Increased Slc2a1 (also known as Glut-1) expression (the main glucose transporter across the plasma membrane) was detected by Lane and coworkers in the liver of newborn IUGR rats and normalized after the neonatal period, suggesting a transient adaptive response to the limited blood provision during the fetal period (Lane et al. 1999). This evidence concerns the gene SLC2A1 and fetal growth restriction.
