NDST3‐Induced Epigenetic Reprogramming Reverses Neurodegeneration in Parkinson's Disease
Advanced Science, EarlyView.NDST3‐mediated epigenetic reprogramming revitalizes neuronal circuits in the substantia nigra and striatum to halt dopaminergic neuron degeneration and restore motor function in Parkinson's disease models. This strategy promotes neuronal maintenance and functional recovery, highlighting NDST3's therapeutic potential in neurodegenerative disorders ...

Advanced Science, EarlyView.PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton
Advanced Science, EarlyView.This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.
