Berlin, Germany, and Seattle, WA, U.S.A., January 5, 2012 (euro adhoc) -
Epigenomics AG (Frankfurt Prime Standard: ECX), the German-American cancer
molecular diagnostics company, is pleased to announce the publication of a study
authored by Professor Matthias Ebert at University of Heidelberg entitled
"TFAP2E-DKK4 and Chemoresistance in Colorectal Cancer" in the January edition of
The New England Journal of Medicine.

In this study involving more than 200 patients in four independent cohorts,
Professor Ebert and his team demonstrated that hypermethylation of the TFAP2E
gene was correlated with non-responsiveness to the commonly used
chemotherapeutic agent 5-fluorouracil (5-FU). 

Furthermore, using a combination of data from cancer cell lines and patient
samples, the authors demonstrated that this effect was potentially mediated
through up-regulation of the DKK4 gene, previously implicated in 5-FU
resistance.Resistance to treatment was observed with 5-FU based chemotherapy or
5-FU chemotherapy combined with radiation, indicating that TFAP2E methylation
may be a valuable biomarker for response prediction in either setting. 

Epigenomics co-author, Dr. Cathy Lofton-Day commented that "This is one of the
first studies to identify a methylation based biomarker for resistance to
chemotherapy, and may provide caregivers with information to allow a more
informed choice of 5-FU based chemotherapy treatment selection for patients with
colorectal cancer". 

The study represents an important step forward in the growing role that
biomarkers can play in the management of cancer and other diseases. Professor
Ebert commented: "In practical terms, we believe this study demonstrates the
potential that novel DNA methylation biomarkers may have in improving the
selection of therapies for this deadly disease. A prospective validation of the
marker is, however, still required". 

Epigenomics believes that this study demonstrates the potential of TFAP2E and
other biomarkers identified in Epigenomics' DNA methylation discovery pipeline
in supporting clinical decision making.
