摘要: This chapter discusses a genomic approach to the treatment of breast cancer. Using DNA microarray or proteomic analysis, it should be possible gain an understanding unique susceptibilities individual's cancers. Already, feasibility this analyzing human cancer has been reported, and new concept suggested for origins classification In cancers fell into at least three groups: those luminal cell origin (ER-positive), basal epithelial (ER-negative), HER2/ neu (Erb-2)-positive cells. Each one these was characterized by high expression specific subset genes. Furthermore, recently shown that mutations in BRCA1 BRCA2 can independently influence transcription profile Therefore, sort data viewing all pathways involved ultimate outcome drug-target interaction. way, may select drug is likely effective over not. The work with MCF-7 line which microarrays were done before after doxorubicin, most drugs
