Focal Adhesion Kinase (FAK) Regulates Insulin-stimulated Glycogen Synthesis in Hepatocytes [PDF]

Journal of Biological Chemistry, 2002
Experimental data support a role for FAK, an important component of the integrin signaling pathway, in insulin action. To test the hypothesis that FAK plays a regulatory role in hepatic insulin action, we overexpressed wild type (WT), a kinase inactive (KR), or a COOH-terminal focal adhesion targeting (FAT) sequence-truncated mutant of FAK in HepG2 ...

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

Advanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Biomaterials for modulating cellular responses of endogenous tendon stem/progenitor cells: A promising avenue for tendon regeneration

BMEMat, EarlyView.
This review comprehensively summarizes emerging biomaterial‐based strategies and underlying mechanisms for modulating endogenous tendon stem/progenitor cells (TSPCs). It offers the most recent insights into TSPC physiology and potential applications of tissue engineering and regenerative medicine in tendons.

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 ...

Cytoskeleton–Membrane Uncoupling in Duchenne Muscular Dystrophy: Implications for Newborn Screening and Early Protection

Cytoskeleton, EarlyView.
ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.

Focal adhesion proteins confer smooth muscle anoikis resistance and protection against aortic aneurysm and dissection

JCI Insight
Thoracic aortic aneurysm and dissection (TAAD) involves a progressive dilation of the aortic wall associated with degradation of the extracellular matrix (ECM), cystic medial degeneration, smooth muscle cell (SMC) dysfunction, and rarefaction.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Dynamic conformational changes in the FERM domain of FAK are involved in focal-adhesion behavior during cell spreading and motility. [PDF]

, 2009
Focal adhesion kinase (FAK) controls cellular adhesion and motility processes by its tight link to integrin- and extracellular-matrix-mediated signaling.

Integrin α9 Suppresses Hepatocellular Carcinoma Metastasis by Rho GTPase Signaling

Journal of Immunology Research, 2018
Integrin subunit alpha 9 (ITGA9) mediates cell-cell and cell-matrix adhesion, cell migration, and invasion through binding different kinds of extracellular matrix (ECM) components.
