Abstract:

Objective To explore the effect of SETD4 (SET-domain containing protein 4) in IL-6 transcription in AML12 cells (murine hepatocyte line) stimulated with LPS. Methods Recombination plasmids encoding SETD4 or IL-6 promoter luciferase were constructed and cotransfected into AML12 cells. After LPS stimulation, the luciferase activity of IL-6 promoter was detected by Dual-luciferase reporter assay system. The LPS-induced IL-6 mRNA in AML12 cells with SEDT4 over-expression was also measured. Results The plasmids of pcDNA3.0/HA-SETD4 and pGL3.0/IL-6 promoter were constructed successfully, evidenced by double restriction enzyme digestion identification and DNA sequencing. The results showed that SETD4 have no effect on luciferase activity when IL-6 promoter luciferase plasmid and SETD4 plasmid were cotransfected into the AML12 cells following LPS stimulation. Over-expression of SETD4 could up-regulate the LPS-induced IL-6 mRNA transcription in AML12 cells. Conclusion SETD4 expression plasmid and IL-6 promoter luciferase plasmid were constructed successfully. SETD4 may play a positive effect on LPS-induced IL-6 transcription in AML12 cells.
