Postnatal maturation of rat mesenteric arterial (MA) smooth muscle gene expression. RNA was isolated from postnatal day (PND)12–42 and adult (10 wk) rat MA. A: representative gel of PCR products that contain (E24+) or lack (E24-) the 31-nt Mypt1 alternative exon 24 (E24) and graphed as %Mypt1 E24-. B–D: mRNAs were measured by qPCR using TaqMan probes normalized to cyclophilin A and reported as fold change vs. PND12 values. n = 3/PND. All data are expressed as means ± SE. MLCK, myosin light chain kinase.
