Genistein, which inactivated NF-kB and caused transcriptional inactivation of Bcl-XL and Bcl-2, could be combined with (−)-gossypol to inactivate the function of Bcl-XL and Bcl-2 and then enhanced the death of pancreatic cancer cells [45]. This evidence concerns the gene NFKB1 and pancreatic neoplasm.
