Abstract

Background: Erythropoietin is required for erythrocyte production and stimulates erythroid gene expression including EPO-R. Results: TAL1 induction promotes accessibility of EPO-R promoter to the GATA-1-TAL1-LMO2-LDB1 transcription activation complex to increase EPO-R expression. Conclusion: Forced TAL1 expression increases EPO-R and erythropoietin hypersensitivity in erythroid progenitors. Significance: Providing insight into the molecular link between TAL1 and erythropoietin activity.
