Mice lacking E‐prostanoid 4 receptor in vascular smooth muscle cells have reduced baseline blood pressure (BP). A, The mean arterial pressures (MAPs) during baseline and the high‐salt (HS) feeding period were significantly lower in smooth muscle knockout (SMKO) mice compared with control. B, The MAP change from low‐salt (LS) to HS feeding was similar between the 2 groups. n=10 to 11 per group. Data are expressed as mean±SEM. NS indicates normal salt; N.S., not significant. *P<0.05 vs control.
