The effect of local photoionization on the galaxy properties and the circumgalactic medium in simulations of Milky Way-sized galaxies [PDF]

open access: yesarXiv
In this study, we investigate the impact of local stellar radiation in cosmological zoom simulations of the formation of Milky Way-sized galaxies. We include the radiation field as an additional feedback component that is computed alongside gravity with a tree code in an optically thin approximation.

AKT1 Phosphorylates FDX1 to Promote Cuproptosis Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study demonstrates that copper activates the AKT signaling pathway, which inhibits ferredoxin‐1 (FDX1), a key regulator of cuproptosis. AKT1‐mediated FDX1 phosphorylation not only abrogates FDX1‐induced cuproptosis and aerobic respiration but also promotes glycolysis.

PCSK9 Promotes the Malignancy of Triple‐negative Breast Cancer Cells by Reducing Cholesterol Levels at the Plasma Membrane to Activate EGFR and HER3

open access: yesAdvanced Science, EarlyView.
By decreasing cholesterol and lipid raft levels in the plasma membrane, proprotein convertase subtilisin/kexin type 9 (PCSK9) boosts human epidermal growth factor receptor 1 and 3 (EGFR and HER3) activation, driving tumor growth and metastasis in triple‐negative breast cancer (TNBC).

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

open access: yesAdvanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...

Polyplex Nanomicelle‐Mediated Pgc‐1α4 mRNA Delivery Via Hydrodynamic Limb Vein Injection Enhances Damage Resistance in Duchenne Muscular Dystrophy Mice

open access: yesAdvanced Science, EarlyView.
This study presents a novel approach for treating Duchenne muscular dystrophy using mRNA encoding PGC‐1α4. Nanomicelle‐delivered Pgc‐1α4 mRNA enhances muscle damage resistance and mitochondrial activity in dystrophic muscles. This study demonstrates the potential of mRNA therapy for neuromuscular diseases like Duchenne muscular dystrophy and highlights

Osteosarcoma Cell‐Derived Migrasomes Promote Macrophage M2 Polarization to Aggravate Osteosarcoma Proliferation and Metastasis

open access: yesAdvanced Science, EarlyView.
Migrasomes are newly discovered organelles in migrating cells. This study finds that osteosarcoma cell‐derived migrasomes promote the tumor‐promoting phenotype of macrophages and further aggravate osteosarcoma malignant progression via milk fat globule‐EGF factor 8.

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Antigen‐Targeting Inserted Nanomicelles Guide Pre‐Existing Immunity to Kill Head and Neck Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a tumor‐targeted nanomicelle platform (preS1‐pHLIP) that exploits pre‐existing antiviral immunity to combat heterogeneous cancers. By delivering viral antigens to label tumors as virus‐like targets, the nanomicelles activate antiviral B and T cells, triggering in situ tumor lysis.

HNF3α Targets Nckap1l and Promotes Renal Fibrosis Following Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Hepatocyte Nuclear Factor 3 alpha (HNF3α) is significantly upregulated in renal tubular epithelial cells of CKD patients and fibrotic mice. Deletion of HNF3α mitigates IRI‐induced renal fibrosis, while overexpression worsens it. HNF3α directly regulates NCK‐associated protein 1‐like (Nckap1l), whose overexpression exacerbates fibrosis.
