The comparison of WISP1 mRNA levels among diverse cancer types and adjacent normal tissues in TIMER revealed significantly higher WISP1 expression in breast invasive carcinoma (BRCA), colon adenocarcinoma (COAD), esophageal carcinoma (ESCA), head and neck cancer (HNSC), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC), rectum adenocarcinoma (READ), and stomach adenocarcinoma (STAD). This evidence concerns the gene CCN4 and squamous cell lung carcinoma.
