E74 encodes two transcription factor isoforms, E74A and E74B, which act to induce and repress, respectively, transcription of downstream genes, thus achieving a precise regulation of the timing of downstream responsive genes during ecdysis [58].
In this report we show that CTCF expression in the prothoracic gland is required for full transcriptional activation of the Halloween genes spookier, shadow and noppera-bo, which encode ecdysone biosynthetic enzymes, and for proper timing of ecdysone-responsive gene expression.
light on whether the timing of death is responsive to its tax consequences.
This suggests that the Pi stress-responsive expression is also regulated by alternative splicing mechanisms with respect to the timing of the response or tissue specificity.
Overall, the timing of the expression of hormone-responsive genes fits well with the accumulation of these hormones in wheat grain [ 60, 61].
"The orchestra is responsive to the timing of the dancers — it's like custom-made," said Joan Hope MacNaughton, the company's founder and artistic director.
Fig. 5 Validation of responsive unannotated transcripts.
(D4 ) Comparison of responsive and non-responsive GoCs firing rates.
Changes in the timing of seasonal activities of organisms over time may be the most responsive and easily observable indicator of environmental changes associated with global climate change.
Additional studies are needed to better define the optimal timing of PET during neoadjuvant therapy to detect poorly responsive tumors and allow early intervention.
