  2. 1. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Author : Johan Lundqvist; Kjell Wikvall; Maria Norlin; Magnus Ingelman-Sundberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal steroidogenesis; CYP7B1; vitamin D; calcitriol; enzymatic regulation; transcriptional regulation; CYP21A2; aromatase; sex hormone; estrogen; androgen; nuclear receptor; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

  4. 2. Influences of Endogenous and Exogenous Hormones in Middle-aged Women

    Author : Ali Khatibi Esfanjani; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipid profile; Blood pressure; Non-hormonal drug; Middle-aged women; Cardiovascular disease; Menopause; Androstendione; Androgen; Testosterone;

    Abstract : Endogenous and exogenous sex hormones are of pivotal importance for women’s health. Hormone therapy has been widely studied but there is limited data about androgen and androgen replacement therapy. READ MORE

  5. 3. Androgen receptors and endocrine disrupting substances

    Author : Anders Larsson; Per-Erik Olsson; Björn Brunström; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Androgen receptor; Brominated flame retardant; TBECH; Endocrine disruptor; Biology; Biologi; NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi;

    Abstract : Throughout the animal kingdom, organisms are dependent on substances such as steroid hormones to help them maintain internal balances. Examples of important tasks that are under regulation of steroid hormones are somatic and gonadal development, sexual performance and behavior (both social and sexual) as well as sex differentiation.

  6. 4. Impact of Lifestyle, Hormones, and Genes on Breast Cancer

    Author : Maria Hietala; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; BRCA1; BRCA2; androgen receptor; CAG; GGC; polymorphism; htSNP; oral contraceptives; testosterone; breast-feeding; prolactin; premenopausal women; CYP2D; complementary and alternative medicin; antidepressants;

    Abstract : Approximately 7000 women are diagnosed and 1500 women die from breast cancer in Sweden every year. The aim of this thesis was to study the interplay of polymorphisms, hormone levels, lifestyle, and the use of concomitant medication in relation to risk and prognosis in two cohorts: one composed of young healthy women from high-risk breast cancer families and the other of breast cancer patients from the general population.

  7. 5. Maternal programming: costs, benefits and constraints of maternal hormone transfer

    Author : Michael Tobler; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; aves; immune function; behavior; Maternal effects; hormones;

    Abstract : Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. READ MORE
