Famciclovir leads to failure of hematopoiesis, but may have the benefit of relieving myeloid expansion in MDS-like zebrafish

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...
