Hypoxia inducible factor-1α (HIF-1α) is a critical transcription factor for the hypoxic response, angiogenesis, normal hematopoietic stem cell regulation, and cancer development. Importantly, HIF-1α is also a key regulator for immune cell activation. In order to determine whether HIF-1α is sufficient for developing MDS phenotypes, we generated blood specific inducible HIF-1α transgenic mice. Using Vav1-Cre/Rosa26-loxP-Stop-loxP (LSL) rtTA driver, stable HIF-1α can be induced in a doxycycline administration dependent manner. After induction, HIF-1α-induced mice developed thrombocytopenia, leukocytopenia, macrocytic anemia, and multi-lineage dysplasia. We also found activation of both innate and adaptive immunity in HIF-1α- induced mice compared to those from control mice. Taken together, these data suggest that HIF-1α is sufficient to trigger a variety of key MDS features
