NSUN2‐Mediated m5C Modification of TGFB1 in Trophoblasts Remodels Macrophage Function to Prevent URSA

Advanced Science, EarlyView.
NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...

Electroacupuncture-induced reduction of myocardial ischemia–reperfusion injury via FTO-dependent m6A methylation modulation

Open Medicine
This study aims to investigate the potential of electroacupuncture to mitigate myocardial ischemia–reperfusion injury (MIRI) by influencing N6-methyladenosine (m6A) methylation through modulation of the fat mass and obesity-associated protein (FTO).

N6-methyladenosine (m6A) regulates signaling pathways during early embryo development

, 2022
N6-methyladenosine (m6A) is the most abundant internal modification in eukaryotic mRNA. In recent years, a slew of interesting studies had confirmed its essential role as a post-transcriptional regulator of gene expression in a wide range of biological ...

FTSJ3‐Mediated 2′‐O‐Methylation of HSPA5 mRNA Stabilizes BOP1 via SUMOylation to Drive DRP1‐Dependent Mitochondrial Fission and Fatty Acid Oxidation in Lung Squamous Cell Carcinoma

Advanced Science, EarlyView.
The RNA methyltransferase FTSJ3 drives lung squamous cell carcinoma progression by catalyzing 2′‐O‐methylation of HSPA5 mRNA, which stabilizes BOP1 through SUMOylation and activates DRP1/SREBP1‐mediated mitochondrial fission and fatty acid oxidation. Targeting this axis with liposomal siRNA potently suppresses tumor growth and metastasis ABSTRACT Lung ...

Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

Advanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

m6A mosaics

This thesis investigates new therapeutic strategies for heart disease by exploring early cardiac development. Cardiomyocytes, the heart’s contractile cells, lose their ability to repair themselves after birth, leading to permanent damage after injury.

AARS2‐SIRT5‐Driven DLD K445 Lactylation Promotes Cuproptosis Resistance in Glioblastoma Stem Cells

Advanced Science, EarlyView.
Lactylation of DLD at K445 by AARS2 suppresses PDH complex activity and reduces DLAT lipoylation, thereby conferring cuproptosis resistance in glioblastoma stem cells. SIRT5‐mediated delactylation restores PDH function and enhances cuproptosis sensitivity.

MDM2–GPX4–ferroptosis regulatory axis exerts neurotoxic effects in intracerebral hemorrhage

Neural Regeneration Research
Ferroptosis plays a key role in nerve injury in intracerebral hemorrhage and is associated with the upregulation of murine double minute 2. Investigating the mechanism underlying murine double minute 2-related ferroptosis could help identify new ...

The Cytoplasmic MicroRNA‐Production Complex Regulates MicroRNA Sorting to Extracellular Vesicles During Synaptogenesis

Advanced Science, EarlyView.
The mechanisms of microRNA cargo sorting to extracellular vesicles, important mediators of cell communication, are not fully understood. This study reveals that the microRNA‐production machinery acts as a ‘hub’ for the sorting of microRNAs to extracellular vesicles, a process regulated by dynamic organelle interactions.
