Hyperglycosylated hCG, hCGβ and Hyperglycosylated hCGβ: interchangeable cancer promoters

Abstract

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.
