Sook Young Lee and Su‐Mi Chung administered Neovastat (AE‐941) after establishing a mouse model of asthma, and they assessed a decrease in the expression of VEGF and HIF‐2α in lung tissues, concluding that Neovastat significantly attenuated the airway inflammation in asthmatic mice by inhibiting the expression of VEGF and HIF‐2α. This evidence concerns the gene EPAS1 and asthma.
