mPRα and mPRβ were localized primarily to cell membranes, while mPRγ was localized in the cytoplasm and/or nucleus of normal endometrial tissue, while mPRα and mPRβ were detected at the cell membrane or in the cytoplasm, or both, while mPRγ was only localized in the cytoplasm of endometrial cancer tissue [37]. The gene discussed is PAQR8; the disease is endometrial cancer.
