A plasmid containing the mouse MCP-1 promoter driving luciferase (pMCP-Luc) was constructed from pGL3-basic (Promega, Madison, WI) and a PCR-generated MCP-1 promoter fragment. A proofreading competent Taq reagent (AccuTaq, Sigma) was used to ensure high fidelity PCR. 1.2 kb of the MCP-1 promoter (GenBank Accession no. U12470) was obtained by PCR of C57BL/6 mouse DNA with the following primers:
5′–TCATGTATATGGCTTTCCAGGTCT–3′ (sense strand, distal to transcription start)
5′–TGCACTTCTGGCTGCTCTGAG GCA–3′ (antisense strand, proximal to transcription start)
The PCR product terminates 28-bp downstream of the MCP-1 TATA site. XmaI and XhoI sites were added to the MCP-1 promoter by a second round of PCR with the primers:
and XmaI and XhoI were used to clone the MCP-1 promoter fragment into pGL3-basic.
For the construction of the MCP-1 mutant promoter, the BCL-6 site was mutated by a two step PCR–based strategy using the above flanking primers and the following complementary primers to mutate the BCL-6 site:
5′–TGTTT[AA]AGGAAGTGGAAGAGAGA–3′ (mutated bases are in brackets)
The mutant promoter was cloned into pGL3 via XhoI and XmaI. The wild-type and mutant MCP-1 promoter sequences were verified by sequencing.
