Once the model was validated, a study was performed to determine the modifications that should be made in the reactor to optimize the irradiation facility without perturbing the normal operation of the reactor.
Further MSC preparations isolated under different culture conditions and other cell types need to be considered to determine epigenetic modifications that are characteristic for adult stem cells [32].
The algorithm used to determine interaction modifications that stabilize a network attractor in response to node damage is presented in a concise pseudo-code format.
Lander and Bernstein similarly determined specific histone modifications that distinguish actively expressed genes, genes poised for expression, and repressed genes in different kinds of cells.
In some cases, such as at H3K27 and H3K9, acetylation or methylation can occur at the same histone residue and it is the balance between these opposing modifications that determines the transcriptional status of that region (Rice and Allis, 2001; Tie et al, 2009; Jung et al, 2010; Pasini et al, 2010b).
To this purpose, proteomics studies are a powerful tool to better understand where to set the boundary line of healthy aging and age-related disease by analyzing the variation of protein expression levels and the major post translational modifications that determine "protein" physio/pathological fate.
On the other hand, measuring expression of the inflammatory mediator genes may not reflect the functional activity of the end-protein, because this also depends on translation and various posttranslational modifications that determine whether the protein becomes active.
They also demonstrate how opposing hormonal and intracellular signals can be integrated via histone modifications that determine chromatin structure and transcriptional activity of the promoter.
Alternatively, establishment of good biomarkers for detection of weak checkpoint signaling, such as antibodies to post-translational modifications that determine strong vs weak signaling, may facilitate this.
Surface and cytoplasmic nucleolin are differentiated from nuclear nucleolin by a slight shift in their isoelectric point, probably as a consequence of specific co- and/or post-translational modifications that determine routing of the newly synthesized nucleolin to the nucleus or the plasma membrane [6].
When HMGB1 emerges from the cell during apoptosis, necrosis, or pyroptosis, it can have redox and other post-translational modifications that determine its activity.
