    A Study of the mRNA Level of IGF2 and H19 in Landrace and Lantang Swine

      Graphical Abstract
      • Abstract
    • In this study, the mRNA expression levels of imprinted gene IGF2 and H19 in Landrace and Lantang swine were investigated through real-time fluorescence quantitative PCR. The pigs were grouped according to growth traits. The relationships between mRNA expression levels with growth and reproductive traits were analyzed. The results showed the IGF2 mRNA expression levels of liver in the heavy birth body mass group was higher than that of the light birth body mass group. When 180 days old, the IGF2mRNA expression levels of fat in the thick sebum group was higher than that of the thin sebum group. The IGF2 mRNA expression levels of liver, muscle and stomach in 1 day old piglet were higher than those in other tissues. The H19 mRNA expression levels of kidney in 180 days old Landrace pig increased significantly.
