Elimination of luteinizing hormone cross-reactive epitopes from human chorionic gonadotropin

open access: yes, 2002
The beta-chain of human chorionic gonadotropin (hCG) has been shown to have efficacy in clinical trials when used as a contraceptive vaccine. This hormone is a heterodimer, the alpha-chain being shared with the other members of the glycoprotein hormone ...

Organization and sequence of the gene encoding the human acrosin-trypsin inhibitor (HUSI-II) [PDF]

open access: yes, 1993
A complete cDNA encoding the acrosin-trypsin inhibitor, HUSI-II, was used as a probe to isolate genomic clones from a human placenta library. Three clones which cover the entire HUSI-II gene were isolated and characterized.

Ectopic production of the beta-subunit of human chorionic gonadotropin in osteosarcoma.

open access: yesArchives of pathology & laboratory medicine, 1989
Production of human chorionic gonadotropin by sarcomas is an uncommon phenomenon that has rarely been documented. A case of a 26-year-old woman with osteosarcoma of the left fibula and high levels of serum beta-human chorionic gonadotropin (beta-HCG) is described. Immunoperoxidase staining showed numerous tumor cells reacting with the beta-HCG antibody.

Ability of human chorionic gonadotropin beta-subunit to inhibit the steroidogenic response to lutropin

open access: yes, 1979
Ability of the beta-subunit of human chorionic gonadotropin to inhibit the response to lutropin (luteinizing hormone, LH) was tested in the immature rat ovarian system and pregnant-mare-serum-gonadotropin-primed rat ovarian system with progesterone ...

Human Chorionic Gonadotropin .BETA.-Subunit Affects the Folding and Glycosylation of .ALPHA.-Cys Mutants.

open access: yesEndocrine Journal, 2000
Human chorionic gonadotropin (hCG) is a member of a family of heterodimeric glycoprotein hormones that contain a common alpha-subunit but differ in their hormone-specific beta-subunits. Both subunits have five and six disulfide bonds, respectively, which consist of cystine knot structure.

Analysis of the Relationship between CGB5 155G/C Polymorphism and in vitro Fertilization-embryo Transfer Outcome (IVF-ET) in the Iranian Population [PDF]

open access: yesMajallah-i dānishgāh-i ̒ulūm-i pizishkī-i Arāk, 2018
Background: Successful pregnancy depends on the ability of the embryo to achieve appropriate extent of trophoblastic proliferation and invasion into maternal endometrium as well as, once implanted, to induce its own blood supply.
