Abstract: The liver is a vital organ that plays a major role in metabolism and other functions in the body. In this study, researchers used microarray analyses to investigate the gene expression profile during the development of the liver in pigs (Suss crofa). Researchers identified various differentially expressed genes in the liver between the prenatal and postnatal stages. The upregulated genes in the prenatal liver were related to the cell cycle and developmental process. The genes that were upregulated in the postnatal liver were active in the immunological process. The study presented gene expression profiles of the porcine liver during the pre and post-natal stages which contribute to the understanding porcine liver development.
