On Dynamically Generating Relevant Elementary Flux Modes in a Metabolic Network using Optimization [PDF]
Elementary flux modes (EFMs) are pathways through a metabolic reaction network that connect external substrates to products. Using EFMs, a metabolic network can be transformed into its macroscopic counterpart, in which the internal metabolites have been eliminated and only external metabolites remain.

Waves in a Stochastic Cell Motility Model [PDF]
In Bhattacharya et al. (Science Advances, 2020), a set of chemical reactions involved in the dynamics of actin waves in cells was studied. Both at the microscopic level, where the individual chemical reactions are directly modelled using Gillespie-type algorithms, and on a macroscopic level where a deterministic reaction-diffusion equation arises as ...

Nucleotide-sugar transporters (NSTs) form a family of structurally related transmembrane proteins that transport nucleotide-sugars from the cytoplasm to the endoplasmic reticulum and Golgi lumen.

A model of replicating coupled oscillators generates naturally occurring cell networks [PDF]
When a founder cell and its progeny divide with incomplete cytokinesis, a network forms in which each intercellular bridge corresponds to a past mitotic event. Networks built in this manner are required for gamete production in many animals, and different species have evolved very different final network topologies.

Cellular redox changes are common in apoptosis, immune function, signaling pathways and cancer. The authors aimed to develop a single-wavelength method using the superior fluorescence sensitivity of a flow cytometer for measuring redox-sensitive green ...

The cDNA encoding human myeloperoxidase carries three ATG codons in frame; 144, 111 and 66 bp upstream from the proprotein DNA sequence. In order to determine the most efficient signal sequence, three cDNA modules starting at each of the ATG were cloned ...

The proteoglycans of animal cells typically contain one or more heparan sulfate or chondroitin sulfate chains. These glycosaminoglycans assemble on a tetrasaccharide primer, -GlcAβ1,3Galβ1,3Galβ1,4Xylβ-O-, attached to specific serine residues in the core

Background: Improvement of mRNA stability and therefore, production of interferon beta (IFNb) in Chinese hamster ovary (CHO) cell, as a recombinant protein expression system, is very important.
