BCL6 and endometrioid adenocarcinoma: The LINC00152 and BCL6 protein were expressed predominantly in the nucleus in the ovarian high-grade serous and endometrioid carcinoma tissues (Figure 5A); however, the sensitive immunofluorescence showed that there were still residual amounts of LINC00152 and BCL6 proteins localized in the cytoplasm (Figure 5B).
