Maternal diet-induced excess adiposity programs multisystem vulnerability that is unmasked by postnatal infection challenge

This study demonstrates that maternal high-fat diet-induced excess adiposity programs latent, sex-specific vulnerabilities in the immune, intestinal, and metabolic systems of offspring, which are unmasked as multisystem dysfunction following a postnatal *Streptococcus pneumoniae* infection.

Coordination-Sphere Perturbations Partition Catalytic Bias Control in a Thermostable [FeFe]-Hydrogenase

This study reveals that the catalytic bias of the thermostable [FeFe]-hydrogenase Tk HydA2 is governed by a distributed regulation model where distinct perturbations in the first- and second-coordination spheres of its iron-sulfur clusters synergistically modulate kinetic, electrostatic, and redox-relay effects to fine-tune the enzyme's reversible H2 interconversion.

METTL3-IGF2BP3 m⁶A axis drives mutant huntingtin stability and neurodegeneration in Huntington’s disease

This study identifies the METTL3-IGF2BP3 m⁶A axis as a critical driver of mutant huntingtin accumulation and neurodegeneration in Huntington's disease, demonstrating that targeting this epitranscriptomic pathway selectively reduces mHTT toxicity and inflammation in affected cells.

PTPRN hypermethylation-driven transcriptional repression defines a conserved regulatory axis in early- and adult-onset schizophrenia

This study identifies a conserved epigenetic-transcriptional axis in schizophrenia characterized by PTPRN hypermethylation-driven repression, which links early neurodevelopmental perturbations in adolescent-derived cells to persistent molecular alterations in the adult brain.

A CGM-Derived Late-Phase Glycemic Response Phenotype During Fasted Moderate-Intensity Running

This study identifies a late-phase glycemic response phenotype (∆G) during fasted moderate-intensity running as a reliable metric only when averaged across repeated trials, revealing that while it correlates with skeletal muscle index in recreational exercisers, this association is confounded by sex and exercise intensity, indicating ∆G is not a direct biomarker of muscle mass.

Identification and validation of key genes of Xiaozhengtongluo formula in the treatment of diabetic nephropathy by Mendelian randomization

This study identifies and validates APOD, IGFBP3, and LPL as key therapeutic targets of the Xiaozhengtongluo formula in treating diabetic nephropathy by integrating Mendelian randomization, network analysis, and experimental verification to elucidate their causal roles and underlying molecular mechanisms.

ORP5 preserves mitochondrial function and suppresses apoptosis through inhibition of VDAC1 oligomerization in myocardial infarction

This study demonstrates that ORP5 protects against myocardial infarction-induced cardiac injury by translocating to mitochondria-associated membranes to directly interact with and inhibit VDAC1 oligomerization, thereby preserving mitochondrial function and suppressing cardiomyocyte apoptosis.
