Immunohistochemical expression of PIWIL1, PIWIL2, PIWIL3 and PIWIL4 in colon cancer and adjacent non-cancer tissue. In colon cancer tissue PIWIL1-4 expression was often stronger in the cytoplasm compared with adjacent non-cancer tissue (A, B, C, D). Adjacent non-cancer tissue is detected with very weak PIWIL1-4 expression in the cytoplasm (E, F, G, H). Magnifications: ×200.
