AAV-mediated delivery of leptin but not adiponectin improves metabolic health in a mouse model of congenital generalised lipodystrophy

This study demonstrates that AAV-mediated leptin gene therapy significantly improves metabolic health in a mouse model of congenital generalised lipodystrophy, whereas adiponectin delivery yields no beneficial effects, highlighting leptin's potential as a long-term therapeutic alternative to daily injections.

Dynamic proteomic profiling reveals protein-specific regulation of synthesis rates underpinning the divergent adaptation of human muscle to endurance and resistance training

This study utilizes dynamic proteomic profiling to demonstrate that human skeletal muscle adapts to endurance and resistance training through distinct, protein-specific regulation of synthesis rates within shared subcellular locations, rather than solely through changes in bulk protein fractions.

Hepatic HIF2α modulates extra-hepatic disease-associated phenotypes during metabolic dysfunction-associated steatotic liver disease

In a mouse model of metabolic dysfunction-associated steatotic liver disease (MASLD), hepatocyte-specific deletion of HIF2α failed to protect against liver disease progression and instead exacerbated extra-hepatic complications, including myocardial lipid accumulation, cardiac dysfunction, and loss of lean body mass.

Colonic metabolomic and transcriptomic alterations in a mouse model of metabolic syndrome

This study demonstrates that metabolic syndrome induces significant metabolic and microbial alterations in the colon without inflammation, identifying conserved dysregulated pathways in both mouse models and humans that implicate colonic dysfunction as a potential driver of disease progression and a target for future therapies.

Effects of muscle mass on muscle force predictions in human movement

This study demonstrates that while incorporating muscle mass into Hill-type models significantly improves force predictions for larger-than-human muscles or high-cadence movements, the difference between mass-enhanced and traditional massless models remains negligible (<1%) for standard human-sized locomotion.

Empagliflozin targets a renal neuro-epithelial-immune axis in heart failure

This study demonstrates that empagliflozin confers renoprotection in heart failure by suppressing renal sympathetic hyperactivity and disrupting a maladaptive neuro-epithelial-immune axis, which shifts renal macrophages toward a reparative phenotype and reduces tubular inflammation independently of the renin-angiotensin system.

Pattern of Circulating Mesenchymal Stromal Cells and Hematopoietic Progenitor and Stem Cells in the Peripheral Blood of Trauma Patients with and without Hemorrhagic Shock

This prospective study of trauma patients reveals that while hemorrhagic shock triggers an initial surge in circulating stem and progenitor cells and cytokines, their subsequent sharp decline and persistent early elevation in non-survivors correlate with worse outcomes, suggesting that serial profiling of these biomarkers could serve as a prognostic tool and identify a therapeutic window for regenerative interventions.

Estrogen-Nitric Oxide Signaling Modulates Mitochondrial Dynamics and Endothelial Lipid Handling to Protect Against Early Atherosclerosis

This study demonstrates that estrogen and nitric oxide signaling protect against early atherosclerosis through distinct yet complementary mechanisms by reducing endothelial oxLDL uptake via different pathways, preserving mitochondrial homeostasis, and modulating inflammatory responses to limit lesion formation.
