Abstract
In a recent review we addressed the role of the transcription factor NF-κB, in shaping the cancer microenvironment. NF-κB, which interacts with chromatin modulators by cell-specific dynamics, controls cell interactions during inflammation, and its abnormal feedback regulation is implicated in cancer. Inflammation normally reprograms cells through changes in key topological elements of chromosomal DNA. As a result, inflammation overrides cell phenotype: initially, reprogramming cell function halts processes that impede the response of a damaged tissue to the cause of the harm, and eventually, late reprogramming of cells will replenish tissue structure and restore function. Each cell type provides a distinct resource for restoration of tissue integrity, tissue function, and for replenishment of the responsiveness of the immune system. Modulators of NF-κB transcriptional activity alter key aspects of gene expression and tissue integrity. NF-κB network alterations confer transcriptional plasticity to cancer
