We have isolated a novel gene, rig (rat insulinoma gene) from rat insulinomas. In the present study, rig was found to be expressed in rat regenerating liver and in primary cultured rat hepatocytes. The level of rig mRNA was increased at the proliferative phase of liver regeneration. In synchronously cultured hepatocytes, the rig mRNA level was elevated at the G1 phase of the cell cycle and the rig-protein was accumulated in the nuclei during the S phase. These results indicated that rig could be involved in a more general way in growth or cell replication.
