Gene deletion of EED, another component of PRC2 complex required for EZH2-mediated H3K27me3, has been reported to induce pancytopenia and increased apoptosis via derepression of p16 and p19 tumor suppressors as well as several EZH2 target genes HoxC4, Id2, Sox7 and Noxa.
Microbial adaptation depends on many factors, such as the induction or derepression of specific enzymes for degradation pathways or an adaptation of existing catabolic enzymes to the degradation of novel compounds.

Moreover, the strategy of silencing EMT inducers, such as Snail, with shRNAs has been shown to exert a double effect: it inhibits the epithelial-mesenchymal change and promotes the inverse mesenchymal-epithelial change via E-cadherin derepression (127).
