Multi-Omics Analysis in β-Thalassemia Using an HBB Gene-Knockout Human Erythroid Progenitor Cell Model.

ABSTRACT: β-thalassemia is a hematologic disease that may be associated with significant morbidity and mortality. Increased expression of HBG1/2 can ameliorate the severity of β-thalassemia. Compared to the unaffected population, some β-thalassemia patients display elevated HBG1/2 expression levels in their red blood cells. However, the magnitude of up-regulation does not reach the threshold of self-healing, and thus, the molecular mechanism underlying HBG1/2 expression in the context of HBB-deficiency requires further elucidation. Here, we performed a multi-omics study examining chromatin accessibility, transcriptome, proteome, and phosphorylation patterns in the HBB homozygous knockout of the HUDEP2 cell line (HBB-KO). We found that up-regulation of HBG1/2
