Published: February 2012

Introduction: Several groups are researching cancers, and showing that hCGβ is a promoter of cancer growth and malignancy. Recent research shows that some hCGβ is present as Hyperglycosylated hCGβ. Other groups studied Hyperglycosylated hCG as a promoter of choriocarcinoma and germ cell malignancies. The question therefore arises, are Hyperglycosylated hCG, hCGβ and Hyperglycosylated hCGβ interrelated or interchangable promoters of cancer?

Methods: The actions of Hyperglycosylated hCGβ, hCGβ and Hyperglycosylated hCG are investigated in 7 cell lines, Jar and JEG-3 choriocarcinoma cell lines, NTERA germ cell cancer line, SCaBER and T24 bladder epithelial carcinoma lines, KLE and Hec-1-a endometrial adenocarcinoma and epithelial carcinoma cell lines. Actions of promoters on cell growth are investigated.

Results: The actions of Hyperglycosylated hCG, hCGβ and Hyperglycosylated hCGβ appear to be interchangeable in all cell lines investigated.

Discussion: All hCG-related cancer promoters seem interrelated, working through a similar mechanism, antagonism of apoptosis through know receptors such as TGFβ receptors in all cancers studied.

Background: Per- and polyfluoroalkyl substances (PFAS) are widely detected in pregnant women and associated with adverse outcomes related to impaired placental function. Human chorionic gonadotropin (hCG) is a dimeric glycoprotein hormone that can indicate placental toxicity.

Objectives: Our aim was to quantify the association of serum PFAS with placental hCG, measured as an intact molecule (hCG), as free alpha-() and beta-subunits (), and as a hyperglycosylated form (h-hCG), and evaluate effect measure modification by social determinants and by fetal sex.

Human chorionic gonadotropin (hCG) is produced by the placenta and its roles have been studied for over a century, being the first known pregnancy-related protein. Although its main role is to stimulate the production of progesterone by corpus luteal cells, hCG does not represent just one biologically active molecule, but a group of at least five variants, produced by different cells and each with different functions. The hyperglycosylated variant of hCG (H-hCG) plays a key role in trophoblast invasion, placental development and fetal growth.

Forskolin Induces Endocrine Disturbance in Human JEG-3 Placental Cells.

Forskolin, used in folk medicine since ancient times, is now available as a dietary supplement, with an indication as a fat burner and appetite suppressant. However, the safety of forskolin is poorly documented especially for pregnant women. The question that we raised is what about the safety of forskolin in pregnant women? As the placenta, an endocrine organ, is the key organ of pregnancy, we evaluated the in vitro placental toxicity of forskolin.

Human chorionic gonadotropin (hCG) has four major isoforms: classical hCG, hyperglycosylated hCG, free β subunit, and sulphated hCG. Classical hCG is the first molecule synthesized by the embryo. Its RNA is transcribed as early as the eight-cell stage and the blastocyst produces the protein before its implantation.
