Figure 1.

Expression of G-protein-coupled estrogen receptor (GPER) in lung adenocarcinoma and squamous cell carcinoma. The expression of GPER in lung adenocarcinoma is shown in well (A), moderately (B), and poorly (C) differentiated degrees. The expression of GPER in lung squamous cell carcinoma is shown in well (D), moderately (E), and poorly (F) differentiated degrees. Original magnification: 400×. The bar graphs summarize the percentage of lung adenocarcinoma and squamous cell carcinoma that express various amounts of cytoplasmic GPER (G) and nuclear GPER (H) proteins.
