PG - 1465-1473 LID - 10.13345/j.cjb.160185 [doi] AB - To quantify the transcriptional activity of NF-kappaB and to screen drugs related to the regulation of NF-kappaB activation, we constructed a recombinant plasmid through deleting the original CMV promoter of retrovirus vector pQCXIP and inserting the NF-kappaB enhancer and NanoLuc luciferase sequence into the vector. Then, using the recombinant plasmid we constructed a cell line in which the expression of NanoLuc luciferase (NLuc) was regulated by NF-kappaB. The inserted sequences were verified by restriction endonuclease digestion and sequencing. Tumor necrosis factor-alpha (TNF-alpha), an NF-kappaB activator, acted on the constructed NLuc cell line and leaded to the specific luciferase reaction. The luciferase reaction showed a fine time and dose dependence to the TNF-alpha stimulation, indicating the successful construction of the NF-kappaB regulated NLuc-expressing cell line. Besides, the NF-kappaB inhibitor, triptolide, reduced the expression of NLuc in a dose-dependent way. The constructed reporter system in this study could be applied in the quantification of the NF-kappaB transcriptional activity and in the NF-kappaB regulation-related drug screening.
