Moreover, chronic migraine and chronic tension type headache showed a relationship between short sleep duration and increased expression of central sensitization symptoms as pericranial tenderness, suggesting a reverberating mechanism where headache frequency, low pain threshold, reduced sleeps time and psychopathological factors interfere in a complex way in generating chronic syndromes [14].
Therefore, we assessed whether a correlation between disease duration and kif21b expression existed.
Kaplan Meier plots and the log-rank test were used to evaluate the association between survival duration and the expression of the three genes.
Detection success largely depends on two parameters: signal strength (the fraction of GFP-positive cells in the animal and how brightly each cell fluoresces) and expression duration (a transiently expressed gene is less likely to be detected).
The plasmid loading regulated the quantity and duration of transgene expression, with expression for 105 days achieved at the highest dosage.
In order to better understand the relationship between disease duration and changes in expression of investigated molecules, patients were divided into those with short- and long-term disease.
Such feed-forward loops allow the cell to modulate the timing, duration and location of expression of subsets of genes within a regulon.
Our recent contributions within this topic, that illustrate the constructive role of stochasticity, include the noise-induced coherence resonance phenomenon in multicellular circadian clocks [ 24] and the interplay between the stochasticity of the cell cycle duration and the protein expression noise in bacterial colonies [ 25].
The corrected gene would be under the control of its cognate control sequences, ensuring cell-specific and appropriate level and duration of expression [ 3].
The different technologies are functionally graded with respect to safety, expression magnitude and expression duration.
Taken together, our results indicate that the distinct mRNA expression patterns in cells treated in transient and sustained modes are, at least in part, linked to the duration of ERK1/2 activation and expression of the AP-1 components like JUNB as well as the ATF subfamily proteins ATF4 and ATF3 for which the mRNA expression levels are prolonged only in the sustained mode.
