ABSTRACT
Famciclovir (FCV) is an antiviral drug that is often utilized after bone marrow transplantation to prevent viral infection. Yet, its role in hematopoiesis is poorly understood. Here, by utilizing a zebrafish model, we found that FCV exposure led to hematopoietic failure by impairing the proliferation of hematopoietic stem and progenitor cell (HSPC) and inducing HSPC apoptosis. On the other hand, FCV treatment could effectively relieve myeloid malignancies in the c-mybhyper MDS-like fish model, and played a role not only in the embryonic stage but also in adult zebrafish. This study reveals that FCV functions as a double-edged sword, with hematotoxicity at a high level, but that appropriate FCV treatment may be beneficial for the treatment of MDS.
