Exploring the mechanisms of mutual influence between lactylation and macrophage polarization in the context of disease

Clinical and Translational Medicine
Background Lactylation, a post‐translational alteration facilitated by lactic acidderived lactyl‐CoA, has emerged as an epigenetic regulator that alters gene expression in macrophages. Emerging data situates lactylation at the nexus of metabolic flux and

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Unraveling the role of LDHA and VEGFA in oxidative stress: A pathway to therapeutic interventions in cerebral aneurysms [PDF]

Cerebral aneurysms (CA) are critical conditions often associated with oxidative stress in vascular endothelial cells (VECs). The enzyme lactate dehydrogenase A (LDHA) plays a crucial role in glycolysis and lactate metabolism, processes implicated in the ...

Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

Advanced Science, EarlyView.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...

TrxR2 Lactylation Facilitates Mitochondrial Protection and Endothelial Ferroptosis Resistance in Diabetic Cardiomyopathy

Advanced Science, EarlyView.
TrxR2 deletion in diabetic mice suppresses TUFM‐AMPK‐FUNDC1‐dependent mitophagy in endothelial cells, resulting in SCP2 upregulation and mitochondrial translocation of ACSL4. Mitochondrial ACSL4 promotes mitochondrial eicosanoid biosynthesis and ferroptosis, thereby aggravating cardiac microvascular injury and diabetic cardiomyopathy.

m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

Advanced Science, EarlyView.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

Lactylation Enhances the Activity of Lactate Dehydrogenase A and Promotes the Chemoresistance to Cisplatin Through Facilitating DNA Nonhomologous End Junction in Lung Adenocarcinoma

Advanced Science
Lactylation is a novel post‐translational modification closely related to the glycolytic process, but the regulatory mechanisms between lactylation and glycolysis are far from being elucidated.
