Figure 8 shows the immunolocalization of AR in different regions of the tumor. Expression of the receptor was localized both in the cell nucleus and in the cytoplasm of the cells. The highest expression of the receptor was observed in the actively dividing part of the tumor, i.e., the enhancing tumor region (Figure 8B). In the peritumoral area (Figure 8C), receptor expression was lower and was mainly localized in the cell nuclei. The tumor core (Figure 8A) showed the lowest expression of the receptor. The gene discussed is AR; the disease is neoplasm.
