FAM155B expression showed significant positive correlations with tumor stage in several cancers, including esophageal carcinoma (ESCA), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), pancreatic adenocarcinoma (PAAD), stomach adenocarcinoma (STAD), and thyroid carcinoma (THCA) (Figure 3). This evidence concerns the gene NALF2 and pancreatic adenocarcinoma.
