We aimed to analyze potential alterations in total methylation and in p66Shc activation in placental tissues from women delivering intrauterine growth restricted neonates (IUGR) versus appropriate for gestational age (AGA) and small for gestational age (SGA) neonates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>DNA methylation of the p66Shc promoter and of long interspersed nuclear elements (LINE\u20101), as a marker for total methylation, was quantified by automatic pyrosequencing in 15 IUGR, 25 AGA and 15 SGA placentas. Placental gene expression of p66Shc was determined by TaqMan real\u2010time polymerase chain reaction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No significant difference was found for LINE\u20101 methylation between IUGR, AGA and SGA newborns. DNA methylation of the p66Shc promoter was significantly decreased in the IUGR compared with the AGA group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001) and the SGA group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001).
