QRT-PCR analysis of selected common cancer genes in initial screens

*Fold change: negative and positive values indicate an increase and decrease in expression level of tumor tissues compared with normal tissues for each gene, respectively.**P-value: one tailed Z-test comparing expression difference between normal and tumor groups.***Consistency: the percentage of paired samples used for QRT-PCR having the same regulation tendency in microarray data.****Genes marked bold are top ten scoring genes chosen for QRT-PCR analysis in expanded samples.
