p-p38 and caspase-8 expression in ccRCC. A): (p-p38 X400). p-p38 nuclear expression in few malignant cells in a grade 1 ccRCC. B): (p-p38 X400). High p-p38 nuclear expression from the majority of neoplastic cells in a grade 4 ccRCC. C): (caspase-8 X400). Strong cytoplasmic and nuclear expression of caspase-8 in a grade 1 ccRCC. D): (caspase-8 X400). Weak cytoplasmic as well as nuclear expression of caspase-8 in a grade 4 ccRCC. ccRCC: clear cell renal cell carcinoma.
