Methods of detecting breast cancer brain metastasis with genomic and epigenomic biomarkers

摘要

The present invention provides a method of diagnosing a breast cancer central nervous system (CNS) metastasis in a subject, comprising determining the expression level of at least one biomarker in a subject-derived brain or breast tissue comparing the subject-derived expression level with a normal control level obtained from normal brain or breast cells; and correlating an increase or decrease of the subject-derived expression level as compared to the normal control level to a diagnosis of a breast cancer CNS metastasis. The present invention also provides a method for the treatment of a breast cancer CNS metastasis in a subject comprising administering to the subject an inhibitor of an overexpressed gene associated with CNS metastasis.
