55,56) Based on a modified clustered regularly interspaced short palindromic repeats/CRISPR associated proteins (CRISPR/Cas) system, in which dCas9, a nuclease-deficient form of Cas9 (DNA-binding molecule), is fused with TET1 or DNMT3A and expressed together with guide RNAs, dCas9-TET1 or -DNMT3A achieves demethylation or methylation of targeted promoter regions, respectively.
Trovagene will use its PCM technology to profile other dominant AML markers, such as FLT3, DNMT3A, NRAS, and KIT, to identify and measure patient therapy response.

FLT3 (fms-like tyrosine kinase 3) and DNMT3A (DNA methyltransferase) mutations were assessed using PCR-based methods in all AML patients, as previously described [22, 23].
Bioactive nutrients including curcumin offer great potential in altering DNA methylation status which is catalyzed via DNMT1, DNMT3A and 3B.
Although these enzymes place in the same category of enzymes and have second catalytic characteristics but may have different role in tumor development: DNMT3A deletion can stimulate and grow the tumor (Gao, 2011) in the other hand, DNMT3B deletion can stop tumor creation through the deployment and activation of tumor suppressor genes have got silent earlier (Nosho, 2009; Linhart, 2007).
La mayor parte de ellas se encontraron en tres genes: DNMT3A, TET2 y ASXL1.
The majority of mutations occurred in just three genes; DNMT3A, TET2, and ASXL1.
