Arginine Metabolic Disruption Impairs Hair Regeneration via ROS‐Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia

open access: yesAdvanced Science, EarlyView.
Arginine deficiency accelerates androgenetic alopecia. Serum metabolome shows reduced circulating arginine, while local metabolic disruption depletes follicular reserves, triggering reactive oxygen species (ROS) accumulation and mTOR suppression that induce hair miniaturization.

The Gut Resistome Atlas in Preterm Infants Enables Prediction of Necrotizing Enterocolitis Onset

open access: yesAdvanced Science, EarlyView.
The gut resistome of preterm infants and its clinical relevance remain poorly understood. This study performs in‐depth integrative analyses of 5,684 gut metagenomes from preterm infants, uncovering distinct features that diverge from term infants. Notably, the gut resistome of preterm infants converges 9 days before necrotizing enterocolitis onset ...

ADAR1 as a Placental Innate Immune Rheostat Sustaining the Homeostatic Balance of Intrinsic Interferon Response at the Maternal‐Fetal Interface

open access: yesAdvanced Science, EarlyView.
This study reveals that ADAR1, an RNA‐editing enzyme, fine‐tunes immune responses in the placenta by preventing the accumulation of immunogenic double‐stranded RNAs (dsRNAs) from interferon‐stimulated genes. The loss of ADAR1 in the placenta leads to excessive interferon signaling restricted to the junctional zone, disrupting placental development and ...

NADPH Oxidase Inhibition Promotes Brain Resilience by Attenuating Tauopathy and Neuroinflammation in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
CRB‐2131, as a novel Nox inhibitor, suppresses brain oxidation, tauopathy, and neuro‐inflammation, thereby preventing death of mature neurons and promoting regeneration of immature neurons. Ultimately, this fosters a resilient brain and protects cognition.

EETs Reduction Contributes to Granulosa Cell Senescence and Endometriosis‐Associated Infertility via the PI3K/AKT/mTOR Signaling Pathway

open access: yesAdvanced Science, EarlyView.
1) 14, 15‐EET levels were decreased in ovarian granulosa cells, follicular fluid, peritoneal fluid from endometriosis patients. 2) EETs reduction in endometriosis follicular fluid aggravated granulosa cell senescence. 3) ROS reduced 14, 15‐EET levels by upregulating EPHX2 through a mechanism involving histone methylation modification.
