Anti-HIV effect of beta subunit of human chorionic gonadotropin (βhCG) in vitro

Immunology Letters, 1995
Human chorionic gonadotropin (hCG)--a pregnancy-associated immunomodulating hormone--has been recently shown in vitro to suppress reverse transcriptase activity in chronically HIV-infected lymphocytes and monocytes and to block viral transmission resulting from cell-cell contact between virus-carrying lymphocytes and placental trophoblasts.

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

LOCALIZATION, DISTRIBUTION AND SECRETION OF β-SUBUNIT OF HUMAN CHORIONIC GONADOTROPIN IN NORMAL HUMAN CHORIONIC TISSUE

ACTA HISTOCHEMICA ET CYTOCHEMICA, 1979
Glycoproteins, including human chorionic gonadotropin (hCG), though not of pituitary origin, consist of two subunits, namely α- and β-subunit. Wide attention has been paid to the activities of β-subunit of those hormones not only biologically but immunologically, in regard to clinical interests.

Parallel Liquid Biopsy Analysis of miR‐371a‐3p and Cell‐Free DNA in an Unselected Cohort of Patients With Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background Despite robust data showing strong potential to improve diagnosis and disease monitoring in testicular germ cell tumors (TGCTs), miR‐371a‐3p testing has not yet been implemented in routine clinical practice. Cell‐free DNA (cfDNA) represents another promising liquid biopsy biomarker that may provide complementary molecular ...

Comparison of four different analyzers for prenatal trisomy 21 risk

Advances in Laboratory Medicine
Various analyzers are available for measuring first-trimester combined screening for trisomy 21 (T21) serum biomarkers (free-beta subunit of the human chorionic gonadotropin (β-hCG) and the pregnancy-associated plasma protein A (PAPP-A)).

A new contingent screening strategy increased detection rate of trisomy 21 in the first trimester

BMC Pregnancy and Childbirth, 2023
Background Although the traditional contingent screening strategy is effective, there are still undetected low-risk trisomy 21. This study aims to define appropriate cut-off values of serum biochemical markers at low-risk and develop a strategy for ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

The combined screening test in the first trimester of pregnancy and preeclampsia [PDF]

Scripta Medica, 2015
Introduction: The combined screening test in the first trimester of pregnancy and determination of biochemical markers, pregnancy-associated plasma protein-A (PAPP-A) and free beta subunit of human chorionic gonadotropin (free ß-hCG) were measured to ...
