Intracellular mechanochemical waves in an active poroelastic model [PDF]

open access: yes, 2013
Many processes in living cells are controlled by biochemical substances regulating active stresses. The cytoplasm is an active material with both viscoelastic and liquid properties. We incorporate the active stress into a two-phase model of the cytoplasm

Cytosolic and Nuclear Co-localization of Betalain Biosynthetic Enzymes in Tobacco Suggests that Betalains Are Synthesized in the Cytoplasm and/or Nucleus of Betalainic Plant Cells

open access: yesFrontiers in Plant Science, 2017
Betalains replace anthocyanins as color pigments in most families of Caryophyllales. Unlike anthocyanins, betalains are derived from tyrosine via three enzymatic steps: hydroxylation of L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA; step 1), and ...

Spatial control of irreversible protein aggregation [PDF]

open access: yes, 2018
Liquid cellular compartments spatially segregate from the cytoplasm and can regulate aberrant protein aggregation, a process linked to several medical conditions, including Alzheimer's and Parkinson's diseases.

Undervalued ubiquitous proteins

open access: yes4 open, 2019
The role of ubiquitous proteins (UPs) and their corresponding enzymes have been underestimated in carcinogenesis as the focus of much research revolved around measuring mutations and/or other genetic epiphenomena as surrogate markers of cancer and cancer

3D Computational Modeling of Bleb Initiation Dynamics

open access: yesFrontiers in Physics, 2021
Blebbing occurs in cells under high cortical tension when the membrane locally detaches from the actin cortex, resulting in pressure-driven flow of the cytosol and membrane expansion. Some cells use blebs as leading edge protrusions during cell migration,

Magnetic wire as stress controlled micro-rheometer for cytoplasm viscosity measurements [PDF]

open access: yes, 2018
We review here different methods to measure the bulk viscosity of complex fluids using micron-sized magnetic wires. The wires are characterized by length of a few microns and diameter of a few hundreds of nanometers.

A pH-driven transition of the cytoplasm from a fluid- to a solid-like state promotes entry into dormancy

open access: yeseLife, 2016
Cells can enter into a dormant state when faced with unfavorable conditions. However, how cells enter into and recover from this state is still poorly understood. Here, we study dormancy in different eukaryotic organisms and find it to be associated with

Confocal Raman data analysis enables identifying apoptosis of MCF-7 cells caused by anticancer drug paclitaxel [PDF]

open access: yes, 2013
Confocal Raman microscopy is a noninvasive, label-free imaging technique used to study apoptosis of live MCF-7 cells. The images are based on Raman spectra of cells components, and their apoptosis is monitored through diffusion of cytochrome c in ...

Marker-assisted breeding of onion (A. cepa L.) maintainer line resistant to Downy mildew

open access: yesОвощи России, 2021
Relevance. F1 hybrids breeding programs of onion are based on the use of nuclear cytoplasmic male sterility (NCMS). Breeding and seed production based on NCMS suggest a development of a female sterile maternal line, a maintainer line and a paternal ...
