Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

open access: yesAdvanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Mechanistic Foundations of KRAS‐Driven Tumor Ecosystems: Integrating Crosstalk among Immune, Metabolic, Microbial, and Stromal Microenvironment

open access: yesAdvanced Science, EarlyView.
KRAS mutations dynamically remodel the tumor microenvironment (TME), fostering immunosuppression, metabolic symbiosis, and stromal plasticity. This review dissects how oncogenic KRAS variants sculpt TME networks and explores actionable vulnerabilities. Emerging strategies combining KRAS inhibitors and TME‐editing approaches offer potential to dismantle

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

open access: yesAdvanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

HLA‐DR⁺ Tumor Cells Show an Association with a Distinct Immune Microenvironment and CD8⁺ T‐Cell Exhaustion in HBV‐Associated Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
This study integrates scRNA‐seq, multiplex immunofluorescence, and clinical data to identify HLA‐DR⁺tumor cells uniquely enriched in Hepatocellular carcinoma (HCC) with hepatitis B virus (HBV). These cells express MHC II, associate with PD‐L1, recruit and exhaust CD8⁺T cells, predict poor survival, and serve as potential biomarkers for immunotherapy ...

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Plasmonic Molecular Entrapment for Label‐Free Methylated DNA Detection and Machine‐Learning Assisted Quantification

open access: yesAdvanced Science, EarlyView.
Plasmonic molecular entrapment (PME) is label‐free detection and quantification method for DNA methylation. This technique provides direct hotspot site generation around target analytes, overcoming mismatch geometrical properties. The PME demonstrates superior SERS performance and quantification capability, offering promising potential for epigenetic ...
