NFS1 Regulates IDH2 to Attenuate Abdominal Aortic Aneurysms via Interacting With SP2

Advanced Science, Volume 13, Issue 14, 9 March 2026.
The loss of NFS1 leads to its reduced binding with the transcription factor SP2, resulting in decreased expression of the downstream gene Idh2. This causes a shift in energy supply toward glycolysis in VSMCs, ultimately contributing to the occurrence and progression of AAA.

Mechanism and structural dynamics of sulfur transfer during de novo [2Fe-2S] cluster assembly on ISCU2

Nature Communications
Maturation of iron-sulfur proteins in eukaryotes is initiated in mitochondria by the core iron-sulfur cluster assembly (ISC) complex, consisting of the cysteine desulfurase sub-complex NFS1-ISD11-ACP1, the scaffold protein ISCU2, the electron donor ...

The Infra-Red Spectrum and Molecular Configuration of Hydrogen Persulfide [PDF]

, 1949
The infra‐red spectrum of hydrogen persulfide has been investigated in the region 1.5 to 15μ, and vibrational assignments have been made. The perpendicular band at 2μ has been studied under high resolution and a value for one of the rotational constants ...

Physiologically relevant reconstitution of iron-sulfur cluster biosynthesis uncovers persulfide-processing functions of ferredoxin-2 and frataxin [PDF]

, 2019
International audienceIron-sulfur (Fe-S) clusters are essential protein cofactors whose biosynthetic defects lead to severe diseases among which is Friedreich's ataxia caused by impaired expression of frataxin (FXN).

Iron‐Based Materials for Advanced Lithium/Sodium‐Ion Batteries

ChemSusChem, Volume 19, Issue 4, 25 February 2026.
This Review examines iron‐based anode materials for lithium‐ and sodium‐ion batteries, emphasizing how phase chemistry (sulfides, oxides, and metal–organic framework (MOF)‐derived compounds), multiscale structural engineering, and interface regulation collectively address volume expansion, conductivity limitations, and cycling instability, while ...

Rapid and selective generation of H2S within mitochondria protects against cardiac ischemia-reperfusion injury

Redox Biology, 2022
Mitochondria-targeted H2S donors are thought to protect against acute ischemia-reperfusion (IR) injury by releasing H2S that decreases oxidative damage.
