Here we investigated TR activity on red cell gene expression using a genome-wide approach with DNA microarrays and identified TR target genes. Ligand-activated TR effectively accelerated red cell progenitor differentiation in vitro concomitantly with inducing growth arrest. We demonstrate that activated TR induced specific gene expression patterns of up- or down-regulated genes, including distinct clusters associated with accelerated differentiation in response to treatment. Mining for T3 induced genes identified BTEB1 and GAR22 as TR target genes. BTEB1 is a known TR target gene while GAR22, initially identified as a putative tumor suppressor, represents a novel TR target gene. We demonstrate that ectopic GAR22 expression in red cell progenitors lengthens the cell cycle and causes growth inhibition, but leaves red cell gene expression unaffected.
