Inverse correlation between the expression of GPR55 and miR-675-5p in clinical specimens of NSCLC. (A, B, C) The expression of GPR55 was assessed in normal and NSCLC tissues using immunohistochemistry. The images were representative IHC of GPR55 in normal, squamous carcinoma, and adenocarcinoma, respectively. (D) A scatter diagram showed an inverse correlation between the expression of miR-675-5p and GPR55 in the same set of NSCLC tissue specimens. (original magnification ×400).
