Nrf2 Drives Epigenetic Reprogramming and Acts as the Master Regulator of KLF4 Expression and Activity in Arsenic‐Induced Transformation

open access: yesAdvanced Science, EarlyView.
Nrf2 isn't just a protector—it's a driver of cancer stemness. The study uncovers how arsenic‐activated Nrf2 directly upregulates KLF4, a key pluripotency factor, fueling oncogenic reprogramming. Through enhancer activation and self‐reinforcing loop, Nrf2 and KLF4 co‐opt gene networks linked to epithelial‐to‐mesenchymal transition and tumor growth ...

A thermodynamical model for rainfall-triggered volcanic dome collapse [PDF]

open access: yes, 2004
Dome-forming volcanic eruptions typically involve the slow extrusion of viscous lava onto a steep-sided volcano punctuated by collapse and the generation of hazardous pyroclastic flows.

Microfilament‐Myosin II Regulates the Differentiation of Multinucleated Cysts into Oocytes and Influences Oocyte Developmental Potential in Mice

open access: yesAdvanced Science, EarlyView.
In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

open access: yesAdvanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

Restoring Histone Acetylation Accelerates Diabetic Wound Repair by Improving the Spatiotemporal Dynamics of Macrophages

open access: yesAdvanced Science, EarlyView.
Butyrate—via epigenetic modulation of the histone core—rebalance dysregulated macrophage function and promotes wound healing under persisting hostile conditions of diabetic mice. Additionally, butyrate harmonizes macrophage interactions with keratinocytes and fibroblasts as well as breaks the vicious cycle of inflammation in chronic wounds by restoring

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

open access: yesAdvanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

open access: yesAdvanced Science, EarlyView.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Single‐Cell Dissection of the Biological Function and Molecular Features Underlying the Micropeptide LSMEM1 in Kidney

open access: yesAdvanced Science, EarlyView.
LSMEM1, an evolutionarily conserved micropeptide with extreme hydrophobicity (aliphatic index═113) and dynamic amphiphilicity (GRAVY═0.017), features a strong α‐helical transmembrane anchor (residues 64‐86). Single‐cell analysis reveals its critical role in renal lipid homeostasis.

Homocysteine Exacerbates Pulmonary Fibrosis via Orchestrating Syntaxin 17 Homocysteinylation of Alveolar Type II Cells

open access: yesAdvanced Science, EarlyView.
The study identifies elevated homocysteine (Hcy) levels in idiopathic pulmonary fibrosis patients' samples, with alveolar type 2 cells as the primary site of Hcy metabolism. Methionine synthase reductase downregulation in these cells exacerbates fibrosis, while folate administration reduces Hcy levels and alleviates fibrosis.
