Persistence of gene expression changes in noninflamed and inflamed colonic mucosa in ulcerative colitis and their presence in colonic carcinoma

Figure 2 RT-PCR analysis of HOXa4 gene expression in normal colonic mucosa and UC mucosa (inflamed, non-inflamed). A: Showed RT-PCR was performed on four paired inflamed mucosa (I) and non-inflamed mucosa (NI) samples in UC as well as six normal control mucosa (N1-N6) G3PDH was used as a control for cDNA synthesis; B: Semiquantification of HOXa4 gene expression (HOXa4/G3PDH) was performed in six paired UC mucosa and six normal control mucosa using NIH image software.
