Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Histomorfometria e histoquímica dos ovários, tubas e útero de ratas hipotireóideas em metaestro-diestro Histomorphometry and histochemistry of the ovaries, oviduct and uterus in hypothyroid rats in the metaestrus-diestrus

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2004
A foliculogênese ovariana foi estudada em ratas adultas Wistar, hipotireóideas na fase de metaestro-diestro. O hipotireoidismo foi induzido pela administração oral e diária de propiltiouracil (1mg/animal). As ratas eutireóideas receberam placebo.

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Exclusive Breastfeeding Drives AMPK‐Dependent Thermogenic Memory in BAT and Promotes Long‐Term Metabolic Benefits in Offspring

Advanced Science, EarlyView.
Exclusive breastfeeding establishes a thermogenic memory in brown adipose tissue by activating the HIF1AN/AMPK/α‐ketoglutarate axis via milk‐derived extracellular vesicles enriched in miR‐125a‐5p. This programming preserves metabolic health, while αKG supplementation restores BAT function under mixed feeding, offering strategies to mitigate the ...
