NRP1 and carcinoma of esophagus: Figure 1c shows the upregulation of the NRP1 transcript levels in CHOL (cholangio carcinoma), ESCA (esophageal carcinoma), HNSC (head and neck squamous cell carcinoma), KIRC, and LIHC (liver hepatocellular carcinoma), including STAD. However, downregulation of NRP1 transcription level was confirmed in BRCA (breast invasive carcinoma), COAD (colon adenocarcinoma), KICH, LUSC, READ (rectum adenocarcinoma), and UCEC. Collectively, data from all three databases shows that NRP1 mRNA expression in STAD was significantly higher compared to in normal tissues.
