Lactate‐H3K18la‐RPL11 Axis Drives Gemcitabine Resistance in Pancreatic Cancer by Integrating Protein Synthesis and DNA Damage Repair

open access: yesAdvanced Science, EarlyView.
A lactate‐H3K18la epigenetic axis upregulates RPL11 to drive gemcitabine resistance in pancreatic cancer. RPL11 orchestrates chemoresistance through a dual, compartmentalized role: enhancing cytoplasmic protein synthesis via EEF1A1 stabilization and promoting nuclear DNA damage repair by co‐activating PARP14, thus ensuring robust cell survival ...

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

open access: yesAdvanced 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.

Identification of Lysine Acetylation in Mycobacterium abscessus Using LC–MS/MS after Immunoprecipitation

open access: yes, 2016
Mycobacterium abscessus (MAB), which manifests in the pulmonary system, is one of the neglected causes of nontuberculous mycobacteria (NTM) infection. Treatment against MAB is difficult, characterized by its intrinsic antibiotic drug resistance.

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

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

open access: yesAdvanced 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.

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

open access: yesAdvanced 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 ...

Histone Lactylation Drives WNK1 Expression to Promote Esophageal Squamous Cell Carcinoma Progression Through Histone H3 Ser10 Phosphorylation

open access: yesAdvanced Science, EarlyView.
In brief. Yan et al. demonstrated that the excess lactate produced by the enhanced glycolysis pathway in esophageal cancer can lactylate H3K23, H3K23la can be enriched in the WNK1 promoter region to promote WNK1 expression, thereby increasing the phosphorylation of the p‐H3 Ser10 site, and p‐H3S10 can be enriched in the AKT1 promoter region to promote ...

Tip60‐Mediated USP22 Lactylation Drives Glutamine Metabolic Reprogramming via SLC25A5 in TNBC

open access: yesAdvanced Science, EarlyView.
Tip60‐mediated USP22 K134 lactylation, stabilizing SLC25A5 to enhance glutamine metabolism and α‐KG secretion. The secreted α‐KG drives GPR91‐dependent M2 macrophage polarization, promoting triple‐negative breast cancer progression. Targeting this axis synergizes with CB‐839, offering a promising therapeutic strategy for TNBC.
