The Role of Post-Translational Modifications in Necroptosis

Biomolecules
Necroptosis, a distinct form of regulated necrosis implicated in various human pathologies, is orchestrated through sophisticated signaling pathways. During this process, cells undergoing necroptosis exhibit characteristic necrotic morphology and provoke

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

Advanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Targeting Macrophage STING O‐GlcNAcylation via Small‐Molecule Allosteric Modulation for Psoriasis Therapy

Advanced Science, EarlyView.
Paeoniflorin allosterically targets the STING cyclic dinucleotide‐binding domain, stabilizes an inactive open conformation, and disrupts STING–OGT interaction to reduce Thr229 O‐GlcNAcylation and downstream signaling. This mechanism restrains myeloid STING activation, alleviates psoriasis‐like inflammation, and is supported by analyses of patient ...

Investigation of raw and thermally treated peanut major allergen post- translational modifications (PTMs) [PDF]

, 2019
Introduction. Peanut allergy affects a large portion of world population causing reactions ranging from mild to severe. Major peanut allergen IgE epitopes are well characterized but little is known about their post-translational modifications (PTM) and how they are affected by thermal treatment.

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

Proximity‐Induced Protein Deglycosylation by Endogenous O‐GlcNAcase

Angewandte Chemie, EarlyView.
Bifunctional molecules recruit endogenous O‑GlcNAcase to target proteins, enabling selective de‑O‑GlcNAcylation in living cells without perturbing global O‑GlcNAc homeostasis. This work developed a programmable chemical strategy for targeted O‑GlcNAc editing and framework for functional enzymatic recruitment via optimization of competitive enzyme ...

Systematic analysis of the effects of splicing on the diversity of post-translational modifications in protein isoforms using PTM-POSE

Cell Systems
Abstract Post-translational modifications (PTMs) and splicing are important regulatory processes for controlling protein function and activity. Despite examples of interplay between alternative splicing and cell signaling in literature, there have been few detailed analyses of the impacts of alternative splicing on ...

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

Advanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

Distinct PXR Inverse Agonism Mechanisms Rely on Differential Ligand‐induced Co‐Regulator Recruitment

Angewandte Chemie, EarlyView.
Pregnane X receptor (PXR) antagonism is ligand‐encoded: SPA70 recruits corepressors NCoR1 (nuclear receptor corepressor 1)/SMRT (silencing mediator for retinoid and thyroid‐hormone receptors) while binding coactivators, and is modulated by retinoid X receptor alpha (RXRα); MI891 causes cytoplasmic retention and corepressor‐dependent repression ...
