Popis: This study was performed to examine the effects of the calcium channel blockers, nifedipine, amlodipine, diltiazem, and verapamil on the activation of the transcription factor NF-kappaB. A549 cells, a human epithelium-like lung carcinoma cell line, were transfected with the NF-kappaB reporter plasmid, which contains the luciferase gene driven by promoters containing a TATA element and 5 copies of the kappaB cis-acting element, and co-transfected with 0.2 microg of pSV2neo vector using LipofectAMINE. Nifedipine significantly decreased the expression of luciferase protein stimulated with IL-1beta (1 ng/mL) compared with controls: 80+/-4% at 3 micromol/L, 47+/-2% at 10 micromol/L and 30+/-2% at 30 micromol/L (each, n=3, p
