Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

NFE2L2 and SLC25A39 drive cuproptosis resistance through GSH metabolism

Scientific Reports
Cuproptosis is a recently discovered form of regulated cell death triggered by mitochondrial copper accumulation and proteotoxic stress. Here, we provide the first evidence that glutathione (GSH), a major non-protein thiol in cells, acts as a cuproptosis

Early onset senescence occurs when fibroblasts lack the glutamate–cysteine ligase modifier subunit [PDF]

Free Radical Biology and Medicine, 2009
Cellular senescence is the irreversible entry of cells into growth arrest. Senescence of primary cells in culture has long been used as an in vitro model for aging. Glutamate-cysteine ligase (GCL) controls the synthetic rate of the important cellular antioxidant glutathione (GSH).

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

Advanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Lactylation Reprogramming in the Bone Infection Microenvironment Identifies PGK1 K361 as a Potential Therapeutic Target for Osteogenic Dysfunction

Advanced Science, EarlyView.
Staphylococcus aureus (S. aureus) infection creates a high‐lactate microenvironment, promoting p300‐mediated lactylation of PGK1 at lysine 361 (K361). Lactylated PGK1 translocates to the mitochondrial outer membrane and interacts with VDAC3. This interaction triggers FtMt downregulation, iron accumulation, and excessive PINK1/Parkin‐mediated mitophagy,

Overexpression of mitofusin 2 ameliorates inflammation and oxidative stress in lipopolysaccharide‐induced mastitis model by regulating phosphofurin acidic cluster sorting protein 2

Animal Models and Experimental Medicine, EarlyView.
The interaction between mitofusin 2 (MFN2) and phosphofurin acidic cluster sorting protein 2 regulates the formation of mitochondria‐associated endoplasmic reticulum membranes (MAM). Overexpression of MFN2 can promote the formation of MAMs and inhibit inflammation and oxidative stress response in mammary epithelial cells.

Acute toxicity of arsenic and oxidative stress responses in the embryonic development of the common South American toad Rhinella arenarum [PDF]

, 2015
Arsenic (As), a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01mg/L and 15mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.
