abstract：:Gadd45a has been involved in DNA damage response and in many malignancies, including leukemia. However, the function of Gadd45a in hematopoietic stem cells (HSCs) remains unknown. Here, we reported that Gadd45a-deficient (Gadd45a(-/-)) mice showed a normal hematologic phenotype under homeostatic conditions. However, f...
