Oncogenes activated by hypomethylation have been understudied relative to the converse process of gene repression by hypermethylation and represent putative targets for therapeutic inhibition.
One possible explanation for this phenomenon is that glucose represses the expression of genes necessary to the catabolism of xylose through Mig1 an important and essential transcription factor for the process of catabolic repression.
An miRNA:mRNA duplex with a flexible loop would have the ability to form different conformations to meet all of the needs in the complex process of translational repression.
Demethylation of histones H3K4 at gene promoters is an active process of transcriptional repression and may represent a mechanism by which Egr2 regulates the miR-17-92 miR-17-92 miR-17-92
For example, the incorporation of a molecule capable of competing with ribosomes would allow us to model the process of translation repression by small regulatory RNAs, which inhibit translation initiation by competing with ribosomes [ 55].
We have also shown that progestin treatment promotes a decrease in H3K9ac and H4ac, which suggests the involvement of additional mechanisms in the process of GATA3 repression, such as recruitment of histone deacetylases.
Once cell polarity is established in epithelial tissues, it is maintained through a highly conserved, self-sustaining process of mutual repression between the apical and lateral protein complexes (Betschinger et al., 2003; Bilder et al., 2003; Tanentzapf and Tepass, 2003).
Considering that all four reference ICCG genes display cell cycle-associated expression (Additional file 8: Figure S7), it was possible that decreased mRNA amounts in DNMT1-depleted cells reflected a reduced proportion of proliferating cells rather than a process of gene repression.
The case pits an unusually well-connected legal activist against highly placed political figures, and it touches on a variety of human rights issues including police misconduct, arbitrary detention, violations of privacy, land grabbing, neglect of due process and repression of freedom of expression, the report said.
It is well known that AKT plays an important role in the process of EMT via repression of E-cadhrin [ 49].
