expression of GST-tagged wild-type and mutant enzymes in Escherichia coli strain BL21(DE3), transfection of wild-type HO-1 cDNA or intracellular delivery of pure HO-1 protein into cultured NIH 3T3 cells results in activation of a 15-kb HO-1 promoter independently of HO activity, expression of an catalytically inactive HO-1 also results in promoter activation, HO-1-mediated promoter activation is regulated via the distal enhancers E1 and E2 | Rattus norvegicus |
