DNAH8 and fetal growth restriction: ATPase staining showed an obvious decrease (p < 0.05; Figure 2A,B) in the percentage of fast-fibers in the LT muscle of IUGR piglets, and RT-PCR results indicated that IUGR decreased (p < 0.05; Figure 2C) the mRNA expressions of MyHC IIx and MyHC IIb and elevated (p < 0.05; Figure 2C) the mRNA expression of MyHC I when compared with NBW piglets.
