In these samples, obestatin (Figure 5A1 and 5B1) was negative in all of the gastric adenocarcinomas studied (Figure 5A3 and 5B3), whereas intense staining was found in the neuroendocrine cells of the healthy gastric mucosa (Figure 5A2 and 5B2), although it was negative in the rest of the oxyntic mucosa. The gene discussed is GHRL; the disease is gastric adenocarcinoma.
