A 30 year-old man was admitted to our hospital with a chief complaint of left flank pain. Computed tomography revealed a retroperitoneal tumor. Levels of lactic dehydrogenase, human beta-chorionic gonadotropin, alpha-fetoprotein, DUPAN-2 and carbohydrate antigen 19-9 were elevated. No abnormal
The secretion of human chorionic gonadotropin and its subunits was examined by a heterologous hCG/hCG-beta radioimmunoassay and homologous radioimmunoassays of the alpha- and beta-subunit in patients with nonseminomatous testicular germ cell tumors. Of 53 patients, 32 (60%) had elevated levels of
BACKGROUND
Hyperglycosylated human chorionic gonadotropin (hCG-h) contains larger and more complex carbohydrate chains than regular human chorionic gonadotropin (hCG). hCG-h is thought to be the major form of hCG produced by testicular cancers and it has been suggested to play a key role in tumor
We recently purified a 200 kD peanut agglutinin-binding glycoprotein from the embryonal carcinoma cell line HT-E (833K) that is expressed selectively in nonseminomatous germ cell tumors. We now further characterize gp200 using Western blot analysis to compare normal and malignant testicular germ
BACKGROUND
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder affecting adrenal steroid synthesis. In this study, the authors aim to evaluate the impact of CAH due to 21-hydroxylase deficiency on final height (FH), bone health, cardiometabolic risk, fertility, neurocognition and
Human chorionic gonadotropin (hCG) is a glycoprotein composed of 2 dissimilar subunits, alpha and beta, joined non-covalently. This hormone is not only heterogeneous in peptide structure but also in combination of subunits and in the structure of carbohydrate side chains. Common hCG-related
Human sera were previously shown to possess antibodies capable of recognizing purified retrovirus envelope glycoproteins. In an extension of earlier studies we investigated sera from various groups of patients for an immune reaction against purified glycoprotein of the baboon endogenous virus BaEV.
Human chorionic gonadotropin (hCG) is a polypeptide hormone studied as far as 1912, but researchers has no complete knowledge concerning its biological function. Since 1970' it is known that hCG can be found not only in the urine and serum of pregnant, but in choriocarcinoma and testicular cancer
OBJECTIVE
Hyperglycosylated human chorionic gonadotropin (hCG-H) is a carbohydrate variant of hCG with double-sized oligosaccharide side chains. While hCG-H is produced exclusively by stem cytotrophoblast cells in gestational choriocarcinoma, by pregnancy cytotrophoblast at implantation and by the
Glycosphingolipids (GSLs) are neoplastic and normal/cancer stem cell markers and GSL/cholesterol-containing membrane rafts are increased in cancer cell plasma membranes. We define a novel means by which cancer cells can restrict tumor-associated GSL immunoreactivity. The GSL-cholesterol complex
