These include, amongst others, p53 mutations, EGF receptor gene amplification, changes in the p21 gene, and consistent alterations in loci on chromosome 10 and in the 17p13.3 locus [ 11- 13].
This technique, similar to principal components analysis, represents expression (hybridisation) as points projected in three-dimensional space and demonstrates a consistent alteration in the transcriptome of cells treated with COX-2 inhibitor.
Among our so-identified differentially expressed genes that also overlap with those reported in each of the above studies, only a small portion of genes, say 7 (out of 21), 4 (out of 6), and 5 (out of 23), shows consistent alteration in SKOV-3 versus other cells.
Of the known components in the three major P-TEFb-containing complexes, the 7SK snRNP, the Brd4-bound complex, and the SEC, only LARP7 and HEXIM1, two signature components of the 7SK snRNP, showed consistent alteration in human breast cancer tissues.
There was no consistent alteration in nucleosome occupancy between the wild-type and mutant alleles at a variety of donor and acceptor sites, which would be expected if nucleosome positioning at these sites played a role in mediating the effects of splice site mutations.
As with the clinical populations discussed above, in those populations that likely have a chronic shift in their CAR, any additional or consistent alteration in CAR seems doubtful.
Therefore, no consistent alteration in the expression of Tif2 could be correlated with proviral insertion at Evi32.
There was no consistent alteration in mitochondrial morphology detectable in TMRM-stained cells (Supplementary Material, Fig. S2B).
Alleles containing donor or acceptor splice site mutations showed no consistent alteration in nucleosome positioning or occupancy.
In addition, we report the consistent alteration in networks of TNF-related genes on acquisition of docetaxel resistance in breast and ovarian tumor cells.
