Fibrothecoma in a Virgo Intacta Adolescent with Elevated Levels of CA 125 and B-hCG: A Case Report
Children, 2022 Ovarian fibromas are benign tumors that consist of spindle cells in bundles or storiformly arranged with collagen fibers in the stroma. Thecomas resemble theca interna ovarian cells, and there is lipid material in their cytoplasm.

Ectopic Production of the Isolated Beta Subunit of Human Chorionic Gonadotropin [PDF]
Journal of Clinical Investigation, 1973 A material similar to the beta subunit of human chorionic gonadotropin (hCG-beta) was detected in serum (300 ng/ml) and tumor extract from a 75-yr-old man with pancreatic adenosquamous carcinoma. This material was indistinguishable from hCG-beta in three different types of radioimmunoassay that displayed widely varying reactions with glycoprotein ...

Origin and Occurrence of Human Chorionic Gonadotropin β-Subunit Core Fragment [PDF]
Molecular Endocrinology, 1988 Human chorionic gonadotropin (hCG) beta-subunit core fragment (beta-fragment) is present in the urine of pregnant individuals as well as those with trophoblast disease and certain other cancers at concentrations 0.8 (early pregnancy) to 7 (second trimester pregnancy)-fold greater than that of hCG.

Variants of human chorionic gonadotropin from pregnant women and tumor patients recognized by monoclonal antibodies [PDF]
, 1993 In biological fluids, hCG and its free alpha- (hCG alpha) and beta-subunits (hCG beta), occur in multiple forms. These various forms differ at the molecular level primarily in glycosylation, but also differ in protein backbone modifications corresponding

The crystal structure of the β subunit of luteinizing hormone and a model for the intact hormone
Current Research in Structural Biology, 2019 The β subunit of bovine luteinizing hormone (LH) was crystallized and its structure solved to 3.15 Å resolution by molecular replacement using human chorionic gonadotropin (hCG) β subunit as search model. The asymmetric unit contains two copies of the β
