HRI Protects Erythroid Precursors in iron deficiency and beta-Thalassemia by Maintaining GATA-1 and Fog-1 Expression

ABSTRACT: Heme-regulated eIF2α kinase (HRI) is essential for the survival of erythroid precursors in iron and heme deficiency and it also plays a protective role in red blood cell diseases of erythroid protoporphyria and β-thalassemia. In this study, we demonstrated for the first time the impairment of GATA-1 and Fog-1 expressions in iron deficiency and the impairment of GATA-1 expression in β-thalassemia. Furthermore, HRI is necessary to maintain the GATA-1/Fog-1 induced functions in erythroid differentiation, cell cycle and cell survival by sustaining both expressions of GATA-1 and Fog-1 in iron deficiency and in β-thalassemia. Keywords: Genetic modification

Domain-focused CRISPR-screen identifies HRI as a fetal hemoglobin regulator in human erythroid cells

Project description:Increasing fetal hemoglobin (HbF) levels in adult red blood cells provides clinical benefit to patients with sickle cell disease and some forms of beta-thalassemia. To identify potentially druggable HbF regulators in adult human erythroid cells, we employed a protein kinase-domain focused CRISPR/Cas9-based genetic screen with a newly optimized sgRNA scaffold. The screen uncovered the heme-regulated inhibitor HRI (also known as EIF2AK1), an erythroid-specific kinase that controls protein translation, as an HbF repressor. HRI depletion markedly increased HbF production in a specific manner and reduced sickling in cultured erythroid cells. Diminished expression of the HbF repressor BCL11A accounted in large part for the effects of HRI depletion. Taken together, these results suggest HRI as a potential therapeutic target for hemoglobinopathies.

Iron and Heme Coordinate Erythropoiesis through HRI-Mediated Regulation of Protein Translation and Gene Expression

Project description:Iron and heme play central roles in red blood cell production. However, the mechanisms by which iron and heme levels coordinate erythropoiesis remain incompletely understood. HRI is a heme-regulated kinase that controls translation by phosphorylating eIF2a. Here, we investigate the global impact of iron, heme and HRI on protein translation in vivo in murine primary erythroblasts using ribosome profiling. By defining the underlying changes in translation during iron and HRI deficiencies, we validate known regulators of this process, including Atf4, and identify novel pathways such as co-regulation of ribosomal protein mRNA translation. Surprisingly, we found that heme and HRI pathways, but not iron-regulated pathways, mediate the major protein translational and transcriptional responses to iron deficiency in erythroblasts in vivo and thereby identify previously unappreciated regulators of erythropoiesis. Our genome-wide study uncovers the major impact of the HRI-mediated integrated stress response for the adaptation to iron deficiency anemia.

GATA-1 and heme regulate the erythroid cell transcriptome.

Project description:Alas2 gene encodes the rate-limiting enzyme in heme biosynthesis. CRISPR/Cas9-mediated ablation of two Alas2 intronic cis-elements strongly reduced GATA-1-induced Alas2 transcription, heme biosynthesis, and GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing Alas2 function in Alas2 cis-element-mutant (double mutant) cells by providing its catalytic product 5-aminolevulinic acid (5-ALA) rescued heme biosynthesis and the GATA-1-dependent genetic network. We discovered a GATA factor- and heme-dependent circuit that establishes the erythroid cell transcriptome. G1E-ER-GATA-1 WT and double mutant cells were examined. Untreated WT, beta-estradiol-treated WT, beta-estradiol-treated double-mutant, and beta-estradiol/5-ALA-treated double-mutant cells were subjected to RNA-seq.

ChIP seq for GATA-1 and HDAC1 in G1E cells with wild type GATA-1 or mutant

Project description:The transcription factor GATA-1 is essential for erythroid and megakaryocytic cell differentiation and maturation. Previous reports show that GATA-1 is modulated through acetylation modification and through FOG-1 mediated indirect intereaction with HDAC1/2 containing NuRD corepressor complexes. In this study, we found that NuRD does not deacetylate GATA-1. However, HDAC1 alone can efficiently deacetylates GATA-1 and the direct interaction of HDAC1 and GATA-1 is required for the deacetylation. Two arginines within GATA-1 linker region are important for this interaction and arginine to alanine mutations (2RA mutant) largely reduces GATA-1 binding to HDAC1 in FOG-1 independent manner. GATA-1 2RA mutant were then introduced into G1E cells, a GATA-1-null erythroid progenitor cells. The 2RA mutant is acetylated but fails to induce erythroid differentiation. Gene expression analysis shows that GATA-1 2RA mutant affects GATA-1 function in both GATA-1 activated and repressed genes. The gene expression pattern partially overlap with gene expression profile of GATA-1V205M, a GATA-1 mutant with defective FOG-1 binding. ChIP-seq analysis further reveal that 2RA mutation largely reduced GATA-1 chromatin binding, most profoundly at gene promoter regions. HDAC1 recruitment on those promoters are also strongly reduced. These results revealed that GATA-1 recruits HDAC1 to GATA-1 regulated gene promoters and HDAC1 is required for GATA-1 mediated transcription regulation.

Protemic characterisation of the β-thalassemia erythroid cells from immortalised cell lines

Project description:β-thalassemia cell lines were generated via CRISPR-Cas9 genome editing of Bristol Erythroid Line Adult (BEL-A) and differentiated to the basophilic and polychromatic erythroid cell stage. TMT comparative proteomics was then performed on stage matched WT and β-thalassemia cells isolated by FACS.

Genome-wide analysis of the role of FOG-1 in GATA-1 chromatin occupancy

Project description:We report ChIP-Seq data for GATA-1 and the FOG-binding mutant of GATA-1 (GATA-1^V205G) in G1ME cells, a Gata1-null cell line with both erythroid and megakaryocytic differentiation potential. We introduced HA-tagged GATA-1 or V205G into G1ME cells via retroviral transduction. The cells were crosslinked at 48h post-transduction, and an HA antibody was used for chromatin immunoprecipitation (ChIP). ChIP and input samples were sequenced on Illumina GAII high-throughput sequencer. The data reveal GATA-1-specific and V205G-specific bidning sites, indicating that FOG-1 both faacilitates and prohibits GATA-1 chromatin occupancy in a context-dependent manner. Examinaton of chromatin occupancy of GATA-1 anda FOG-binding mutant of GATA-1 in G1ME cells cultured in TPO.

ATAC-seq reveals GATA-1- and heme-dependent chromatin targeting in erythroid cells.

Project description:CRISPR/Cas9-mediated ablation of two Alas2 intronic cis-elements in G1E-ER-GATA1 cells strongly reduced GATA-1-induced Alas2 transcription, heme biosynthesis, and GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing Alas2 function in Alas2 cis-element-mutant (double mutant) cells by providing its catalytic product 5-aminolevulinic acid (5-ALA) rescued heme biosynthesis and a subset of GATA-1-dependent genetic network. Using the same system, we discovered a GATA-1- and heme-dependent circuit that regulates chromatin accessibility during erythroid maturation.
