CypD Dependent mPTP Opening Is Crucial for Oxidized Mitochondrial DNA Release in Ferroptosis
Advanced Science, EarlyView.Ferroptosis is driven by mitochondrial permeability transition pore (mPTP) opening, which induces mitochondrial swelling and releases oxidized mitochondrial DNA. The released mtDNA activates cGAS–STING signaling, promotes ferritinophagy, and amplifies ferroptotic cell death. Disruption of mtDNA repair sensitizes tumors to ferroptosis in vivo, revealing

Hydrogen SI and HCCI Combustion in a Direct-Injection Optical Engine [PDF]
, 2009 Hydrogen has been largely proposed as a possible alternative fuel for internal combustion engines. Its wide flammability range allows higher engine efficiency with leaner operation than conventional fuels, for both reduced toxic emissions and no CO2 ...

Advanced Science, EarlyView.Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,

Advanced Science, EarlyView.A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing
