Evaluation of beta-subunit chorionic gonadotropin as an aid in diagnosis of trophoblastic disease.
The advent of the radioimmunoassay of Beta subunit chorionic gonadotropin (BhCG) has eliminated a major problem in following the patient with gestational trophoblastic neoplasia (GTN). Whole hCG cross reacts with luteinizing hormone (hLH) causing difficulties when GTN patient titers fall to levels coincidental with pituitary levels of hLH. The use of the Beta subunit of hCG in radioimmunoassay ...
متن کاملThe amino acid sequence of human chorionic gonadotropin. The alpha subunit and beta subunit.
The amino acid sequences of both the alpha and beta subunits of human chorionic gonadotropin have been determined. The amino acid sequence of the alpha subunit is: Ala - Asp - Val - Gln - Asp - Cys - Pro - Glu - Cys-10 - Thr - Leu - Gln - Asp - Pro - Phe - Ser - Gln-20 - Pro - Gly - Ala - Pro - Ile - Leu - Gln - Cys - Met - Gly-30 - Cys - Cys - Phe - Ser - Arg - Ala - Tyr - Pro - Thr - Pro-40 -...
متن کاملBeta-human Chorionic Gonadotropin-secreting Lung Adenocarcinoma.
Overexpression of beta-human chorionic gonadotropin (β-hCG) is frequently associated with germ cell tumours, especially choriocarcinoma. Ectopic secretion of β-hCG by non-small cell lung cancer is exceptional. We present an exceedingly rare case of pulmonary adenocarcinoma that secretes β-hCG. Our patient is a 62-year-old postmenopausal woman, a nonsmoker, who presented with a six-month history...
متن کاملQuantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles
Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...
متن کاملDetection of a glycosylated, incompletely folded form of chorionic gonadotropin beta subunit that is a precursor of hormone assembly in trophoblastic cells.
The alpha and beta subunits of human chorionic gonadotropin are secreted both as a combined, noncovalently linked dimer form as well as uncombined, free forms by human trophoblastic cells. We have utilized the cultured choriocarcinoma cell line JAR to determine what regulates the combination of the two subunits. The human chorionic gonadotropin subunits produced by JAR cells were biosynthetical...
