EPIGENETIC SILENCING OF TUMOR SUPPRESSOR GENES

摘要

Provided are methods of identifying a compound that binds to or modulates an activity of a CTCF polypeptide or CTCF polypeptide complex. Also provided are methods of monitoring a cancer state of a cell by detecting a chromatin boundary proximal to a tumor suppressor gene of the cell and by monitoring the formation of a gene-specific CTCF polypeptide complex in the cell. In addition, methods of selecting a treatment or determining a prognosis for a cancer related disease are provided. Provided are recombinant cells comprising recombinant CTCF genes, recombinant cells comprising CTCF knock downs or knock outs, and recombinant laboratory animals comprising CTCF knock downs or knock outs.
