Choriocarcinoma-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 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 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 کاملMeasurement of Human Chorionic Gonadotrophin (hCG) in the management of Trophoblastic disease
Human Chorionic Gonadotrophin (hCG) is mainly a product of the syncytiotropoblastic cells of the placenta although it is also secreted, in lesser quantities, by cytotrophoblastic cells and several nonplacental tissues. It is produced in gestational trophoblastic neoplasms (GTN) and maybe seen in nontrophoblastic neoplasms (Stenman, 2006). hCG is essential in pregnancy as it promotes transformat...
متن کاملHuman chorionic gonadotrophin: comparative studies of ovarian uptake in mammals.
-l. The localization of radiolabeled human chorionic gonadotrophin (~2SI-HCG) was studied in a number of commonly used mammalian animal models. 2. The ovary proved to be the target organ for ~25I-HCG in all animals studied. 3. The optimum time for the localization of HCG in the ovary varied in all the mammals extending from 1.5 to 4 hr. 4. HCG is apparently used in the target cell for only a br...
