The 3x-Bcl6 reporter construct has been described previously9 (link). Slc2a3, Slc2a1, P4ha2, Plod2 and Tpi1 reporter constructs were prepared by cloning the promoters of each gene into the pGL3-basic luciferase reporter construct (Promega). EL4 or A20 cells were co-transfected with the indicated expression vectors along with the promoter-reporter constructs as well as a CMV-renilla control plasmid to normalize for transfection efficiency. The samples were harvested 16–24 h post-transfection and then analyzed with the Dual-Luciferase Reporter system (Promega).
