Pharmacogenetics of follicle‐stimulating hormone action in the male

Andrology, Volume 14, Issue 4, Page 1064-1072, May 2026.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

Kinetics of folding and assembly of the human chorionic gonadotropin beta subunit in transfected Chinese hamster ovary cells.

Journal of Biological Chemistry, 1992
We have employed Chinese hamster ovary (CHO) cell lines transfected with either the wild type human chorionic gonadotropin beta (hCG-beta) gene alone (CHO beta cells) or in conjunction with the gene expressing the alpha subunit (CHO alpha,beta cells) to ...

Advances in the Use of Recombinant Gonadotropins for Reproductive Biotechnologies in Ruminants: A Review

Reproduction in Domestic Animals, Volume 61, Issue 5, May 2026.
ABSTRACT Recombinant gonadotropins, particularly recombinant follicle‐stimulating hormone (rFSH) and recombinant equine chorionic gonadotropin (reCG), have emerged as viable alternatives to traditional animal‐derived hormones in reproductive biotechnologies. This review aims to provide an updated and comprehensive overview of recombinant gonadotropins,

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, Volume 20, Issue 4, Page 1022-1040, April 2026.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

Recognition of the Beta-subunit of human chorionic gonadotropin and sub-determinants by target tissue receptors [PDF]

Biochemical Journal, 1978
The beta-subunit of human chorionic gonadotropin, purified immunochemically to eliminate undissociated human chorionic gonadotropin, induced testosterone production by mouse Leydig cells at concentrations 400-fold higher than human chorionic gonadotropin. Steroidogenesis was also stimulated by a synthetic fragment of the beta-subunit of human chorionic

Evolution of placental function in mammals:the molecular basis of gas and nutrient transfer, hormone secretion, and immune responses [PDF]

, 2012
Placenta has a wide range of functions. Some are supported by novel genes that have evolved following gene duplication events while others require acquisition of gene expression by the trophoblast.

Clinical Use of Combined First‐Trimester Screening Test for Aneuploidy in A Low‐Income Setting: Retrospective Study

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Although combined first trimester screening is effective at detecting fetal chromosomal anomalies which are trisomy 21, 18 and 13, there is scarce data on its practice and practice in low‐income countries. This study presents data on clinical use of combined first trimester prenatal screening tests among pregnant women in a Sub ...
