Lyssavirus Nucleoprotein Induces GPAT4‐Mediated CYB5R1 Depalmitoylation to Suppress Ferroptosis and Promote Viral Replication

Advanced Science, EarlyView.
Lipid metabolism plays a vital role in viral infections. Here, we reveal that the lyssavirus N protein regulates GPAT4 to induce lipid droplet biogenesis, restricting CYB5R1 palmitoylation and reducing ferroptosis susceptibility to ultimately promote viral replication.

Development of Identification for Post-Translational Modifications in Histones by Mass Spectrometry Based Proteomics

, 2010
In eukaryotic cells, chromosomal DNA is packaged into a compact structure, chromatin, with the help of four core histones. The fundamental repeating unit of chromatin is the nucleosome, which contains an octamer of core histones, around 147 base pairs of

Fumarate Hydratase Lactylation Exacerbates Traumatic Brain Injury Pathology via Mitochondrial Dysfunction and Neuroinflammation

Advanced Science, EarlyView.
Tian et al. reveal that FH K112 lactylation is elevated after TBI, leading to fumarate accumulation, mitochondrial damage, mtDNA release and amplified neuroinflammation. AARS2 and SIRT3 act as the “writer” and “eraser” for FH K112 lactylation. The peptide Pep‐K112 targeting this site alleviates brain injury, highlighting a potential therapeutic target.

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

Advanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

SAV1 in Cooperation With FKBP52 Participates in Implantation

Advanced Science, EarlyView.
The MST‐SAV1 complex modulates FKBP52 phosphorylation to fine‐tune PR activity, ensuring timely uterine transition to receptivity under estrogen signaling for implantation. Stromal SAV1 scaffolds MST1/2‐mediated FKBP52 phosphorylation via noncanonical Hippo to promote PR activity.

Lactylation‐Driven PROS1‐TYRO3‐CARF Signaling Promotes Therapy‐Induced Senescence Escape and Radioresistance in Meningioma

Advanced Science, EarlyView.
A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.
