Fig. 4From: Phosphodiesterases in non-neoplastic appearing colonic mucosa from patients with colorectal neoplasiaExpression levels for PDEs. Expression of subtypes PDE4B and PDE5A was significantly higher in the CRN patient group. For controls in PDE5A (N = 4, n = 4), PDE4B (N = 5, n = 5), PDE4D (N = 5, n = 5). For neoplasia in PDE5A (N = 5, n = 5), PDE4B (N = 8, n = 8), PDE4D (N = 8, n = 8). Expression levels are relative to ß-actin. Data presented as means ± SEM. *p < 0.05 and **p < 0.01Back to article page
