Clustering analysis based on gene function showed down-regulation of some genes for cell proliferation and cell cycle progression (cyclin A, cyclin F, CDC2, CDK2, etc), transcription factors (transcription factor A, ATF5, TAF1131L, FOXM1, etc), and oncogenesis (GRO oncogene, BRCA1 associated RING domain, tumor-associated nuclear protein p120, etc) in Taxotere and/or Furtulon treated prostate cancer cells (Table 2 and 3). Here, CCNF is linked to Familial prostate cancer.
