The expression of PDGF-BB predicts curative effect in locally advanced esophageal squamous cell carcinoma treated by radiotherapy

Figure 2. PDGF-BB expression in esophageal squamous cell carcinoma tissues and cell-lines was studied in a total of 41 cancer tissues (62.1%) of all 66 cases, and these cases had high expression (score: < 2) in PDGF-BB (A) while the expression was low in all 4 normal adjacent operative tissues (B) by immunohistochemistry. In addition, Western blotting showed that the levels of PDGFB were positively expressed in the 4 esophageal squamous cell carcinoma cell-lines (C).
