In the midgut, 34 out of 43 genes had a significantly modified expression pattern after a blood meal [ 42].
Together, these expression patterns not only help to validate the ChIP-chip data, but they also reinforce a common theme, which is that Ubx is modifying expression patterns, not simply turning genes on or off throughout the entire haltere.
It remains unclear how epigenetic modifications fix the effects of early environmental events, in a sex-specific manner, ensuring sustained responses to transient stimuli and resulting in modified gene expression patterns and phenotypes later in life [68].
Even as engineering challenges have been overcome, investigations have shown that plants in various growth systems do respond to spaceflight with modified gene expression patterns.
In addition to the absence of the modified gene expression patterns seen in clusters 4 and 12, there is another pair of clusters that represent the opposite tendency.
Respective studies in solid tumours are summarised in table 1. Regarding urological tumours, modified FABP expression patterns were described for prostate [ 2] and urinary bladder cancer [ 3] as well as for renal cell carcinoma [ 4].
Overall, these experiments and results have confirmed previously reported responses to abiotic stresses while addressing previously unknown details and fundamentally advancing our understanding of how modified gene expression patterns facilitate acclimation to abiotic stresses.
The use of antisense oligonucleotides (ON) to modify aberrant expression patterns of alternatively spliced mRNAs is a novel means of potentially controlling such diseases.
