(A) Expression levels of NPAS2 in EC (A) RT-qPCR detection of NPAS2 in EC and in adjacent normal tissue. Data are expressed as the mean±SD. ***P<0.0001 (B) Immunohistochemical analysis of NPAS2 in normal and endometrial cancer tissues. Representative images of NPAS2 staining in benign and epithelial ovarian cancer tissues are shown. The positive staining of NPAS2 is shown in brown color, and the cell nuclei were counterstained with hematoxylin. Original magnification, 400× (right panels), Scale bars, 50 μm.
