NFKB1 and cancer: This review synthesizes current evidence that SFN regulates diverse cancer-relevant processes, including redox homeostasis, cell-cycle progression, apoptosis, autophagy and epigenetic remodeling, largely through coordinated effects on transcriptional (for example, Nrf2, MAPK, NF-κB and AP-1), post-transcriptional (microRNAs and messenger RNAs) and epigenetic (DNA methyltransferases and histone deacetylases) networks.
