  1. 1. Molecular mechanisms of estrogen and antiestrogen action

    Författare :Tomas Barkhem; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Estrogen receptor; SHBG; tamoxifen; raloxifene; pS2; p1 60 coactivator; SRC-1; TIF-2;

    Sammanfattning : Estrogen is a key regulatory hormone that affects numerous physiological processes. The estrogen receptors (ER), ER alpha and ER beta, play a central role in mediating the effects of both estrogens and antiestrogens. Estrogen signaling has proven to be multifaceted and the precise mechanism of action remains in many cases elusive. LÄS MER

  3. 2. Analysis of DNA adducts formed by tamoxifen and related antiestrogenic and estrogenic compounds in rats

    Författare :Heli Rajaniemi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DNA adducts; 32P-postlabelling; tamoxifen; toremifene; diethylstilbestrol; clomiphene; triparanol; raloxifene; antiestrogen; estrogen; SERM; genotoxicity; cancer;

    Sammanfattning : The work presented herein has focused on DNA adduct formation by the non-steroidal antiestrogen tamoxifen and its analogues. Tamoxifen, [(Z)-1-{4-[2-(dimethylamino)-ethoxy]phenyl}-1,2-diphenyl-1-butene], is widely used in the treatment of breast cancer and its recognised side effect is endometrial cancer. LÄS MER

  4. 3. Estrogen receptor b in the urogenital tract of both male and female

    Författare :Zhang Weihua; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The central finding of this thesis is that estrogen receptors regulate androgen receptor expression: ERalpha unpregulates AR and ERbeta down-regulates AR. With this theme, we explored the physiological role of an ER-AR pathway, especially ERbeta-AR, in some urogenital tissues, uterus, ovary and prostate, using ERbeta knockout mice. LÄS MER

  5. 4. Biochemical and Structural Studies on the Adaptor Protein p130Cas

    Författare :Fariborz Nasertorabi; Kathryn R Ely; Lars Liljas; Jyrki Heino; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Integrin signaling; p130Cas; X-ray Crystallography; NMR Spectroscopy; Protein phosphorylation; BCAR-1; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Crk associated substrate (Cas) is an adaptor protein that becomes phosphorylated upon integrin signaling and influences regulation of cell processes such as migration, proliferation and survival. It consists of multiple domains and regions that can interact with several signaling proteins involved in different signaling pathways. LÄS MER

  7. 5. Hormonal regulation of hepatic cholesterol and lipoprotein metabolism : effects of estrogen and growth hormone

    Författare :Paolo Parini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aging; atherosclerosis; bile acids; estrogen; estrogen receptor; cholesterol; growth hormone; growth hormone receptor; cholesterol 7[alpha]-hydroxylase; high density lipoprotein; hydroxy-methylglutaryl-coenzyme A reductase; hormones; hypercholesterolemia; hypophysectomy; insulin-like growth factor-I; low density lipoproteins;

    Sammanfattning : Coronary heart disease is the result of the progression of atherosclerotic lesions, and represents the major cause of death in western countries. Age, male sex, plasma cholesterol, hypertension and smoking are major risk factors for atherosclerosis. LÄS MER
