Right ventricular systolic pressure (RVSP) of male wild-type (WT; n = 7) and soluble epoxide hydrolase knockout (sEH-KO; n = 7) mice under control condition and exposure of mice to hypoxia in the absence and presence of 10 µM 14,15-EEZE [an epoxyeicosatrienoic acid (EET) antagonist], respectively. *Significant difference from their controls, P < 0.05. #Significant difference from WT mice under hypoxia, P < 0.05. @Significant difference from sEH-KO mice under hypoxia, P < 0.05.
