A significant decrease in vinculin expression was observed in tumor tissue compared with healthy mucosa (mean ± SD: 0.75 ± 0.51 vs. 1.46 ± 0.89, p < 0.001; Table 3 and Figure 4), as well as in vimentin (0.78 ± 0.80 vs. 4.08 ± 4.88, p < 0.001; Table 3 and Figure 4). This evidence concerns the gene VIM and neoplasm.
