We found that NFKB1, a central actor of the IFNg pathway is activated in ccRCC, consistently with other reports (Zhang et al, 2018; Rodrigues et al, 2018) where it was also demonstrated to be regulated by the PI3K/AKT pathway (An & Rettig, 2007). Here, NFKB1 is linked to nonpapillary renal cell carcinoma.
