摘要: Thyroid hormone and its cognate receptor (TR) have been implicated in the production of red blood cells. Here, we show mice deficient for TRalpha compromised fetal adult erythropoiesis. Erythroid progenitor numbers were significantly reduced TRalpha(-/-) livers, transit through final stages maturation was impeded. In addition, immortalized erythroblasts displayed increased apoptosis capacity proliferation differentiation. Adult had lower hematocrit levels, elevated glucocorticoid an altered stress erythropoiesis response to hemolytic anemia. Most animals contained markedly their spleens. Strikingly, 20% failed elicit a recovered very poorly from We conclude that underlying erythroid defect exists mice, demon-strating importance compartment.
