Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

open access: yesAdvanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.

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

open access: yesAdvanced 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.

Genetic Evidence Supporting a Role for Brain Region Volume and Functional Network Alterations in Major Depression

open access: yesAdvanced Science, EarlyView.
Genome‐wide analyses indicate that reduced ventral diencephalon and thalamus volumes, along with decreased functional connectivity within the triple network (DMN/CEN/SN), are uniquely associated with the risk of major depression (MD) onset, compared to other similar severe psychiatric disorders.

Local p‐ and n‐Type Doping of an Oxide Semiconductor via Electric‐Field‐Driven Defect Migration

open access: yesAdvanced Science, EarlyView.
Local acceptor and donor doping is achieved in a semiconducting oxide by controlled splitting of oxygen interstitial‐vacancy pairs under applied d.c. voltage. The separated oxygen defects are demonstrated to form interstitial‐rich (p‐type) and vacancy‐rich (n‐type) regions, comparable to dipolar npn‐junctions, enabling transient functionalization ...

Intermediate Filament Protein BFSP2 Controls Spindle Formation via HSC70‐Mediated Stabilization of CLTC During Oocyte meiosis

open access: yesAdvanced Science, EarlyView.
Meiosis is a specialized form of cell division that has different regulation and mechanisms with mitosis in numerous aspects. Particularly, meiosis I is unique and occurs only in germ cells to separate homologous chromosomes. Thus, determining how this unusual chromosome segregation behavior is established is central to understanding germ cell ...

The genetic association between bipolar disorder and dementia: a qualitative review

open access: yesFrontiers in Psychiatry
Bipolar disorder is a chronic disorder characterized by fluctuations in mood state and energy and recurrent episodes of mania/hypomania and depression. Bipolar disorder may be regarded as a neuro-progressive disorder in which repeated mood episodes may ...
