Classification of targets and links contained in two adjacent GRNs

Comparison	Groups	No. of targets (%)	No. of links (%)
Normal vs. Adenoma	Common	132 (15.2%)	285 (18.1%)
	Differential (varied and stage-specific)	770 (84.8%)	1228 (81.9%)
Adenoma vs. Carcinoma	Common	145 (15.7%)	241 (15.4%)
	Differential (varied and stage-specific)	781 (84.3%)	1323 (84.5%)

“Differential” means targets or links with substantial changes between two stage-specific GRNs; “common” means targets or links with only slight or no changes between two stage-specific GRNs.
