NFKB1 and neoplasm: The immunohistochemical and immunofluorescence data have revealed that the expression levels of EGFR, Ser473-pAkt, NF-κB p65 and MIC-1 proteins were significantly enhanced in the same subset of 76 cases of prostatic adenocarcinoma specimens during the disease progression and these biomarkers were expressed in a small subpopulation of CD133+ PC cells and the bulk tumor mass of CD133− PC cells.
