The Critical Role of Enhanced OXPHOS and Mitochondrial Hyperpolarization in Simulated Microgravity‐Induced Oocyte Maturation Arrest

Advanced Science, EarlyView.
Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

LPS‐Induced Mitochondrial Damage via SLC41A1‐Mediated Magnesium Ion Efflux Leads to the Pyroptosis of Dental Stem Cells

Advanced Science, EarlyView.
Lipopolysaccharide induces upregulation of the magnesium (Mg2+) efflux transporter solute carrier family 41 member 1 in dental stem cells, leading to a decrease in intracellular Mg2+ concentration and promoting the binding of oligomycin sensitivity‐conferring protein and cyclophilinD.

Nanomaterials Trigger Functional Anti‐Tumoral Responses in Primary Human Immune Cells

Advanced Science, EarlyView.
Nanoparticles are used to improve immunomodulatory therapies, but the impact of drug‐free nanomaterials on the immune system remains unknown. Screening common biomedical nanoparticles (NPs) reveals that PLGA NPs enhanced NK cell anti‐tumoral activity and transcriptional activation in human NK and pan T cells.

Identifying Tipping Points during Healthy Brain Aging through Single‐Nucleus Transcriptomic Analysis

Advanced Science, EarlyView.
This study applies single‐nucleus transcriptomics and systems dynamics to uncover nonlinear aging patterns in healthy human brains. By introducing dynamic network biomarker theory, the authors identify a critical tipping point at ages 56–60 during aging, and highlight glial instability as a key mediator.

Internal Phase Separation in Synthetic DNA Condensates

Advanced Science, EarlyView.
The modular, programmable system of DNA nanostructures developed provides programmatic control over multiphase condensate behavior, enabling mapping onto a predictive Flory‐Huggins model. This combined experimental and theoretical framework will help address open questions in condensate biophysics and facilitate the rational design of functional ...

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...
