  1. 31. Steroids and steroid-metabolizing enzymes in the nervous system : Special focus on cell survival and sex hormone synthesis

    Författare :Ida Emanuelsson; Maria Norlin; Kjell Wikvall; Lena Ekström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemi; Biochemistry;

    Sammanfattning : Some steroids in the brain and peripheral nervous system have been shown to have neuroprotective effects but the knowledge is limited. The present study examines the effects of steroids including oxysterols, vitamin D and vitamin D analogs on cell viability/growth and steroidogenesis in the nervous system. LÄS MER

  3. 32. Ovarian tumours, cell isolation, cell survival and sex steroids

    Författare :Magdalena Taube; Seija Grénman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Obstetrik och gynekologi; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background: Ovarian cancer is the most deadly malignancy of the female reproductive tract. Ovarian epithelial tumours are considered to be endocrine related, but the factors that govern their genesis and progression remain unclear. Radical surgery and recent advances in chemotherapy have only moderately improved survival rates. LÄS MER

  7. 35. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS

    Författare :Jessica Strömberg; Per Lundgren; Torbjörn Bäckström; David Haage; Esa Korpi; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; allopregnanolone; chloride ion uptake; patch-clamp; 3beta-steroids; kinetic parameters; rat brain; Obstetrics and gynaecology; Obstetrik och gynekologi;

    Sammanfattning : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. LÄS MER
