Distribution of IL-8-tumor related genes in all tumor cDNA libraries. The percentage ratio of IL-8-tumor clones/tumor clones (Ril8tumor) was calculated for IL-8-tumor related genes. The result is plotted here with gene id on the x-axis and Ril8tumor on the y-axis, and is ordered by decreasing Ril8tumor. Only the top half genes (21) with relatively high Ril8tumor are displayed. The 3 most specific genes are GW112 protein (86.2%), PS1 (81.1%), and KLF2 (76.4%).
