Newborn and adult mRNA expression of regions of IGF1

Treatment	Age	IGF1 Exon 1	IGF1A	IGF1 Exon 2	IGF1B
AdLib	Newborn	100 ± 8.8	100 ± 22.8	100 ± 9.9	100 ± 9.0
FR	Newborn	84.3 ± 25.8	211.9 ± 98.5	64.8 ± 17.1	104 ± 30.7
AdLib/AdLib	Adult	100 ± 9.6	100 ± 6.9	100 ± 8.8	100 ± 5.0
FR/AdLib	Adult	149.3 ± 6.6	133.7 ± 5.3	146 ± 7.7	164.9 ± 6.3
FR/FR	Adult	74.6 ± 8.3	99.3 ± 6.8	86.3 ± 8.3	146.8 ± 21.0

Values are means ± SE. mRNA expression of regions of IGF1 relative to GADPH is expressed as a percentage of expression levels of controls for the age group. The results are from newborns at 1 day of age of ad libitum-fed animals (AdLib, controls) vs. food-restricted pregnancy animals (FR), adults at 9 mo of age of AdLib/AdLib (control) vs. FR/AdLib (food-restricted pregnancy and AdLib lactation), and FR/FR (food-restricted pregnancy and lactation). * and † Differences between adult treatment groups, P < 0.05.
