  2. 6. Regulation of apoptosis and steroidogenesis in ovarian preovulatory granulosa cells

    Author : Eva Svensson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; granulosa cells; luteinizing hormone; progesterone receptor; RU 486; Org 31710; leptin; steroidogenesis;

    Abstract : Only a minute fraction of ovarian follicles present in a foetal ovary will complete the path to ovulation. The majority of the follicles will instead undergo atresia, a hormonally controlled apoptotic process. Apoptosis occurs throughout follicle development, with an extensive reduction in the number of follicles present at birth. READ MORE

  4. 7. Adjuvant tamoxifen and luteinizing hormone-releasing hormone agonists in premenopausal breast cancer : on long-term benefits and side effects in a randomised study

    Author : Ásgerður Sverrisdóttir; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Adjuvant endocrine therapy improves breast cancer survival, unconditional of other treatment. In premenopausal breast cancer, tamoxifen for 5 years is the standard treatment, with or without the addition of ovarian ablative therapy. READ MORE

  5. 8. The role of the prostate in androgen metabolism

    Author : Mats Olsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The androgenic steroid hormones are essential for the physiological development of the prostate gland and are also implicated in pathological processes such as benign prostatic hyperplasia and prostate cancer. The systemic effect of endocrine activity in the prostate gland has so far been considered of minor importance. READ MORE

  6. 9. Regulation of Leptin by Sexual Maturation and Energy Status in Male Atlantic Salmon (Salmo salar L.) Parr
