title: [Epigenetic changes in breast cancer shown by aberrant promoter methylation].
abstract: The aberrant methylation of cytosine residues in the promoter region of growth-regulatory genes is now recognized as an important inactivation mechanism in addition to deletion and mutation in the development and progression of cancer. Principally all pathways regulating proliferation and differentiation, which are perturbed in cancer cells, can be affected. In breast cancer epigenetic inactivation is a frequent and early event displaying great quantitative gene-specific differences during progression. The occurrence of specific aberrant methylation patterns is associated with the histological grade and subtype of mammary carcinoma biopsies.
