A Biomarker‐Driven Ovary–Endometrium Organ‐on‐a‐Chip Mimicking 3D Multicellular Complexity and Menstrual Cyclicity for Predicting Reproductive Toxicity

Advanced Science, EarlyView.
We present a dual‐organ, biomarker‐integrated ovaryendometrium organ‐on‐a‐chip that recapitulates 3D tissue complexity, menstrual cycle dynamics, and hormonal crosstalk. This platform enables real‐time, cell‐typespecific fluorescent readouts of reproductive toxicity using ANGPTL4 and SERPINB2 as early‐response reporters.

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

Advanced Science, EarlyView.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

PFOS Disrupts Oocyte Maturation and Early Embryonic Development via Ovarian FOXK1 O‐GlcNAcylation in Mice

Advanced Science, EarlyView.
Perfluorooctane sulfonate (PFOS) exposure disrupts oocyte maturation and early embryonic development. This study elucidates the mechanism by which enhanced O‐GlcNAcylation of FOXK1 underlies the PFOS‐induced reduction of progesterone levels in granulosa cells and the disturbance of follicular microenvironment.

Pharmacokinetics, pharmacodynamics and safety of vutiglabridin after multiple oral administrations in healthy female and obese subjects

British Journal of Clinical Pharmacology, EarlyView.
Aims Vutiglabridin (HSG4112) is a novel drug under clinical development for antiobesity treatment. This study aimed to evaluate the pharmacokinetics (PKs) and safety of vutiglabridin after multiple oral administrations in healthy Korean female and obese subjects and explore short‐term pharmacodynamic (PD) responses.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Bioengineered Isoflavone–Probiotic Functional Foods for Sustainable Modulation of Metabolic and Reproductive Health in PCOS

Food Bioengineering, EarlyView.
Synergistic isoflavone‐probiotic action modulated metabolic, microbial and ovarian pathway ABSTRACT Polycystic ovary syndrome (PCOS) is a prevalent metabolic–endocrine disorder characterized by insulin resistance, hyperandrogenism, chronic inflammation, oxidative stress, and ovarian dysfunction, with growing evidence implicating gut microbiota ...

Different dendritic domains of the GnRH neuron underlie the pulse and surge modes of GnRH secretion in female mice

eLife, 2020
The gonadotropin-releasing hormone (GnRH) neurons exhibit pulse and surge modes of activity to control fertility. They also exhibit an unusual bipolar morphology comprised of a classical soma-proximal dendritic zone and an elongated secretory process ...

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...
