After a transient response to a change in stimulus, the modification or demodification reactions occur, which shift the equilibrium between two states to compensate for the transient response.
TTP has long been known to be phosphorylated, in some cases in response to external stimuli; this modification has been shown in some reports to impair its ability to stimulate mRNA decay [28], [30], [31], [32], [44], [45], [46], [47].
Stimuli responsive modification of the macrocycle can also drive such shuttling processes.
This training task shows high resemblance to the adaptive PASAT concerning stimuli, responses, modification of task difficulty, and evaluation of session performance.
In the up-regulated gene set there was significant GO term enrichment for "proteolysis and peptidolysis," "effectors and modulators, cell communication" (which mainly corresponds to the children terms "signal transduction" and "response to external stimuli"), "protein modification," and "lipid metabolism".
All previous methods involving closed-loop or activity-guided optogenetic stimulation have used a physiological measurement to trigger static optical stimuli without corrective action or modification of stimulus parameters following stimulus onset (Leifer et al., 2011; Stirman et al., 2011; Paz et al., 2012; Krook-Magnuson et al., 2013; O'Connor et al., 2013; Siegle and Wilson, 2014).
Recently, a new concept of personalized treatment based on metabolomics phenotype has been proposed by Nicholson et al. and termed as pharmacometabonomics. Metabonomics, a special case of metabolomics, studies the systematic variation in the metabolic profiles due to external stimuli such as genetic modification, biological stimulus, and xenobiotic intervention.
Cell-cell interactions are relevant in modulating the response to external stimuli, and modifications of membrane and/or matrix components may activate signaling events that change cell fate [34].
In addition to DNase IIβ, the present studies suggest a large number of differentially expressed genes that belong to GO Biological Process categories: DNA repair, establishment and/or maintenance of chromatin architecture, response to DNA damage stimulus and chromatin modification (see Additional file 11).
The experimental approach enabling this is metabonomics and has been defined as "the quantitative measurement of the dynamic multiparametric metabolic response of living systems to pathophysiological stimuli or genetic modification" [21].
