Assignment of disulfide bonds in the beta subunit of human chorionic gonadotropin.

open access: yesJournal of Biological Chemistry, 1980
The assignment of five disulfide bonds in the alpha subunit of human chorionic gonadotropin (hCG) using partial reduction and S-[14C]carboxymethylation has been reported earlier (Mise, T., and Bahl, O. P. (1980) J. Biol. Chem. 255, 8516-8522). Employing a similar approach, we have determined the locations of six disulfide bonds in hCG-beta.

Involvement of human chorionic gonadotropin in regulating vasculogenic mimicry and hypoxia-inducible factor-1α expression in ovarian cancer cells [PDF]

open access: yes, 2016
BACKGROUND: Human chorionic gonadotropin (hCG) can play a crucial role in angiogenesis. In the present study, we focused on hCG to gain insight into its potential effects on vasculogenic mimicry (VM) in ovarian cancer cells. METHODS: Ovarian cancer OVCAR-

Human chorionic gonadotropin (hCG) concentrations during the late first trimester are associated with fetal growth in a fetal sex-specific manner [PDF]

open access: yes, 2017
Human chorionic gonadotropin (hCG) is a pregnancy-specific hormone that regulates placental development. hCG concentrations vary widely throughout gestation and differ based on fetal sex.

Beta-Subunit of Human Chorionic Gonadotropin in Malignant Lymphoma : An Immunohistochemical Study [PDF]

open access: yes, 1991
We present a rare case of a 77-year-old Japanese man with malignant lymphoma associated with production of beta-subunit of human chorionic gonadotropin in the cytoplasms of lymphoma cells in the lymph nodes.

Evolution of placental function in mammals:the molecular basis of gas and nutrient transfer, hormone secretion, and immune responses [PDF]

open access: yes, 2012
Placenta has a wide range of functions. Some are supported by novel genes that have evolved following gene duplication events while others require acquisition of gene expression by the trophoblast.

SDS-PAGE Electrophoretic Property of Human Chorionic Gonadotropin (hCG) and its β-subunit [PDF]

open access: yesInternational Journal of Biological Sciences, 2005
The microheterogeneity property of hCG with regards to its sialic acid contents resulted in variable mobility of the glycoprotein in SDS-PAGE. The intact hCG molecule is composed of two dissimilar subunits, namely alpha- and beta-subunits. The identification of hCG bands in SDS-PAGE was accomplished by the immunoblotting experiment, whereby the ...
