Clinical Info

Identification human chorionic gonadotropin expression in neoplasms
Human chorionic gonadotropin (hCG) is produced by the syncytiotrophoblasts of the placenta and has the same biologic properties as pituitary luteinizing hormone (LH). hCG stimulates androgen and progesterone production in women and helps maintain the corpus luteum of pregnancy. hCG is a heterodimeric hormone of 36kD with subunits designated alpha and beta. Many neoplasms including choriocarcinomas and adenocarcinomas may express hCG.
