Hematopoietic Tfr2 deletion enhances erythropoiesis and metabolic activity, improving glucose homeostasis in β-thalassemia models.

This research aims to explore how Tfr2 influences erythropoiesis and its effects on glucose metabolism.
Generated wt and Tfr2BMKO mice through bone marrow transplantation (BMT).
Conducted RNA-seq analysis of sorted erythroid precursors post-BMT.
Performed complete hematological and metabolic characterization after BMT.
Monitored blood glucose, body weight, and erythropoietic response after EPO treatment and Phenylhydrazine injections.
Tfr2BMKO mice showed increased erythropoiesis and RBC counts with systemic insulin-independent hypoglycemia.
RNA-seq analysis revealed upregulation of metabolic genes in Tfr2 deficient erythroblasts.
EPO treatment resulted in a 10% decline in blood glucose and increased RBC count.
Phenylhydrazine-induced erythropoiesis led to a 25% reduction in glycemia and body weight loss.

Tanzi et al. (2025) studied this question.
