Serum levels of hCG and its free subunits were measured in patients with partial and complete hydatidiform moles and in women with normal 10-week pregnancies. whereas complete moles had higher levels of percent-free beta-hCG than partial moles (2.4 versus 1.0; P less than or equal to .005), partial moles had higher levels of percent-free alpha-hCG than complete moles (0.85 versus 0.17; P less than or equal to .005). Normal 10-week pregnancies had lower levels of both percent-free beta-hCG and percent-free alpha-hCG than partial moles (0.40 versus 1.0, P less than or equal to .005 and 0.27 versus 0.85, P less than or equal to .005, respectively). Percent-free beta-hCG and beta-hCG levels did not distinguish which patients with complete mole were more likely to develop persistent post-molar tumor. The trophoblastic cells in complete and partial moles differ significantly in the manner in which they secrete the free subunits of hCG.

D006063 Chorionic Gonadotropin A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D006828 Hydatidiform Mole Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.

D015292 Glycoprotein Hormones, alpha Subunit The alpha chain of pituitary glycoprotein hormones (THYROTROPIN; FOLLICLE STIMULATING HORMONE; LUTEINIZING HORMONE) and the placental CHORIONIC GONADOTROPIN. Within a species, the alpha subunits of these four hormones are identical; the distinct functional characteristics of these glycoprotein hormones are determined by the unique beta subunits. Both subunits, the non-covalently bound heterodimers, are required for full biologic activity.

D018997 Chorionic Gonadotropin, beta Subunit, Human The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
