Identification of a heterodimer-specific epitope present in human chorionic gonadotrophin (hCG) using a monoclonal antibody that can distinguish between hCG and human LH.
Human chorionic gonadotrophin (hCG) is secreted during early pregnancy and is required for implantation and maintenance of the pregnancy. Active or passive immunoneutralization of hCG results in termination of pregnancy and this forms the basis of the hCG-based female contraceptive vaccine. However, the beta subunit of hCG possesses 85% sequence homology with the first 114 amino acids of the be...
متن کاملExpression of luteinizing hormone/human chorionic gonadotrophin (LH/HCG) receptor mRNA in the human ovary.
The gonadotrophins follicle stimulating hormone (FSH) and luteinizing hormone (LH) are key hormones in the regulation of ovarian function. In the present study, the expression of LH/human chorionic gonadotrophin (HCG) receptor mRNAs in the human ovary was examined. Northern blot analysis was used to measure relative amounts of LH/HCG receptor mRNA, and in-situ hybridization was used to localize...
متن کاملChoriocarcinoma-like human chorionic gonadotrophin (HCG) and HCG bioactivity during the first trimester of pregnancy.
The objective of this study was to evaluate the distribution of choriocarcinoma-like human chorionic gonadotrophin (HCG) isoforms during first trimester pregnancy and their relationship with in-vitro HCG bioactivity. This was done by means of a retrospective analysis of patients' sera with first trimester normal intrauterine and abnormal (ectopic) pregnancies. Serum samples were obtained from 3...
متن کاملThe expression of Beta Human Chorionic Gonadotrophin (β-HCG) in human urothelial carcinoma
INTRODUCTION Studies regarding the immuno-histological expression and relevance of Beta-Human Chorionic Gonadotrophin (=-HCG) in urothelial carcinoma are few. There is also no clear cut way of predicting exactly which superficial urothelial carcinomas would subsequently recur or progress and which muscle-invasive urothelial tumours would progress. The objective of the study was to study the imm...
متن کاملInteraction of human chorionic gonadotropin (hCG) and asialo-hCG with recombinant human thyrotropin receptor.
hCG is a putative thyroid stimulator. The present studies were undertaken to examine its interaction and that of its desialylated variant asialo-hCG with recombinant human TSH (hTSH) receptor (hTSHr). To this end, we transfected a human thyroid carcinoma cell line (HTC) lacking endogenous TSHr with the full-length cDNA of the hTSHr. Unlike the wild type, the transfected cells, termed HTC-TSHr c...
