Implication

Findings demonstrate improved ineffective erythropoiesis in diamond blackfan anemia models, indicating mitapivat may affect cell death mechanisms and metabolic pathways.

Key Points

The study investigates the role of mitapivat in erythropoiesis within models of diamond blackfan anemia.
Generated conditional mouse models for DBA features using Rps19 and Rpl5 haploinsufficient mice.
Assessed proliferation and erythroid differentiation of cultured fetal liver cKit+ cells.
Analyzed cell death mechanisms including apoptosis and ferroptosis in haploinsufficient models.
Rpl5-haploinsufficient cells showed impaired proliferation and reduced RBC differentiation compared to controls.
Mitapivat treatment exhibited a trend toward improved cell counts and minor differentiation in Rpl5 haploinsufficient cells.
Distinct mechanisms of cell death were identified between Rps19 and Rpl5 haploinsufficient models.
