Differential expression between tumor tissues vs. non-tumor tissues (chromosome 19). a) An example of transition from a brain low TDF region on chromosome 19 (53 Mbp–58 Mbp) in normal tissue libraries to high TDF region in brain tumor libraries; b) Corresponding non-tumor breast tissue vs. tumor breast tissue transcriptome map on the same chromosome. The brain low TDF region observed that changed to high TDF region in a) was not observed in b).
