Besides, TRPC1 mRNA expression was higher in carcinoma tissue compared with para‐carcinoma tissue (Z = −8.438, p < 0.001, Figure 1D) as well; meanwhile, TRPC1 mRNA expression exhibited a good capability in distinguishing carcinoma tissue from para‐carcinoma tissue (AUC: 0.839; 95% CI: 0.789–0.889; Figure 1E). This evidence concerns the gene TRPC1 and carcinoma.
