Loss of TRIM28 protein expression in TRIM28‐mutated Wilms' tumour. Top: immunohistochemical staining with anti‐KAP1 antibody (ab10484) in an epithelial Wilms' tumour (WT) of a 7‐month‐old boy with a somatic TRIM28 mutation showing absent nuclear staining in tumour cells, with retained expression of KAP1 in non‐tumoural cells. Bottom: retained expression of KAP1 in adjacent normal kidney tissue. The counterstaining with Mayer's haematoxylin (blue) appears more intense in the tumour, due to the fact that the tumour slice is slightly thicker and lacks KAP1 (brown) staining.
