The crystal structure of the β subunit of luteinizing hormone and a model for the intact hormone
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

Various carboxyl-terminal peptides of hCG-β were prepared from the corresponding blocked peptides by TFA treatment followed by hydrogenation. The prepared peptides were tested for inhibitory action on the binding between 125I-hCG and the antiserum against the carboxyl-terminal portion of hCG-β.

Pulmonary Metastatic Choriocarcinoma in a Patient with Ectopic Pregnancy [PDF]
Gestational trophoblastic tumor (GTT) most commonly follows a molar pregnancy. In fact, it can occur following gestational events such as induced or spontaneous abortion, ectopic pregnancy, and term pregnancy.

Stimulation of hCG protein and mRNA in first trimester villous cytotrophoblast cells in vitro by glycodelin A [PDF]
Aim: Human chorionic gonadotropin (hCG) is produced by fetal trophoblast cells and secreted into maternal circulation mainly in the first trimester of pregnancy.

Platelet-derived factors impair placental chorionic gonadotropin beta-subunit synthesis
During histiotrophic nutrition of the embryo, maternal platelets may be the first circulating maternal cells that find their way into the placental intervillous space through narrow intertrophoblastic gaps within the plugs of spiral arteries.

Localization of human chorionic gonadotropin beta subunit transcripts in ovarian cancer tissue.
Recent studies demonstrated that besides placenta and malignant trophoblastic tumors, hCG and especially its beta-subunit is secreted by a varieties of tumors of different origin.

Beta-HCG secretion by a pulmonary pleomorphic carcinoma: A case report
Ectopic secretion of beta-subunit of human chorionic gonadotropin (β-HCG) in pulmonary pleomorphic carcinoma is remarkably rare. Such unusual ectopic hormone production by lung cancer may be initially misinterpreted as extragonadal choriocarcinoma or ...

Sex differences in the pituitary TGFβ1 system: the role of TGFβ1 in prolactinoma development [PDF]
Prolactinomas are the most frequent functioning pituitary adenomas, and sex differences in tumor size, behavior and incidence have been described. These differences have been associated with earlier diagnosis in woman, as well as with serum estradiol ...
