NO inhibits the transcription-resistant factor YY1, which results in the induction of the tumor expression of the proteins, Raf Kinase Inhibitor Protein (RKIP) and PTEN, the inhibition of the pro-survival Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-kB) and AKT pathways, and the upregulation of Fas and Death Receptor 5 (DR5) expression on tumor cells, thus reversing resistance [56]. This evidence concerns the gene AKT1 and neoplasm.
