Results of the immunofluorescence assay of the transverse gastric sections and the myenteric plexus showed that the glial cells (GFAP/S100B, P < 0.01, Fig. 5G, I) and neuronal cells (HuC/D/β-Tubulin, P < 0.01, Fig. 5H, J) were significantly decreased in the BAC group compared with the control. This evidence concerns the gene S100B and minimally invasive lung adenocarcinoma.
