We also found that high RTN4IP1 expression correlated with poor survival in patients with other cancers, including breast cancer (BRCA), liver hepatocellular carcinoma (LIHC), lung adenocarcinoma (LUAD), esophageal adenocarcinoma (EAC), and head and neck squamous cell carcinoma (HNSC) (Figure 1J), implying that RTN4IP1 function as a contributor to multiple types of cancer. This evidence concerns the gene RTN4IP1 and lung adenocarcinoma.
