TRPA1 and cholangiocarcinoma: From these data, we deduced that TRPA1 mRNA expression was significantly upregulated (Wilcoxon test, p < 0.05) in tumours from invasive breast carcinoma (BRCA), cholangiocarcinoma (CHOL), head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC), prostate adenocarcinoma and (PRAD) and thyroid carcinoma (TCHA).
