  1. 1. Steroid-Metabolizing Cytochrome P450 (CYP) Enzymes in the Maintenance of Cholesterol and Sex Hormone Levels

    Author : Hanna Pettersson; Maria Norlin; Kjell Wikvall; Paolo Parini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP27A1; CYP7B1; cytochrome P450; estrogen receptor; androgen receptor; cholesterol; sex hormone; hydroxylation; steroid metabolism; regulation of steroid levels; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : The enzymes CYP27A1 and CYP7B1 are widely expressed in various human tissues and perform catalytic reactions in cholesterol homeostasis and endocrine signaling. We have investigated the metabolism of a synthetic oxysterol. READ MORE

  2. 2. Equine glutathione transferase A3-3 : an efficient steroid isomerase

    Author : Helena Lindström; Bengt Mannervik; Ann-Kristin Östlund Farrants; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Equine; glutatione transferase; steroidogenesis; steroid isomerase; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. READ MORE

  3. 3. Exploring vitamin D and steroid hormone receptors – from healthy elderly to prostate cancer cells

    Author : Maria Araceli Diaz Cruz; Maria Faresjö; Dennis Larsson Dennis Larsson; Johan Staaf; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vitamin D; steroid hormone receptors; lifestyle; methylation; SNPs; healthy elderly; prostate cancer cells; crosstalk; PDIA3;

    Abstract : The genetic background together with environmental factors and lifestyle are key contributors to the health of an individual. Genetic background is inherited and irreversible unless mutations occur. However, lifestyle habits (i.e. READ MORE

  4. 4. Growth Hormone and Anabolic Androgenic Steroids : Effects on Neurochemistry and Cognition

    Author : Alfhild Grönbladh; Mathias Hallberg; Jörgen Isgaard; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; anabolic androgenic steroids; nandrolone decanoate; insulin-like growth factor; GABAB; opioids; memory; water maze; autoradiography; central nervous system; rats; Biological Research on Drug Dependence; Biologisk beroendeforskning;

    Abstract : Growth hormone (GH) stimulates growth and metabolism but also displays profound effects on the central nervous system (CNS). GH affects neurogenesis and neuroprotection, and has been shown to counteract drug-induced apoptosis in the brain. READ MORE

  5. 5. Sex steroid hormone receptors : inner ear and hearing

    Author : Rusana Simonoska; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It is well known that hearing loss is more profound in elderly males than females, regardless of noise exposure. Also, an age-related hearing decline starts much earlier in males, already after the age of 30, while in women, the decline does not start until the age of 50. READ MORE
