Topological phonon modes in filamentous structures [PDF]

Phys. Rev. E 83, 021913 (2011), 2010
Topological phonon modes are robust vibrations localized at the edges of special structures. Their existence is determined by the bulk properties of the structures and, as such, the topological phonon modes are stable to changes occurring at the edges. The first class of topological phonons was recently found in 2-dimensional structures similar to that

Basolateral Membrane-associated 27-kDa Heat Shock Protein and Microfilament Polymerization [PDF]

Journal of Biological Chemistry, 1997
The in vivo activity of the 27-kDa heat shock protein, a barbed-end microfilament capping protein, may be localized to the plasma membrane. To investigate this putative association, bovine endothelial cells expressing the human wild type or a mutant nonphosphorylatable 27-kDa heat shock protein were subjected to subcellular fractionation and immunoblot

Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

Advanced Science, EarlyView.
Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Intermediate Filament Protein BFSP1 Maintains Oocyte Asymmetric Division by Modulating Spindle Length

Advanced Science, EarlyView.
Different from mitosis, the female meiosis undergoes asymmetric division that produces haploid oocytes and polar body, which is essential for retaining maternal components to support subsequent fertilization and embryo development. However, the underlying mechanisms are still largely unknown.

Distribution of the cell substratum attachment (CSAT) antigen on myogenic and fibroblastic cells in culture. [PDF]

, 1985
Previous studies (Neff et al., 1982, J. Cell. Biol. 95:654-666; Decker et al., 1984. J. Cell. Biol. 99:1388-1404) have described a monoclonal antibody (CSAT Mab) directed against a complex of three integral membrane glycoproteins of 120,000-160,000 mol ...

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 ...

Coordination of microtubule and microfilament dynamics by Drosophila Rho1, Spire, and Cappuccino [PDF]

, 2006
The actin nucleation factors Spire and Cappuccino regulate the onset of ooplasmic streaming in Drosophila1-5. Although this streaming event is microtubule-based, actin assembly is required for its timing.

In silico evidence that protein unfolding is as a precursor of the protein aggregation [PDF]

ChemPhysChem 2020, 21, 377, 2019
We present a computational study on the folding and aggregation of proteins in aqueous environment, as function of its concentration. We show how the increase of the concentration of individual protein species can induce a partial unfolding of the native conformation without the occurrence of aggregates. A further increment of the protein concentration
