Loss of LCN2 Function Ameliorates Glucocorticoid‐Induced Muscle Atrophy via Remodeling the Extracellular Matrix

Advanced Science, EarlyView.
Glucocorticoids transcriptionally activate LCN2 expression via GR nuclear translocation. Secreted LCN2 binds MMP9 to degrade skeletal muscle ECM collagen, blocks integrin‐mediated mechanotransduction, bidirectionally disrupts muscle protein homeostasis, and reveals a novel target for steroid‐induced muscle atrophy.

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

DYNAMICS OF FIBROSIS MARKERS ON THE BACKGROUND OF TB/HIV CO-INFECTION TREATMENT

Buletinul Academiei de Ştiinţe a Moldovei: Ştiinţe Medicale
TB/HIV co - infection remains one of the biggest medical problems in Ukraine and the world. In tuberculosis, MTB stimulates immunocompetent cells to produce MMP-9, which destroys collagen fibers.

SynNotch Receptors for Visualizing Immunoreceptor Force Transmission and Downstream Signaling In Vivo

Advanced Science, EarlyView.
A mechanically activated SynNotch reporter platform enables detection of force transmission through receptors as they mediate immune cell interactions. Targeting CD40 on B cells and TCR on T cells records force‐induced reporter activation across 2D coculture, 3D organoid, and implanted in mice, which also reveal force‐amplification of immune receptor ...

Dual‐Gene Edited Extracellular Vesicles Remodel the Redox Homeostasis to Inhibit Ferroptosis in Intervertebral Disc Degeneration

Advanced Science, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is driven by ferroptosis of nucleus pulposus cells (NPCs) as a core pathological mechanism. Nucleus pulposus progenitor cells (NPPCs), exhibiting stem cell‐like properties, yield extracellular vesicles (PEVs) with high affinity for NPCs and enable targeted phenotypic regulation.

Autophagy Orchestrates Anti‐Tumor Immunity to Enhance Chemosensitivity via the FBXW2/C/EBPβ/TIMP‐2 Axis in Colorectal Cancer

Advanced Science, EarlyView.
Chemotherapy leverages tumor‐cell autophagy to reshape the colorectal cancer immune microenvironment. Autophagy degrades FBXW2 to promote C/EBPβ‐mediated TIMP‐2 transcription and MMP‐9 suppression, driving intra‐tumoral CD8+ T‐cell infiltration. Targeting MMP‐2/9 or restoring TIMP‐2 overcomes chemo‐resistance in autophagy‐deficient tumors. ABSTRACT The

ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

Advanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

Serum TIMP-1 concentrations are associated with cancer incidence and cancer-related mortality in a population-based cohort

Scientific Reports
The tumor microenvironment is regulated by matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs); however, their utility as cancer biomarkers remains unclear.
