Original Article 4-Hydroxy Estrogen Metabolite, Causing Genomic
Am J Transl Res 2019;11(8):4992-5007 www.ajtr.org /ISSN:1943-8141/AJTR0096694 Original Article 4-Hydroxy estrogen metabolite, causing genomic instability by attenuating the function of spindle-assembly checkpoint, can serve as a biomarker for breast cancer Suyu Miao1,2*, Fengming Yang1*, Ying Wang2*, Chuchu Shao1, David T Zava3, Qiang Ding2, Yuenian Eric Shi1 1Department of Oncology, 2Jiangsu Breast Disease Center, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210000, China; 3ZRT Laboratory, Beaverton 97003, USA. *Equal contributors. Received May 8, 2019; Accepted July 17, 2019; Epub August 15, 2019; Published August 30, 2019 Abstract: Sex hormone metabolism is altered during mammary gland tumorigenesis, and different metabolites may have different effects on mammary epithelial cells. This study aimed to evaluate associations between urinary sexual metabolite levels and breast cancer risk among premenopausal women of Mainland China. The molecular metabolism of the cancer-related metabolites was also explored based on the clinical data. The sex hormone me- tabolites in the urine samples of patients with breast cancer versus normal healthy women were analyzed com- prehensively. Among many alterations of sex hormone metabolisms, 4-hydroxy estrogen (4-OH-E) metabolite was found to be significantly increased in the urine samples of patients with breast cancer compared with the normal healthy controls. This was the most important risk factor for breast cancer. Several experiments were conducted in vitro and in vivo to probe this mechanism. 4-Hydroxyestradiol (4-OH-E2) was found to induce malignant transforma- tion of breast cells and tumorigenesis in nude mice. At the molecular level, 4-OH-E2 compromised the function of spindle-assembly checkpoint and rendered resistance to the anti-microtubule drug. -
Nicotinic Signalling and Neurosteroid Modulation in Principal Neurons of the Hippocampal Formation and Prefrontal Cortex
Nicotinic Signalling and Neurosteroid Modulation in Principal Neurons of the Hippocampal Formation and Prefrontal Cortex by Beryl Yik Ting Chung A Thesis presented to The University of Guelph In partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biomedical Sciences and Neuroscience Guelph, Ontario, Canada © Beryl Yik Ting Chung, April, 2018 ABSTRACT NICOTINIC SIGNALLING AND NEUROSTEROID MODULATION IN PRINCIPAL NEURONS OF THE HIPPOCAMPAL FORMATION AND PREFRONTAL CORTEX Beryl Yik Ting Chung Advisor: University of Guelph, 2018 Dr. Craig D.C. Bailey Nicotinic signalling plays an important role in coordinating the response of neuronal networks in many brain regions. During pre- and postnatal circuit formation, neurotransmission mediated by nicotinic acetylcholine receptors (nAChRs) influences neuronal survival and regulates neuronal excitability, synaptic transmission, and synaptic plasticity. Nicotinic signalling is also necessary for the proper function of the hippocampal formation (HF) and prefrontal cortex (PFC), which are anatomically and functionally connected and facilitate higher-order cognitive functions. The decline or dysfunction in nicotinic signalling and nAChR function has been observed in various neurological disorders, and the disruption or alteration of nicotinic signalling in the HF and/or PFC can impair learning and memory. While the location and functional role of the α4β2* nAChR isoform has been well characterized in the medial portion of the PFC, this is not well-established in the HF. What is the role of α4β2* nAChRs in excitatory principal neurons of the HF during early development? Growing evidence suggests that the progesterone metabolite allopregnanolone (ALLO) plays a role in mediating the proper function of the HF and the PFC, and that it may also inhibit nAChR function. -

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. -

Bioinformation Background Dehydroepiandrosterone (DHEA; androstenolone; 3b-hydroxy-5-androsten-17-one) is a C19 steroid produced in the adrenal cortex and, to a lesser extent, gonads. DHEA serves as a precursor in testosterone and estrogen synthesis. Due to the presence of a 17-oxo (rather than hydroxyl) group, DHEA has relatively weak androgenic activity, which has been estimated at ~10% that of testosterone. However in neonates, peripubertal children and in adult women, circulating DHEA levels may be several- fold higher than testosterone concentrations, and rapid peripheral tissue conversion to more potent androgens (androstenedione and testosterone) and estrogens may occur. Moreover, DHEA has relatively low affinity for sex-hormone binding globulin. These factors may enhance the physiologic biopotency of DHEA. -

Insulin Enhances ACTH-Stimulated Androgen and Glucocorticoid Metabolism in Hyperandrogenic Women
European Journal of Endocrinology (2011) 164 197–203 ISSN 0804-4643 CLINICAL STUDY Insulin enhances ACTH-stimulated androgen and glucocorticoid metabolism in hyperandrogenic women Flavia Tosi, Carlo Negri, Elisabetta Brun, Roberto Castello, Giovanni Faccini1, Enzo Bonora, Michele Muggeo, Vincenzo Toscano2 and Paolo Moghetti Division of Endocrinology and Metabolism and 1Clinical Chemistry Laboratory, University and Azienda Integrata Ospedaliera Universitaria di Verona, P.le Stefani 1, 37126 Verona, Italy and 2Division of Endocrinology, Ospedale Sant’Andrea, University La Sapienza, Ospedale Sant’Andrea, Via Di Grotta Rossa 1035, 00189 Rome, Italy (Correspondence should be addressed to P Moghetti; Email: [email protected]) Abstract Objective: In hyperandrogenic women, hyperinsulinaemia amplifies 17a-hydroxycorticosteroid intermediate response to ACTH, without alterations in serum cortisol or androgen response to stimulation. The aim of the study is to assess whether acute hyperinsulinaemia determines absolute changes in either basal or ACTH-stimulated adrenal steroidogenesis in these subjects. Design and methods: Twelve young hyperandrogenic women were submitted in two separate days to an 8 h hyperinsulinaemic (80 mU/m2!min) euglycaemic clamp, and to an 8 h saline infusion. In the second half of both the protocols, a 4 h ACTH infusion (62.5 mg/h) was carried out. Serum cortisol, progesterone, 17a-hydroxyprogesterone (17-OHP), 17a-hydroxypregnenolone (17-OHPREG), DHEA and androstenedione were measured at basal level and during the protocols. Absolute adrenal hormone secretion was quantified by measuring C19 and C21 steroid metabolites in urine collected after the first 4 h of insulin or saline infusion, and subsequently after 4 h of concurrent ACTH infusion. Results: During insulin infusion, ACTH-stimulated 17-OHPREG and 17-OHP were significantly higher than during saline infusion.
