Cytoplasmic chromatin triggers inflammation in senescence and cancer [PDF]
, 2017 Chromatin is traditionally viewed as a nuclear entity that regulates gene expression and silencing. However, we recently discovered the presence of cytoplasmic chromatin fragments that pinch off from intact nuclei of primary cells during senescence, a ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Cytoplasmic Phytochrome Action [PDF]
Plant and Cell Physiology, 2010 Phytochrome photoperception is a common mechanism for the detection of red and far-red light in bacteria, cyanobacteria, fungi and plants. However, the responses following phytochrome activation appear to be quite diverse between species. Lower plants, such as mosses, show phytochrome-mediated directional responses, namely phototropism and ...

Functions of p120ctn in development and disease [PDF]
, 2012 p120 catenin (p120ctn), a component of the cadherin-catenin complex, was the first member to be identified in a most interesting subfamily of the Armadillo family. Several p120ctn isoforms are generated by alternative splicing.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

The electrical resistivity of cytoplasm
Biophysical Journal, 1976 The apparent cytoplasmic resistivity of two different giant cells has been measured using an extension of a previously developed single microelectrode technique. Each cell is penetrated by a metal microelectrode whose complex impedance is measured as a function of frequency between 500 kHz and 5.7 MHz.

Protein Mobility in the Cytoplasm of Escherichia coli [PDF]
, 1999 The rate of protein diffusion in bacterial cytoplasm may constrain a variety of cellular functions and limit the rates of many biochemical reactions in vivo. In this paper, we report noninvasive measurements of the apparent diffusion coefficient of green

Purification tags markedly affect self‐aggregation of CPEB3
FEBS Letters, EarlyView.Although recombinant proteins are used to study protein aggregation in vitro, uncleaved tags can interfere with accurate interpretation. Our findings demonstrate that His₆‐GFP and His₁₂ tags significantly affect liquid droplet and amyloid fibril formation in the intrinsically disordered region (IDR) of mouse cytoplasmic polyadenylation element‐binding ...

On the fractal nature of cytoplasm [PDF]
FEBS Letters, 1994 On the basis of a quantification of the fractal dimension, D, in micrographs of cytoskeleton components or microtrabecular lattice, we propose that the cellular cytoplasm can be described as a percolation cluster, a sort of ‘random fractal’. Our hypothesis deals with: (i) the existence of the percolation threshold — a remarkable property of percolation
