Prostate cancer associated modules identified by RegMOD. The square nodes refer to known prostate caner related genes. (A), (B) and (C) are three down-regulated modules PCDM1, PCDM2 and PCDM3 which are related to cell adhesion, receptor binding and cell growth respectively. (D) and (E) chart box-plot of the similarity among genes and the SNR of genes involved in active modules found by different methods. (F) chats the distribution of prostate cancer genes on different gene ranking lists. (G) charts comparison of modules' coverage of known prostate cancer related genes using different methods.
