Increased expression of GAPDH mRNA in colorectal adenoma. a The relative GAPDH expression were calculated using the average of GAPDH expression values from the gene expression profiles in the NCBI GEO database generated from the Affymetrix Human Genome U133 Plus 2.0 Array (Sabates-Bellver J. et al. 2007, accession GDS2947) of the paired colorectal adenoma and normal mucosa sample from each patient (n = 32), each normalized by its β-actin (ACTB) expression. b Comparison of relative GAPDH expression in colorectal adenomas and normal colon mucosa. The relative expression values were calculated using the averages of GAPDH expression values normalized by ACTB expression values of 32 pairs of colorectal adenomas and normal mucosas. The statistical significance was calculated by two-tailed t test (p<0.0001)
