Placenta‐derived extracellular vesicles: Signal messengers shuttling across the maternal‐fetal barrier

Interdisciplinary Medicine, Volume 4, Issue 2, March 2026.
In normal pregnancy, PEVs help maintain maternal–fetal immune tolerance while enabling controlled immune activation, promote endothelial migration, and support trophoblast invasion and syncytialization, strengthening antimicrobial defense. In pregnancy‐related disorders, dysregulated PEV signaling may drive endothelial dysfunction and hypertension, BBB

Beta-HCG Secretion by a Pulmonary Choriocarcinoma in a Male Patient

Case Reports in Oncological Medicine
Background. Paraneoplastic secretion of beta-subunit of human chorionic gonadotropin (β-HCG) in pulmonary carcinoma is rare. Case Presentation. A 65-year-old man presented with bilateral gynaecomastia with abnormally high levels of β-hCG and elevated ...

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Domain-dependent protein folding is indicated by the intracellular kinetics of disulfide bond formation of human chorionic gonadotropin beta subunit.

Journal of Biological Chemistry, 1992
We have measured the intracellular rates of formation of the six disulfide bonds in the human chorionic gonadotropin beta subunit (hCG-beta) to determine whether the folding pathway of this molecule can be described by a simple sequential model.

Ectopic Pregnancy In Previously Infertile Women Subsequent Pregnancy Outcome After Laparoscopic Management [PDF]

Al Ameen Journal of Medical Sciences, 2009
Ectopic tubal pregnancy (ETP) is a major event in a woman's reproductive life particularly if it happens after treatment of infertility. It complicates infertility treatment and must be recognized early to simplify the treatment strategy, which must ...

Human Chorionic Gonadotropin .BETA.-Subunit Affects the Folding and Glycosylation of .ALPHA.-Cys Mutants.

Endocrine Journal, 2000
Human chorionic gonadotropin (hCG) is a member of a family of heterodimeric glycoprotein hormones that contain a common alpha-subunit but differ in their hormone-specific beta-subunits. Both subunits have five and six disulfide bonds, respectively, which consist of cystine knot structure.

Efficacy of Hormone-Toxin Fusion Protein in Cell Culture [PDF]

, 2015
Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) are members of the gonadotropin family and are vital for fertility in animals. Both LH and hCG bind to the luteinizing hormone receptor (LHR), found only in gonadal cells.
