Description
BTB and CNC homology 1 (BACH1) is a heme-binding transcription factor repressing the transcription from a subset of MAF recognition elements (MAREs) at low intracellular heme levels. Upon heme binding, BACH1 is released from the MAREs, resulting in increased expression of antioxidant response genes. To systematically address the gene regulatory networks involving BACH1, we performed knock-down of BACH1 in HEK 293T cells using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays.
