Hcg beta subunit
WebMeasurement of human chorionic gonadotropin (hCG) is used as an adjunct in the diagnosis of central nervous system (CNS) metastases or recurrence of tumor in patients with germ cell tumors. Quantitation of the hCG in cerebrospinal fluid (CSF) can be important in guiding treatment and monitoring response to treatment of these tumors. The β-subunit of hCG gonadotropin (beta-hCG) contains 145 amino acids, encoded by six highly homologous genes that are arranged in tandem and inverted pairs on chromosome 19q13.3 - CGB (1, 2, 3, 5, 7, 8). It is known that CGB7 has a sequence slightly different from that of the others. Visualizza altro Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually … Visualizza altro Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. Visualizza altro Naturally, it is produced in the human placenta by the syncytiotrophoblast. Like any other gonadotropins, it can be extracted … Visualizza altro Blood or urine tests measure hCG. These can be pregnancy tests. hCG-positive can indicate an implanted blastocyst and mammalian embryogenesis or can be detected for a … Visualizza altro Human chorionic gonadotropin interacts with the LHCG receptor of the ovary and promotes the maintenance of the corpus luteum for the maternal recognition of pregnancy at the beginning of pregnancy. This allows the corpus luteum to secrete the hormone Visualizza altro Three major forms of hCG are produced by humans, with each having distinct physiological roles. These include regular hCG, hyperglycosylated hCG, and the free beta-subunit of hCG. Degradation products of hCG have also been detected, including … Visualizza altro Tumor marker Human chorionic gonadotropin can be used as a tumor marker, as its β subunit is secreted by some cancers including seminoma, choriocarcinoma, germ cell tumors, hydatidiform mole, teratoma with elements of Visualizza altro

Web9 nov 2024 · Human chorionic gonadotropin (hCG) is a hormone, made up of an alpha and beta subunit, that is produced by the placenta and normally is only measurable during pregnancy. Some abnormal tissues, tumors, and cancers, however, may also produce hCG, making the hCG test useful as a tumor marker.

WebThe CG beta subunit contains a carboxy-terminal extension (CTP) with four serine O-linked oligosaccharides, which is important for the long half-life of hCG. A clinical problem of FSH is its relatively short half-life in circulation. Fusing CTP to the FSH beta coding sequence increased the in vivo potency of the resulting FSH dimer over three-fold.
