Gene expression analyses.

The 20 most up- or down-regulated genes in the FFPE data set with corresponding RNAlater® values (upper panel), and the 20 most up- or down regulated genes in the RNAlater® dataset with corresponding FFPE values (lower panel), filtered by adjusted p-value≤0.05. Rank indicates the rank of the gene within the list of differentially genes sorted by largest to smallest absolute fold change. 14 genes are shared between the two lists. TU: tumour, NO: normal, FC: fold change, ND: not detected, did not pass the expression filter.
