These factors could include cytoskeletal rearrangements and expression, calcium fluxes, cell interactions with stroma, matrix, or other cells, shape changes, altered expression of import proteins, or a specific phosphorylation signal on ERK [42].
Bacterial zinc homeostasis is accomplished by a coordinated control of uptake, storage and export, which is mainly a result of controlled expression of import and export systems, each one governed by its own regulatory system [ 3].
The expression of imported foreign DNA from within the mitochondrion in a higher eukaryote cell has yet to be demonstrated.
Depending upon the metabolic state of the cell, the expression of human import motor components is highly regulated, thus controlling the import process.
Among these strains dynamically regulating nitrogen, SK1 dramatically upregulated expression of allantoin import and degradation genes, particularly early in the pathway, whereas L-1528 showed abundant expression of urea amidolyase Dur1,2 (supplementary fig. S8 a, Supplementary Material online).
We therefore investigated contraction-evoked changes in the expression of mitochondrial protein import machinery, including mtHSP70, Tim17, and Tim23 in SS and IMF mitochondrial subfractions isolated from the control and chronically stimulated muscles of young and old animals.
Our study and those described above suggest that expression and import of nuclear synthetases might provide a novel therapy for mitochondrial tRNA diseases.
Cytoplasmic expression and import of bI4 maturase by Δ ccm1 segregants were performed as previously described [ 7], but it failed to remove the bI4 intron.
In contrast, the expression of the AI-2 import regulator genes lsrR and lsrK was decreased.
Instead, cell-to-cell variability in lipid droplet formation is dependent on the cascade responses of an insulin signaling pathway which includes insulin sensitivity, kinase activity, glucose import, expression of an insulin degradation enzyme, and insulin degradation rate.
DOI: http://dx.doi.org/10.7554/eLife.07735.007 To modulate the concentration of actin in the nucleus, we knocked down expression of either the nuclear import factor, IPO9, or the nuclear export factor, XPO6.
