Figure 1

Clustering analysis of the expression ratio of the sense and antisense pair of transcripts showing altered expression balances. Only the clustering result obtained by the random priming approach is shown. The green color indicates higher expression (threefold or more) of the sense transcript compared with its antisense counterpart. The red color indicates lower expression of the sense transcript (1/3-fold or less) compared with its antisense counterpart. (a) Clustering result for sense-antisense pairs where the sense gene is up-regulated and the corresponding antisense gene is down-regulated in cancer tissues. (b) Clustering result for sense-antisense pairs where the sense gene is down-regulated and the corresponding antisense gene is up-regulated in cancer tissues.
