Logarithmic expression profile value of twenty-one genes determined by quantitative reverse transcription-PCR by using the Comparative CT method. Three housekeeping genes were used to normalize input cDNA for each sample with colorectal cancer, with cDNA of normal tissue used as calibrator. Crosses represents mean of triplicate determinations. *P < 0.05; ° P < 0.01; ^ P < 0.001.
