Our results suggest that PATZ1 and PP4R2 provide negative feedback on IKK/NF-κB signaling to prevent cancer cells from over-stimulation from cellular stimuli; a decline in PATZ1 and PP4R2 is functionally associated with cancer migration/invasion and agents enhancing PATZ1 and PP4R2 are worth exploring to prevent invasion/metastasis of lung cancers. This evidence concerns the gene PATZ1 and lung cancer.
