Figure 1From: Oncogenic role of the chromobox protein CBX7 in gastric cancerThe expression of CBX7 in gastric cancer cell lines and gastric tumors. A) The expression of CBX7 and p16 proteins in an immortalized human normal gastric epithelial cell line GES-1 and various gastric cancer cell lines as detected by Western blot analysis. β-actin was used as a loading control. B) Examples of nuclear staining of CBX7 in normal gastric tissues and gastric cancer tissues by IHC detection: negative CBX7 expression in normal gastric tissue (upper left); negative CBX7 expression (upper right), slight positive CBX7 expression (lower left), and strong CBX7 expression (lower right) in gastric cancer tissues. Tissue sections were stained with CBX7-specific antibody and counterstained with hematoxylin as described in experimental procedures (magnification: ×400).Back to article page
