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.

4-Methylumbelliferone induces oxidative stress-driven metabolic vulnerability and disrupts glycosylation in glioblastoma cells

This study demonstrates that 4-Methylumbelliferone (4MU) exerts antitumor effects in glioblastoma cells by inducing early oxidative stress that depletes NAD⁺, disrupts N-glycosylation, and triggers compensatory metabolic rewiring, thereby revealing a novel mechanism for targeting metabolic vulnerabilities in this aggressive brain tumor.

Molecular evidence of thermal stress in two massive coral species in a remote reef system in the southwestern Gulf of Mexico during an extreme marine heatwave

This study demonstrates that two massive coral species in a remote southwestern Gulf of Mexico reef system exhibited sustained molecular stress responses, indicated by progressively elevated HSP70 expression, during the extreme 2023–2025 marine heatwaves, revealing species-specific physiological strategies and the approach of thermotolerant corals to their functional limits under recurring thermal stress.
