Thrombus formation is increased under conditions of hypoxia in animal models of thrombosis and in human populations, but current therapies for thrombosis do not directly target hypoxia-responsive signaling pathways. The vascular response to hypoxia is controlled primarily by the hypoxia-inducible transcription factors (HIFs), whose target genes include several factors that regulate thrombus formation. In this article, we review the HIF-dependent and HIF-independent signaling pathways that regulate thrombus formation under hypoxic conditions. A better understanding of hypoxia-induced thrombus formation could lead to the development of novel prophylactic therapies for thrombosis.
