Our work establishes TET1 as a potential oncogene that contributes to aberrant hypomethylation in cancer and suggests that TET1 could serve as a druggable target for therapeutic intervention.<b>Significance:</b> This study addresses a critical gap in knowledge of how and why methylation is prognostic in breast cancer and shows how this information can be used to stratify patients with TNBC for targeted therapy.<i>Cancer Res; 78(15); 4126-37.©2018 AACR</i>.

Our data suggest that the predominantly activated isoform of TET1 in cancer cells does not protect from CGI methylation and likely mediates dynamic site-specific demethylation outside of CGIs.

Mechanistically, TET1 potently inhibited canonical Wnt/β-catenin signaling by demethylating and upregulating two upstream antagonists of this pathway, SFRP2 and DKK1, which was associated with inhibition of EMT and cancer cell metastasis.

Moreover, besides its dioxygenase activity, TET1 could induce epithelial-mesenchymal transition and act as a coactivator to regulate gene transcription, such as developmental regulator in embryonic stem cells (ESCs) and hypoxia-responsive gene in cancer.

Discovery of the enzymatic activity that catalyses oxidation of 5-methylcytosine (5mC) to generate 5-hydroxymethylcytosine (5hmC) mediated by the MLL (KMT2A) fusion partner TET1 has sparked intense research to understand the role this new DNA modification has in cancer.

In conclusion, this work shows that PARP activity is a transcriptional regulator of TET1 gene through the control of epigenetic events and it suggests that deregulation of these mechanisms could account for TET1 repression in cancer.
