Fig. 1From: IGF1 gene is epigenetically activated in preterm infants with intrauterine growth restrictionThe IGF1 gene promoters (P1 and P2). Broken arrows show the transcription start site (TSS) of each promoter. The six analyzed CG sites are shown with their locations on the chromosome. CGs are denominated according to their distance from the P2 promoter major TSSBack to article page
