Yehuda and coworkers (2009) examined the expression of all genes active in whole-blood samples as well as cortisol levels in people with and without PSTD.
Similarly, shading treatment induced genes associated with glycolysis, but also led to changes in the expression of genes for carbohydrate active enzymes, i.e., induction of beta-glycosidases and glycosyltransferase and repression of alpha-glycosidases.
A higher cytokinin status in the roots activated the expression of numerous genes normally expressed predominantly in the shoot, while a lower cytokinin status in the shoot reduced the expression of genes normally more active in the shoot to a more root-like level.
The active expression of genes related to these GO terms was also revealed with other analyses.
Similarly as before for enhancers linked to genes, we find a correlation of the relative expression change of genes hosting active or silenced enhancers.
The researchers measured expression patterns of four genes active in the enamel knots.
During interphase, the genome is packaged to permit expression of active genes and facilitate the silencing of inactive genes, all while maintaining plasticity to allow for variation in gene expression in response to the environment (reviewed in Branco and Pombo 2007; Heard and Bickmore 2007).
During cellular differentiation, enhancers that control the expression of genes involved in lineage specification become active.
For instance, RB recruits SUV39H1 to its target promoters to mediate transcriptional repression [ 33] and may therefore limit the expression of genes that are required for the active cell cycle.
Systemin also upregulates the expression of genes involved in the production of biologically active VOCs.
