiments showed a lower Km and a higher kcat value for CYP11A1 in the presence of DHEAS leading to an increase of the catalytic efficiency by 75%. These findings indicate that DHEAS affects steroid hormone biosynthesis on a molecular level resulting in an increased formation of pregnenolone. -
Excretion Patterns of Fecal Progestagens, Androgen and Estrogens During Pregnancy, Parturition and Postpartum in Okapi (Okapia Johnstoni)

The aim of the present study was to establish a simple method to monitor ovarian activity and non-invasively diagnose pregnancy in okapi (Okapia johnstoni). The feces of a female okapi were collected daily or every 3 days for 28 months. Steroids in lyophilized feces were extracted with 80% methanol, and the fecal levels of immunoreactive progestagens (progesterone and pregnanediol- glucuronide), androgen (testosterone), and estrogens (estradiol-17β and estrone) were determined by enzyme immunoassays with commercially available antisera. Using the progesterone profiles, the durations of the luteal phase, follicular phase, and estrous cycle were determined to be 11.1 ± 0.4, 5.3 ± 0.6, and 16.5 ± 0.7 days (n=22), respectively. Fecal levels of immunoreactive progesterone, pregnanediol glucuronide, and testosterone gradually increased from early pregnancy and peaked several months before parturition. More pregnanediol glucuronide was excreted in feces than progesterone during late pregnancy, but not during the estrous cycle. Although the fecal concentrations of immunoreactive estradiol-17β and estrone change a little throughout pregnancy and non-pregnancy, they rose sharply and temporarily on the day following parturition. -

STUDIES TOWARDS THE DEVELOPMENT OF A MULTI PURPOSE HOME SELF-TEST KIT FOR THE DETECTION OF URINARY TETRAHYDROCORTISONE AND TESTOSTERONE METABOLITES A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University Claire Margaret Nielsen 2003 ii Abstract The development of homogeneous enzyme immunoassays (HEIA) for testosterone glucuronide (TG) and tetrahydrocortisone glucuronide (THEG) in urine are described. The proposed test system is based on the Ovarian Monitor homogeneous immunoassay system, established by J.B Brown and L.F. Blackwell et al. 1 as a simple, laboratory accurate, monitoring device for the measurement of estrone glucuronide (E1G) and pregnanediol glucuronide (PdG) as markers of the fertile phase during a womans menstrual cycle. This information can be used readily by women to identify their cyclical periods of fertility and infertility. The major testosterone metabolite in the urine of males, testosterone p-glucuronide, was synthesised by firstly preparing the glycosyl donor a-bromosugar and conjugating this with testosterone under standard Koenigs-Knorr conditions. 1H nmr studies confirmed that the synthetic steroid glucuronide had the same stereochemistry as the naturally occurring urinary testosterone glucuronide. Testosterone glucuronide and tetrahydrocortisone glucuronide conjugates of hen egg white lysozyme were prepared using the active ester coupling method in good yield. Unreacted lysozyme was successfully removed from the reaction mixture by a combination of cation exchange chromatography in 7 M urea and hydrophobic-interaction chromatography. -

Scientists are constantly striving to find new tools to assess their welfare, in order to ameliorate husbandry conditions, leading to a better life and scientific data. Steroid hormones can provide information regarding different behavioral tracts of laboratory animals but their quantification often require stressful sampling procedures. Hair represents a good, less invasive, alternative in such scenario and is also indicative of longer timespan due to hormones’ accumulation. The aim of the work was to quantify steroid hormones in the hair of male laboratory mice and to look for differences imputable to age and housing conditions (pairs VS groups). Age influenced all analysed hormones by increasing testosterone and dehydroepiandrosterone (DHEA) levels and decreasing corticosterone.
