AGS3 and Gα_i3 Are Concomitantly Upregulated as Part of the Spindle Orientation Complex during Differentiation of Human Neural Progenitor Cells

Molecules, 2020
Adult neurogenesis is modulated by many Gi-coupled receptors but the precise mechanism remains elusive. A key step for maintaining the population of neural stem cells in the adult is asymmetric cell division (ACD), a process which entails the formation ...

Amyloid‐Mediated Remineralization for the Prevention of White Spot Lesions in Orthodontic Treatments

Advanced Materials Interfaces, EarlyView.
This study introduces phase‐transitioned lysozyme (PTL) coatings that trigger layer‐by‐layer hydroxyapatite growth on enamel. The PTL‐induced mineral shield mimics natural enamel structure, providing robust acid resistance and mechanical protection. Acting as a sacrificial barrier, it prevents biofilm‐induced demineralization and enables self‐repair ...

A nuclear-derived proteinaceous matrix embeds the microtubule spindle apparatus during mitosis

Molecular Biology of the Cell, 2012
The concept of a spindle matrix has long been proposed. Whether such a structure exists, however, and what its molecular and structural composition are have remained controversial. In this study, using a live-imaging approach in Drosophila syncytial embryos, we demonstrate that nuclear proteins reorganize during mitosis to form a highly dynamic ...

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

Advanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

Mechanism of how augmin directly targets the γ-tubulin ring complex to microtubules [PDF]

, 2018
Microtubules (MTs) must be generated from precise locations to form the structural frameworks required for cell shape and function. MTs are nucleated by the γ-tubulin ring complex (γ-TuRC), but it remains unclear how γ-TuRC gets to the right location ...

Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

Advanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.

Calcitonin Gene‐Related Peptide (CGRP)‐Expressing Neurons in the External Lateral Parabrachial Area Regulate Pain‐Induced Sleep Disturbances

Advanced Science, EarlyView.
Lynch et al., identified novel targets on the wake‐promoting pathways that can effectively treat pain‐induced sleep disturbances. The authors demonstrated that Calcitonin gene‐related peptide‐expressing neurons (CGRP) in the external lateral parabrachial nucleus (PBelCGRP) serve as the primary relay node for pain stimuli that cause sleep disruption ...

Role of the Putative Zinc Finger Domain of Saccharomyces cerevisiae DNA Polymerase epsilon in DNA Replication and the S/M Checkpoint Pathway [PDF]

, 1998
It has been proposed that C-terminal motifs of the catalytic subunit of budding yeast polymerase (pol) epsilon (POL2) couple DNA replication to the S/M checkpoint (Navas, T. A., Zheng, Z., and Elledge, S. J. (1995) Cell 80, 29-39).
