Extracellular matrices (ECMs) play a crucial role in the onset and progression of tumors by providing structural support and promoting the proliferation and metastases of tumor cells. Current therapeutic approaches targeting tumor ECMs focus on two main strategies: Inhibiting matrix degradation to prevent metastases and facilitating matrix degradation to enhance the penetration of drugs and immune cells. However, these strategies may lead to unintended consequences, such as tumor growth promotion, drug resistance, and side effects like fibrotic changes in healthy tissues. Biomaterials have made significant progress in fabricating artificial ECMs for tumor therapy by inducing biomineralization, fibrogenesis, or gelation. This perspective explores the fundamental concepts, benefits, and challenges of each technique. Additionally, future improvements and research directions in artificial ECMs are discussed, highlighting their potential to advance tumor therapy.

Objectives: Juvenile dermatomyositis (JDM) is a heterogeneous autoimmune condition needing targeted treatment approaches and improved understanding of molecular mechanisms driving clinical phenotypes. We utilised exploratory proteomics from a longitudinal North American cohort of patients with new-onset JDM to identify biological pathways at disease onset and follow-up, tissue-specific disease activity, and myositis-specific autoantibody (MSA) status.
Methods: We measured 3072 plasma proteins (Olink panel) in 56 patients with JDM within 12 weeks of starting treatment (from the Childhood Arthritis and Rheumatology Research Alliance Registry and 3 additional sites) and 8 paediatric controls.

Neutrophil extracellular trap (NET) formation, or NETosis, is a key innate immune response that contributes to cardiovascular diseases, including vascular inflammation, atherosclerosis, and thrombosis. In the cardiovascular system, neutrophils encounter mechanical cues such as shear stress, matrix stiffness, and cyclic stretch that influence their activation and NET release. This review examines emerging evidence linking altered mechanotransduction to dysregulated NETosis in vascular aging and cardiovascular pathology.

Objective: To evaluate whether pretreatment strategies targeting the extracellular matrix (ECM), such as DNase I and low-frequency ultrasound, enhance the efficacy of successive antimicrobial photodynamic therapy (aPDT) against Candida albicans biofilms and to assess the effects on biofilm components.
Methods: Forty-eight-hour C. albicans (ATCC 90028) biofilms were treated under four conditions: (I) aPDT [Photodithazine (PDZ) (25 mg/L) for 20 min + Light-Emitting Diode (LED) (660 nm, 18 J/cm²)], (II) DNase+aPDT [5 min with 20 U/mL DNase I before aPDT], (III) sonication+aPDT [7 W, 170-190 J before aPDT], (IV) Dn+So+aPDT.

Osteosarcoma (OS), the most prevalent primary bone malignancy in adolescents, is characterized by aggressive progression and early metastasis. However, the epigenetic drivers of its metastatic heterogeneity remain poorly understood. Herein, we integrated bulk DNA methylation profiling and single-cell RNA sequencing (scRNA-seq) to elucidate the epigenetic mechanisms driving OS metastatic heterogeneity.

Oxygen plays a critical regulatory role in tissue repair and regeneration. However, in the microenvironment of tissues with vascular damage, hypoxia is commonly present. This not only suppresses cell proliferation and differentiation but also delays angiogenesis and extracellular matrix reconstruction, ultimately hindering the tissue regeneration process.
