| ABSTRACT Objective：To clone the luciferase reporter gene and construct promoter region from human G0S2 gene. Methods：A
region containing human G0S2 gene promoter was obtained by PCR amplification from 293A cells, and the segment was cloned into the
pGL3-Basic vector and transformed into , which was verified by endonuclease, PCR amplification and direct sequencing. The final
construct (pGL3-G0S2-Promoter) was transferred into VSMC (vascular smooth muscle cells), and the luciferase activity was measured.
Results：The insert and surrounding regions in pGL3-G0S2-Promoter plasmid were confirmed. There was significant promoter activity for
pGL3-G0S2-Promoter vector (P<0.05).Conclusion：Luciferase reporter plasmid pGL3-G0S2-Promoter containing G0S2 promoter can
be built successfully. It will be used to study the transcriptional regulation of G0S2 gene. |
