Cytochrome P450 levels are altered in patients with esophageal squamous-cell carcinoma

Figure 4 CYP3A5, CYP2E1, CYP3A4, and CYP2C protein levels in esophagus of SCC patients and disease-free controls. A: Representative Western blot of CYPs determined in normal tissue of untreated esophageal SCC patients (S) and disease-free controls (C); B: Quantitative analysis of CYP2C, CYP2E1, CYP3A4, and CYP3A5 protein levels in normal esophageal tissue of SCC patients and disease-free controls. Results are normalized to β-actin. Data are means ± SE. ^aP < 0.05 vs disease-free controls.
