Genetic signature of vulnerability to inhibitors of base excision repair (BER) in cancer

摘要

The invention relates to the identification of genetic signatures and expression profiles that are a part of the Base Excision Repair (BER) pathway, a major DNA repair pathway that modifies base lesions. In one embodiment, the present invention provides a method of determining responsiveness of treatment by BER inhibitors for malignant glioma by determining the presence of a low level of expression of Apex 1, a low level of expression of Apex 2, and a high level of expression of MPG.
