Methylation and Expression of Retinoblastoma and Transforming Growth Factor-1 Genes in Epstein-Barr Virus-Associated and -Negative Gastric Carcinomas
Figure 2
The protein expression of RB and TGF-β1 by immunohistochemistry (magnification ×100). (a) Positive immunohistochemistry result of RB in paraffin section. Expression of RB was found in nuclei of gastric carcinoma cells. (b) Positive immunohistochemistry result of TGF-β1 in paraffin section. Expression of TGF-β1 was found in cytoplasm of gastric carcinoma cells. (c) Negative immunohistochemistry result of RB in paraffin section. (d) Negative immunohistochemistry result of TGF-β1 in paraffin section.
