NFKB1 and lung disorder: Afterwards, taking into account that mucin gene expression in lung disease is transcriptionally and post-transcriptionally regulated by inflammatory mediators [24] and P. aeruginosa LPS induces the expression of MUC2 gene via NF-κB [24], [25], we studied the effects of LPPPEI on MUC2 gene expression in LPS-stimulated mucoepidermoid carcinoma cells (NCI-H292).
