Data on the role of miR-144 in regulating fetal hemoglobin production in retinal pigmented epithelial cells

Research output: Contribution to journalArticle

Abstract

The data presented in this article are connected to our related article entitled “Inhibiting microRNA-144 potentiates Nrf2-dependent antioxidant signaling in retinal pigmented epithelial cells (RPE) and protects against oxidative stress-induced outer retinal degeneration” [1] where, we have shown that miR-144 induces oxidative stress in RPE cells by targeting Nrf2 expression. Previous studies from our laboratory have shown that like erythroid cells, RPE cells express α, β and γ-globin and produce hemoglobin locally in retina. Further, the ability to therapeutically reactivate fetal hemoglobin production in these cells, a strategy of high potential benefit in the treatment of complications of sickle cell disease, including retinopathy, is impacted by Nrf2-mediated signaling [2,3]. Studies by others [4,5] provide compelling evidence of a regulatory role for miR-144 and Nrf2 in fetal hemoglobin production in erythroid cells. Our current work confirms this finding in human RPE. We additionally show that miR-144-mediated regulation of fetal hemoglobin production in RPE cells is independent of kruppel like factor 1 (KLF-1). This supports the plausibility that in RPE, hemoglobin, particularly fetal hemoglobin, may be important for functions other than oxygen transport (e.g., antioxidant defense). Indeed, our new data on miR-144 in RPE supports strongly the potential mechanistic between fetal hemoglobin production and the regulation of oxidative stress in this cell type [1].
