Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

Advanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...

Selenoprotein H Functions as a PPARα Coactivator to Link Selenium Homeostasis to Hepatic Lipid Metabolism and Protect against Steatohepatitis

Advanced Science, EarlyView.
Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

Advanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...
