CDH1 Orchestrates Anabolic Events to Promote Cell Cycle Initiation

Advanced Science, EarlyView.
Cell proliferation requires the integration of cell cycle and anabolic signals. G1‐phase regulator CDH1 coordinates anabolism through the CDH1‐VHL‐AARS2/HIF1α axis, while CDH1‐accumulated R5P is sensed by TKTL1 to facilitate CDH1 degradation and cell cycle initiation, constituting a CDH1‐centered regulatory circuit.

Maneuvering Charge Transport via Insulating Polymer Interface for Steering Photoredox Catalysis

Advanced Science, EarlyView.
Non‐conjugated insulating polymer functions as an electron‐capturing mediator to boost interfacial charge transfer and separation, contributing to considerably enhanced photocatalytic selective organic transformation and solar CO2 conversion under visible light irradiation. Abstract Maneuvering precise and tunable charge transportation has remained the

Three‐Step Pulse Strategy Enhances Ultradilute Nitrate‐to‐Ammonia Conversion via Microenvironment and Mass Transfer Control

Advanced Science, EarlyView.
Electrochemical treatment of low‐concentration nitrate in wastewater is challenging. This study introduces a three‐step pulsed method that achieves near‐perfect efficiency in converting ultradilute nitrate to ammonia. Combined experiments and simulations reveal how pulsed strategy boost kinetics while suppressing competing reactions.

OsNRT1.1B‐OsCNGC14/16‐Ca2+‐OsNLP3 Pathway: Phosphorylation‐Mediated Maintenance of Nitrogen Homeostasis

Advanced Science, EarlyView.
OsNRT1.1B forms a membrane complex with OsCNGC14/16 that mediates nitrate‐triggered calcium influx. This calcium signal phosphorylates OsNLP3 at Ser193, accelerating its nuclear translocation and activating nitrogen‐responsive genes. The calcium‐dependent pathway complements the established ubiquitination‐mediated pathway, dynamically regulating ...
