Enhanced reaction kinetics in biological cells

, 2008
The cell cytoskeleton is a striking example of "active" medium driven out-of-equilibrium by ATP hydrolysis. Such activity has been shown recently to have a spectacular impact on the mechanical and rheological properties of the cellular medium, as well as

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management

Advanced Science, EarlyView.
Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

Dipyridamole Acts as Clinical Ferroptosis Inhibitor to Prevent from Tissue Injury

Advanced Science, EarlyView.
Dipyridamole acts as a clinically used compound to suppress ferroptosis. Dipyridamole down‐regulates the expression of RNF126, which is an E3 ligase to ubiquitinate SLC7A11 for proteasome degradation. The deficiency of SLC7A11 largely abolishes the protective role of dipyridamole both in vitro and in vivo.

Motor-free actin bundle contractility driven by molecular crowding

, 2015
Modeling approaches of suspended, rod-like particles and recent experimental data have shown that depletion forces display different signatures depending on the orientation of these particles.

Respiration Drives Dynamic Metal–Organic Framework for Smart Photoresponse to Volatile Toxic Vapors and Their Photodynamic Sterilization

Advanced Science, EarlyView.
The flexible AIEgen (H4TPPE) with obvious molecular rotor structure is used as a linker to connect with the octahedral Zr6O4(OH)8(H2O)4 cluster‐based SBU to obtain the first smart luminescent MOF (Zr‐TPE‐MOF) with dynamic respiration driven by toxic vapors.

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

Advanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Evolution: functional evolution of nuclear structure. [PDF]

, 2011
The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that ...

Observation of Flux Reversal in a Symmetric Optical Thermal Ratchet

, 2004
We demonstrate that a cycle of three holographic optical trapping patterns can implement a thermal ratchet for diffusing colloidal spheres, and that the ratchet-driven transport displays flux reversal as a function of the cycle frequency and the inter ...

UTX Responds to Nanotopography to Suppress Macrophage Inflammatory Response by Remodeling H3K27me3 Modification

Advanced Science, EarlyView.
Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...
