Biochemical reconstitution of branching microtubule nucleation
eLife, 2020 Microtubules are nucleated from specific locations at precise times in the cell cycle. However, the factors that constitute these microtubule nucleation pathways and their mode of action still need to be identified. Using purified Xenopus laevis proteins

On the Nature and Shape of Tubulin Trails: Implications on Microtubule Self-Organization [PDF]
Acta Biotheoretica 60, 1 (2012) 55, 2012 Microtubules, major elements of the cell skeleton are, most of the time, well organized in vivo, but they can also show self-organizing behaviors in time and/or space in purified solutions in vitro. Theoretical studies and models based on the concepts of collective dynamics in complex systems, reaction-diffusion processes and emergent phenomena were ...

Synthetic Active Liquid Crystals Powered by Acoustic Waves
Advanced Materials, EarlyView.A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

Advances in the pathogenesis of Rett syndrome using cell models
Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 532-541, December 2022., 2022 Most Rett syndrome (RTT) patients are affected by the MECP2 gene mutations. And the mutations of MECP2 have wide effects on different cell types of nervous system, including neurons, astrocytes, oligodendrocytes and microglia, which always combined together to lead to abnormalities in the whole neural network.

Advanced Synthesis &Catalysis, EarlyView.Abstract Allenes tethered to pyrroles undergo Au(I)‐catalyzed hydroarylation leading to tetrahydrodiazepines or tetrahydrodiazonines. The regioselectivity of the reaction is governed by both the substitution pattern of the allene and the nature of the Au(I) ligand. Hence, alkyl‐gem‐disubstituted allenes preferentially lead to tetrahydrodiazepines via 7‐

Stabilization of microtubules due to microtubule-associated proteins: A simple model [PDF]
arXiv, 2003 A theoretical model of stabilization of a microtubule assembly due to microtubule-associated-proteins(MAP) is presented. MAPs are assumed to bind to the microtubule filaments, thus preventing their disintegration following hydrolysis and enhancing further polymerization.

Advanced Sensor Research, EarlyView.Elevated levels of Tau in cerebrospinal fluids or other body fluids are associated with the progression of Alzheimer's disease. An optical technique, based on a dual label‐free and fluorescence operation mode, is developed to detect Tau protein in both standard running buffer and cerebrospinal fluid.

Non-centrosomal MTs play a crucial role in organization of MT array in interphase fibroblasts
AIMS Genetics, 2018 Microtubules in interphase fibroblast-like cells are thought to be organized in a radial array growing from a centrosome-based microtubule-organizing center (MTOC) to the cell edges.
