Effects measured in mesenteric artery of starvation (30 min of glucose and O₂ deprivation) reported as “Fold-Control” or “Fold-PE” (see “Methods”) on the basal phosphorylation levels of MLC and the myosin phosphatase regulatory subunit MYPT1 (A), the AMPK substrates rhoA (A) and PLB (B), and on the level of active rhoA-GTP (C). PE = phenylephrine. Data are means ± SE, n = 4–7 for (A,C), and n = 3–4 for (B). For (A,C), ^*P < 0.05 compared to 1. For (B), ^*P < 0.025. ^*Over bracket indicates that bracketed groups are significantly different at P < 0.025.
