Histone-modifier gene expression profiles are associated with pathological and clinical outcomes in human breast cancer.

Abstract

Expression levels of histone-modifier genes in breast cancer differ significantly from normal tissue. Differences in expression profiles exist between breast tumors and are significantly associated with conventional pathological parameters and clinical outcomes. Further study is warranted to determine the consequences of altered expression for each specific histone-modifier gene and the biological and clinical implications of combinatorial variations in expression profiles. Histone-modifier enzymes offer utility as biomarkers and potential for targeted therapeutic strategies.
