Table 2 The placenta GLUT1, GLUT3 and HIF-1α gene expressions between appropriate for gestational age (AGA) and fetal growth restriction (FGR) twin in the 15 monochorionic twins with selective FGR evaluated by gene expression ratio

From: Placental glucose transporter 1 and 3 gene expression in Monochorionic twin pregnancies with selective fetal growth restriction

  gene expression ratio P value
GLUT1 0.97 ± 0.52 0.81
GLUT3 1.42 ± 0.90 0.09
HIF-1α 1.20 ± 0.56 0.18
  1. P values were calculated by one sample t test and the test value was set as 1.0
  2. The placental GLUT1, GLUT3 and HIF-1α gene expression ratios for the two placental territories in a twin pair is presented as the fold changes between the two fetuses in monochorionic twins: (relative GLUTs (HIF-1α) expression levels of the selective FGR twin)/ (relative GLUTs (HIF-1α) expression levels of the AGA twin)
  3. FGR fetal intrauterine growth restriction, AGA appropriate for gestational age
