The dual oxidases (DUOXes) 1 and 2 are named based on their having both a domain homologous to the NADPH-oxidase of the phagocyte NADPH-oxidase gp91( phox )/NOX2 and a domain homologous to thyroid peroxidase. The DUOX1 and DUOX2 mRNAs were originally cloned from thyroid tissue, and the corresponding proteins were recognized as intricate components of the(More)
LNCaP prostate tumor cells contain an abnormal androgen receptor system. Progestagens, estradiol and anti-androgens can compete with androgens for binding to the androgen receptor and can stimulate both cell growth and excretion of prostate specific acid phosphatase. We have discovered in the LNCaP androgen receptor a single point mutation changing the(More)
Thyroid hormones are essential for fetal development. T4 can be activated by type I (ID-I) and type II (ID-II) iodothyronine deiodinase or inactivated by type III deiodinase (ID-III). The influence of placental ID-II and ID-III on the regulation of fetal thyroid hormone levels was investigated. Using [125I]T4 and [125I]T3, respectively, ID-II and ID-III(More)
The human prostate tumor cell line LNCaP contains an abnormal androgen receptor system with broad steroid binding specificity. Progestagens, estradiol and several antiandrogens compete with androgens for binding to the androgen receptor in the cells to a higher extent than in other androgen sensitive systems. Optimal growth of LNCaP cells is observed after(More)
Pendred syndrome is an autosomal recessive disorder characterized by early childhood deafness and goiter. A century after its recognition as a syndrome by Vaughan Pendred, the disease gene ( PDS ) was mapped to chromosome 7q22-q31.1 and, recently, found to encode a putative sulfate transporter. We performed mutation analysis of the PDS gene in patients from(More)
BACKGROUND Biomarkers have been proposed for identification of women at increased risk of developing pre-eclampsia. OBJECTIVES To investigate the capacity of circulating placental growth factor (PlGF), vascular endothelial growth factor (VEGF), soluble fms-like tyrosine kinase-1 (sFLT1) and soluble endoglin (sENG) to predict pre-eclampsia.

BACKGROUND Several genetic defects are associated with permanent congenital hypothyroidism. Immunologic, environmental, and iatrogenic (but not genetic) factors are known to induce transient congenital hypothyroidism, which spontaneously resolves within the first months of life. We hypothesized that molecular defects in the thyroid oxidase system, which is(More)
The complete coding region of the human androgen receptor gene has been isolated from a genomic library. The information for the androgen receptor was found to be divided over eight exons and the total length of the gene exceeded 90 kb. The sequence encoding the N-terminal region is present in one large exon. The two putative DNA-binding fingers are encoded(More)
Thyroid peroxidase (TPO) is a heme binding protein localized on the apical membrane of the thyrocyte. TPO enzymatic activity is essential for thyroid hormonogenesis. Inactivating mutations form the molecular basis for a specific subtype of congenital hypothyroidism: thyroid dyshormonogenesis due to an iodide organification defect. The most common phenotype(More)
The human placenta is prerequisite for the development of gestational hypertensive diseases like early-onset preeclampsia (PE) and Hemolysis, Elevated Liver enzymes and Low platelets (HELLP) syndrome. Both syndromes are associated with extensive maternal and perinatal mortality, and morbidity with life long consequences. We aimed to investigate differences(More)
