Abstract

XBP-1 is a CREB/ATF family transcription factor highly expressed in hepatocellular carcinomas. Here we report that XBP-1 is essential for liver growth. Mice lacking XBP-1 displayed hypoplastic fetal livers, whose reduced hematopoiesis resulted in death from anemia. Nevertheless, XBP-1-deficient hematopoietic progenitors had no cell-autonomous defect in differentiation. Rather, hepatocyte development itself was severely impaired by two measures: diminished growth rate and prominent apoptosis. Specific target genes of XBP-1 in the liver were identified as αFP, which may be a regulator of hepatocyte growth, and three acute phase protein family members. Therefore, XBP-1 is a transcription factor essential for hepatocyte growth.
