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

Paired versus alternate breastfeeding: Does hindmilk become foremilk?

Pregnancy
Introduction Breast milk fat content increases four‐fold from foremilk to hindmilk. Within each nursing episode, women may partially feed on both breasts (paired feeding) or nurse from one breast at a feed and the other breast at the next feed (alternate

Antimicrobial protein and Peptide concentrations and activity in human breast milk consumed by preterm infants at risk of late-onset neonatal sepsis.

PLoS ONE, 2015
ObjectiveWe investigated the levels and antimicrobial activity of antimicrobial proteins and peptides (AMPs) in breast milk consumed by preterm infants, and whether deficiencies of these factors were associated with late-onset neonatal sepsis (LOS), a ...

Computational Design and Glycoengineering of Interferon‐Lambda for Nasal Prophylaxis Against Respiratory Viruses

Advanced Science, EarlyView.
This study presents an engineered human interferon‐lambda (hIFN‐λ) as an intranasal prophylactic against respiratory viruses. By combining AI‐guided backbone redesign and glycoengineering, the authors developed a thermostable, protease‐resistant, and scalable variant with improved mucosal penetration.

YKT6 Promotes Bladder Cancer Progression by Stabilizing β‐catenin Through USP7‐Mediated Deubiquitination

Advanced Science, EarlyView.
The SNARE protein YKT6 is upregulated in bladder cancer (BLCA), correlating with poor prognosis. YKT6 promotes tumor proliferation and metastasis by activating Wnt/β‐catenin signaling. It recruits Ubiquitin‐Specific Peptidase 7 (USP7) to deubiquitinate and stabilize β‐catenin, enhancing its nuclear accumulation and driving oncogenic gene expression ...

Amphiregulin and Epiregulin Confer Radioresistance in Esophageal Squamous Cell Carcinoma Through Oxidative Phosphorylation

Advanced Science, EarlyView.
Oxidative phosphorylation (OXPHOS) activity serves as a critical metabolic determinant of radiotherapy outcomes in esophageal squamous cell carcinoma (ESCC). The CEBPB/AREG/EREG axis drives radioresistance in ESCC by reprogramming OXPHOS. AREG and EREG function as predictive biomarkers for nCRT response and prognosis of ESCC patients.

Genetic and Functional Evidence Links Germline Biallelic Inactivating Variants in WWOX to Histological Mixed‐Type Thyroid Cancer

Advanced Science, EarlyView.
The role of germline WWOX loss‐of‐function variants in oncogenesis has remained poorly characterized. This study provides the first comprehensive genetic and functional evidence that such variants promote tumorigenesis through the disruption of multiple tumor‐suppressive mechanisms.

The Association Between Maternal Dietary Intake and the Risk of Heavy Metals in Human Breast Milk in Korea

Toxics
Heavy metals (HMs) persist in the environment and enter the human body via various pathways. Once stored in adipose tissue, they can be transferred to breast milk, posing risks to infants. Moreover, maternal diet plays a key role in influencing HM levels

Midkine‐Mediated Microglia Activation after Renal Injury Promotes Cognitive Impairment Following Ischemic Renal Injury

Advanced Science, EarlyView.
The mechanism of secondary cognitive impairment following AKI. When renal ischemic injury progresses to fibrosis, renal fibroblasts and damaged tubular cells secrete MDK, which circulates through the bloodstream, crosses the damaged BBB, and accumulates in the hippocampus tissue (an area crucial for learning and memory).

Morphine Tolerance Gated through EZH2‐Mediated Suppression of Trpc5 in Spinal GABAergic Interneurons in Male Mice

Advanced Science, EarlyView.
Chronic morphine suppresses Trpc5 in spinal GABAergic interneurons via EZH2‐mediated histone modification, reducing Ca2+ influx and GABA release. TRPC5 activation enhances morphine analgesia, while EZH2 inhibition restores efficacy and reverses tolerance.
