β1-integrin regulates astrocytic differentiation.

, 2014
A. NSCs were infected with retrovirus expressing GFP alone (ctrl pCLE) orβ1-integrinlacking the cytoplasmic domain (β1-integrin ΔC), cultured for 7 days on PDL-laminin and immunostained for GFAP (red) and DAPI (blue). Scale bar = 20 µm. B.

Viscoelastic hydrogel potentiates cancer cell stemness and drug resistance through Piezo1‐dependent mechanotransduction

BMEMat, EarlyView.
The effects of matrix dynamics on cancer progression remain unclear. Herein, we fabricated a tunable dynamic hydrogel via reversible host–guest crosslinking and demonstrated that high matrix dynamics activate Piezo1 and its downstream PI3K/AKT and Wnt/β‐catenin signaling pathways, thereby enhancing cancer spheroid assembly, elevating cancer stemness ...

Enhanced fibroblast contraction of 3D collagen lattices and integrin expression by TGF-β1 and -β: mechanoregulatory growth factors?

, 2002
Generation of contractile forces as fibroblasts attach and migrate through collagenous substrates is a fundamental behavior, yet its regulation and consequences are obscure.

Substrate stiffness regulates cell fate and its applications in the repair of motor system: From two dimensions to three dimensions

BMEMat, EarlyView.
Substrate stiffness with different dimensions (2D and 3D) exerts a regulatory role in cellular behaviors, thereby governing cell fate decisions. Biomaterials with tunable stiffness exhibit substantial functional potential for the repair and regeneration of the motor system.

Harnessing bacterial extracellular vesicles for bone and cartilage organoids

BMEMat, EarlyView.
This review presents bacterial extracellular vesicles (BEVs) as programmable bioactive regulators for bone and cartilage organoids by delivering functional cargos that modulate skeletal remodeling. It highlights key engineering strategies and future directions to advance next‐generation organoid models for bone aging related diseases.

Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

BMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

Chemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

Unraveling the Multimodal Oncogenic Network of KITENIN: From Metabolic Reprogramming and Microenvironment Remodeling to Targeted Interventions

Cancer Nexus, EarlyView.
ABSTRACT KAI1 C‐terminal interacting tetraspanin (KITENIN) is an emerging oncogenic regulator associated with tumorigenesis, metastasis, therapeutic resistance, and poor clinical outcomes. Mechanistically, KITENIN promotes tumor cell proliferation, migration, invasion, and epithelial–mesenchymal transition (EMT) by activating oncogenic pathways ...

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.
