Identification of the molecular targets of Orm1 in regenerating mouse liver

To identify the molecular targets of orosomucoid (Orm1) during liver regeneration, GeneChip analysis was performed at 48 h after partial hepatectomy (PH) in regenerating mouse liver treated with siControl or siOrm. A total of 180 differentially expressed genes in Orm1 konckdown mouse liver by comparing with siControl were identified with a fold change more than 2. Then, pathway analysis performed on the altered gene expression profiles using Ingenuity Pathways Analysis (IPA) program revealed that cell cycle, Toll-like receptor and TGF-beta receptor signaling pathways were under control of Orm1 in regenerating mouse livers.
