Hyperglycosylated hCG.
Hyperglycosylated hCG (hCG-H) is a glycosylation variant of the hormone hCG. Here we review all that is known about this independently functioning molecule. As discussed, it is a very different molecule to the hormone hCG. First, hCG-H is produced by cytotrophoblast cells while regular hCG is made in syncytiotrophoblast cell. Second, it is an autocrine acting directly on the cells which produce...
متن کاملHyperglycosylated hCG drives malignancy in cancer cases
Purpose: Trophoblastic cancers (Choriocarcinoma, testicular and ovarian germ cell malignancies) secrete hyperglycosylated hCG and non-trophoblastic cancers secrete hyperglycosylated hCG free βsubunit.Both are structural variants of hCG independent to the hormone hCG. They are autocrines acting on a transforming growth factor β-II (TGF-β-II), receptor not acting on the hormone receptor. Here the...
متن کاملhCG and hyperglycosylated hCG in the establishment and evolution of hemochorial placentation.
The evolution of regular chorionic gonadotropin (CG) and hyperglycosylated CG are linked with the evolution of hemochorial placentation in primates. Recent research with humans shows that regular CG promotes spiral artery angiogenesis and hyperglycosylated CG controls invasion by implanting trophoblast cells. It is inferred that the evolution of regular CG and hyperglycosylated CG in early simi...
متن کاملHuman chorionic gonadotropin (hCG) and hyperglycosylated hCG, seven semi-independent critical molecules: A review
hCG exists in two analogous structures, as typified by the hormone hCG which binds an LH/hCG hormone receptor and the TGFß receptor binding autocrine hyperglycosylated hCG. Both share a common α-subunit and ß-subunit amino acid sequence. From the common hormone hCG and autocrine hyperglycosylated hCG structures there are seven common hCG variants with wildly varying hormone hCG or autocrine hyp...
متن کاملBiological functions of hCG and hCG-related molecules
BACKGROUND hCG is a term referring to 4 independent molecules, each produced by separate cells and each having completely separate functions. These are hCG produced by villous syncytiotrophoblast cells, hyperglycosylated hCG produced by cytotrophoblast cells, free beta-subunit made by multiple primary non-trophoblastic malignancies, and pituitary hCG made by the gonadotrope cells of the anterio...
