Thyrotropic Action of Human Chorionic Gonadotropin

Thyroid, 1995
Hyperthyroidism or increased thyroid function has been reported in many patients with trophoblastic tumors. In these cases, greatly increased human chorionic gonadotropin (hCG) levels and suppressed TSH levels suggest that hCG has thyrotropic activity.

Carboxypeptidase Digestion of Human Chorionic Gonadotropin

Endocrine Research Communications, 1977
Native human chorionic gonadotropin (hCG) was resistant to carboxypeptidase digestion even in the presence of urea. Isolated alpha subunit of the hormone (hCG-alpha), though unreactive to enzyme treatment in the absence of denaturant, released up to four amino acid residues from the C-terminus on incubation with a mixture of carboxypeptidases A and B ...

Nature of the Subunits of Human Chorionic Gonadotropin

Endocrinology, 1971
Subunits of human chorionic gonadotropin have been isolated from carboxymethyl- HCG by preparative poly aery lamide electrophoresis, by chromatography on Sephadex G-25, and from native HCG by chromatography on DEAE-Sephadex A-25. HCG-α subunit has been estimated to have a Stokes’ radius of 23.3 A by gel filtration and a molecular weight by SDSgel ...

Human chorionic gonadotropin and the fetal allograft

American Journal of Obstetrics and Gynecology, 1972
Abstract With the use of the mixed-lymphocyte-culture reaction, it is shown that human chorionic gonadotropins (HCG) can inhibit this reaction only at concentrations above those normally present throughout most of pregnancy and of the order of that found in maternal serum at the time of the HCG peak at the end of the first trimester. The significance

Human chorionic gonadotropin in the ectopic gestation

International Journal of Gynecology & Obstetrics, 1985
AbstractThe ectopic pregnancy is a relatively common condition in the south African black patients. The beta‐specific subunit radioimmunoassay for human chorionic gonadotrophin (HCG) was utilized in procuring information in our series of 30 patients. Levels of the hormone were significantly lower when compared to normal gestation of similar duration ...

Immunology of Human Chorionic Gonadotropin (HCG)

1967
Publisher Summary This chapter discusses the immunology of human chrionic gonadotropin (HCG). It also reviews the immunology of HCG, examples of various disciplines involved in hormone research where immunological methods are employed. These include the characterization of HCG preparations, the detection of contaminating proteins, quantitative ...

Human chorionic gonadotropin hormone is antiviral

Medical Hypotheses, 1996
Although it is well known that human chorionic gonadotropin maintains the corpus luteum's ability to secrete estrogen and progesterone, I believe that it serves yet another important function. Early evidence suggests that human chorionic gonadotropin is a broad-spectrum antiviral/immune potentiator.

Human chorionic gonadotropin and associated molecules

Expert Review of Molecular Diagnostics, 2009
When considering human chorionic gonadotropin (hCG) and hCG tests, it is important to realize that it is not a single biological molecule. The regular form of hCG produced by differentiated syncytotrophoblast cells (regular hCG) is a hormone made with the primary function of maintaining the myometrial and decidual spiral arteries and the vascular ...
