Analysis of genes affected by cancer and diet. Left, changes in the expression of sorted genes between flax-normal vs. control-cancer (FN-CC) was visualized by heat map. Right, Venn diagram of overlapping genes among the different data sets viz. control-cancer vs. control-normal (CC-CN), flax-cancer vs. flax-normal (FC-FN) and flax-normal vs. control-normal (FN-CN) dataset. Genes are listed in additional file 2.
