GPER1 is expressed in adult GCTs. (A) Immunohistochemistry studies of GPER1 on TMAs of adult GCTs. Shown are tumors with no staining (a) and with moderate staining (b). Tissue sections are counterstained with hematoxylin (blue nuclear staining). (B) Comparison of the immunoreactivity score of GPER1 between samples recovered at initial diagnosis and during recurrence. The horizontal lines and error bars represent the means of immunoreactivity scores ± SEM, respectively. NS, not significant. (C) Pearson correlation analysis between GPER1 immunoreactivity score and tumor size (r = −0.38; P = 0.0431). Each dot represents the data collected from one patient.
