TRPV4 and esophageal squamous cell carcinoma: In this study, we probed for the expression of thermo‐TRPVs in one nontumor esophageal squamous cell line and two esophageal squamous cell carcinoma cell lines, and to our knowledge, for the first time, we characterized the gene expression and cellular localization of TRPV1, TRPV2, and TRPV4 in esophageal squamous cells.
