Lipin-1 and lipin-2 expression levels were measured using Western blot and real-time quantitative PCR.<h4>Results</h4>The IUGR group exhibited significantly higher mRNA and protein expression levels of lipin-1 and lipin-2 compared to the control group at days 21, 56, and 84 after birth. This evidence concerns the gene LPIN2 and fetal growth restriction.
