The expression of CNN1 in bladder carcinoma (BLCA), BRCA, cervical squamous cell carcinoma (CESC), COAD, esophageal adenocarcinoma (ESCA), KICH, kidney renal papillary cell carcinoma (KIRP), LUAD, lung squamous cell carcinoma (LUSC), rectum adenocarcinoma (READ), PRAD, STAD, thyroid carcinoma (THCA), and UCEC tumor tissues was significantly lower than that in para-carcinoma tissues, while the protein expression level of CNN1 in CHOL and LIHC tumor tissues was higher than that in para-carcinoma tissues (Figure 1A). Here, CNN1 is linked to urinary bladder carcinoma.
