Growth, invasion, metastasis, differentiation, angiogenesis and apoptosis of gastric cancer regulated by expression of PTEN encoding products

Figure 1 PTEN was immunostained in cell nuclear. It was strongly expressed in gastric epithelial cells (+++) (S-P, ×400).

Figure 2 PTEN was strongly expressed in gastric well-differ-entiated adenocarcinoma (+++) (S-P, ×400).

Figure 3 PTEN was negatively expressed in poorly-dif-ferentiated adenocarcinoma cells (-) and tumor infiltrated lymphocytes showed strong expression of PTEN (+++) (S-P, ×400).

Figure 4 CD34 was located in cytoplasm and cellular mem-brane of vascular endothelial cells (S-P, ×400).

Figure 5 Caspase-3 was distributed in cytoplasm. Caspase-3 was strongly expressed in gastric epithelial cells (+++) (S-P,×400).

Figure 6 Caspase-3 was positively expressed in well-differ-entiated adenocarcinoma of stomach (++), and strongly in tu-mor infiltrated lymphocytes (+++) (S-P, ×400).
