MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

open access: yesAdvanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

open access: yesAdvanced Science, EarlyView.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, EarlyView.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

open access: yesAdvanced Science, EarlyView.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

TTNPB Promotes Human Pluripotent Stem Cell‐to‐Neural Stem Cell Transition via Modulation of Chromatin Accessibility and the S‐(5′‐adenosyl)‐L‐homocysteine/Choline Metabolic Network

open access: yesAdvanced Science, EarlyView.
A retinoic acid receptor agonist, TTNPB, drives the efficient generation of advanced neural stem cells (ANSCs) from human pluripotent stem cells. TTNPB‐centered chromatin remodeling and metabolic reprogramming, promote neuroectoderm commitment. The resulting cells show robust neural potential and functional efficacy in a rat depression model.

Natural Negative Feedback Loops Confer Indica‐Japonica Differentiation for Grain Size Homeostasis in Rice

open access: yesAdvanced Science, EarlyView.
This study reveals the genetic and molecular mechanisms controlling grain size homeostasis through fine‐tuning OsGRX8 self‐expression by two natural negative feedback loops functioning in redox‐dependent or ‐independent manners and identifies two self‐regulatory haplotypes (SRHs) for the subspecies differentiation in rice.
