“Activation‐Resistance Elimination” Regulation by Lanthanide/Transition Metal Ion‐Coordinated Nanostructures Intensifies Cuproptosis and Tumor Immunotherapy

Advanced Materials, EarlyView.
The lanthanide/transition metal ion coordination nanoparticles, La‐Cu@Lap/IWR‐1, with optimized coordination, have been proven to achieve remarkable results in realizing comprehensive tumor cuproptosis through efficient cuproptosis activation and multidimensional resistance elimination, thereby synchronously realizing the synergistic antitumor effects ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Defined Matrices Reveal Epithelial‐ and Mesenchymal‐Specific Responses to Stiffness and Adhesion in Human iPSC‐Derived Intestinal Organoids

Advanced Materials, EarlyView.
Defined PEG hydrogels enable human iPSC‐derived intestinal organoid culture without Matrigel. PEG‐ and Matrigel‐cultured organoids both support duodenal‐like epithelial identity, but direct comparison reveals subtle epithelial differentiation‐marker shifts and stronger mesenchymal ECM‐remodeling/integrin programs in PEG.

Beyond PI3Ks: Targeting Phosphoinositide Kinases in Disease

Nature Reviews Drug Discovery, 2023
Lipid phosphoinositides are master regulators of almost all aspects of a cell's life and death and are generated by the tightly regulated activity of phosphoinositide kinases. Although extensive efforts have focused on drugging class I phosphoinositide 3-

MAP kinase kinase kinases and innate immunity

Trends in Immunology, 2006
Toll-like receptors, which respond to invariant microbial molecules, and receptors for the proinflammatory cytokines tumour necrosis factor and interleukin-1 are crucial for initiation and regulation of innate immune responses. These receptors activate each of the major mitogen-activated protein (MAP) kinase subtypes, extracellular signal-regulated ...

MAP kinase kinase kinase, MAP kinase kinase and MAP kinase

Current Opinion in Genetics & Development, 1994
Signal transduction pathways that respond to external signals through the MAP kinase family of protein kinases are involved in diverse responses in eukaryotic cells. MAP kinases are one element in a series of kinases that serve to connect the plasma membrane with cytoplasmic and nuclear events. MAP kinases have the unusual feature that their activation

The Mnks: MAP kinase-interacting kinases (MAP kinase signal-integrating kinases)

Frontiers in Bioscience, 2008
The human MAP kinase-interacting kinases (or MAP kinase signal-integrating kinases), Mnks, comprise a group of four proteins derived from two genes (Gene symbols: MKNK1 and MKNK2) by alternative splicing. Mnk1a/b differ at their C-termini, as do Mnk2a/2b: in each case, the a-form possesses a longer C-terminal region than the b-form, which lacks the MAP

Kinase dysfunction and kinase inhibitors

Veterinary Dermatology, 2013
With recent advances in molecular biology, abnormalities in cancer cells that contribute to dysregulation of cell survival and proliferation are being characterized with greater precision. Through this process, key abnormalities in cancer cells involving proteins that regulate signal transduction, migration, mitosis and other critical processes have ...

Plant MAP kinase kinase kinases structure, classification and evolution

Gene, 1999
The increasing number of reports describing plant MAP kinase signalling components reflects the cardinal role that MAP kinase pathways are likely to play during plant growth and development. Relationship and structural analyses of plant MAP kinase kinase kinase related cDNAs and genes established, on one hand, the PMEKKs, which may be distinguished ...
