CXCL4-Induced PBMCs Modulate Vascular Extracellular Matrix via Wnt5a-Dependent Matrix Metalloproteinase-7 and Calcifying Extracellular Vesicle Release

[Arteriosclerosis Thrombosis and Vascular Biology] The authors introduced a novel mechanism driving monocyte-mediated ECM remodeling in procalcific inflammatory responses through Wnt5a-CaMKII–activated secretion of MMP7+S100A8+ calcifying extracellular vesicle by CXCL4-induced proinflammatory monocytes.

Traction Force and Mechanosensitivity Mediate Species-Specific Implantation Patterns in Human and Mouse Embryos

[Cell Death & Disease] Researchers demonstrated that embryos apply forces remodeling the matrix with species-specific displacement amplitudes and distinct radial patterns: principal displacement directions for mouse embryos, expanding on the surface, while human embryos insert in the matrix, generating multiple traction foci.

Seeing Deep to Map Cell-Biomaterial Interactions via Whole Mount Light Sheet Imaging and Automated Analytics in Decellularized Extracellular Matrix Models

[Biomaterials Science] Scientists optimized optical imaging and analysis protocols to overcome imaging challenges and enable quantitative assessments of decellularized ECM models, demonstrating a use case in engineered in vitro cancer microenvironments.

P4HA1 Mediates YAP Hydroxylation and Accelerates Collagen Synthesis in Temozolomide-Resistant Glioblastoma

[Chinese Medical Journal] Investigators revealed that temozolomide exposure significantly elevated collagen type I expression in both glioblastoma patients and murine models.

Glutaminase Inhibition Ameliorates Cancer-Associated Fibroblast Lipid Support of Pancreatic Cancer Cell Growth

[Cancer & Metabolism] Researchers emphasized the importance of glutamine metabolism inhibition in suppressing tumor growth and disrupting cancer-associated fibroblast-mediated crosstalk.

Matrix Stiffness Drives Alterations in Aldehyde Metabolism, Inducing DNA Damage, and Transformation

[Scientific Reports] Scientists showed that ECM stiffness induces changes in mammary epithelial cell metabolism which drive DNA damage.

The Function of Metalloproteinases in Pathophysiology of Inflammatory Bowel Disease and Colon Cancer

[Journal of Leukocyte Biology] The authors review the potential utilization of matrix metalloproteinases (MMPs) as biomarkers for inflammatory bowel disease (IBD)/colorectal cancer (CRC) diagnosis, prognosis and treatment response. MMPs remain central to both IBD and CRC biology and present both challenges and opportunities for therapeutic intervention and disease monitoring.

State to Purchase Medications for Cystic Fibrosis Patients under Rare Disease Treatment Program

[Gerogian Public Broadcaster] Georgia's Rare Disease Treatment Programme is being expanded. According to the Ministry of Health, the state will purchase inhalation preparations, antibiotics, vitamins and other medications for patients with cystic fibrosis.

Emerging Implications of N6-Methyladenosine in Prostate Cancer Progression and Treatment

[Cell Death Discovery] The authors review the emerging roles of N6-methyladenosine (m6A) regulators, including readers, writers, and erasers, and the downstream m6A-modified mRNA and noncoding RNA in prostate cancer.

EGFR-STAT3 Activation Provides a Therapeutic Rationale for Targeting Aggressive ETV1-Positive Prostate Cancer

[Molecular Oncology] Using prostate cancer cells overexpressing ETS variant 1 (ETV1) or ETS related gene, researchers unveiled a positive feedback loop between ETV1 and epidermal growth factor receptor (EGFR), with STAT3 acting as a downstream effector of ETV1–EGFR signaling.

Dual-Functional Anti-hPSMAEC Domain Nanocapsules for Targeted Inhibition of Prostate Tumor Growth

[Apoptosis] Investigators synthesized advanced nanocapsules embedded with indocyanine green and conjugated with the Anti-hPSMAEC domain to improve specificity towards prostate cancer cells.

Epigenetic De-Repression of PROX1 Promotes Neuroendocrine Prostate Cancer Progression

[Cancer Research] Scientists functionally characterized the role of prospero-homeobox 1 (PROX1) in neuroendocrine prostate cancer (NEPC). An unbiased CRISPR screen in two NEPC patient-derived organoid models demonstrated high cellular dependency for PROX1.
