Interferon Regulatory Factor-8 Is Indispensable for the Expression of Promyelocytic Leukemia and the Formation of Nuclear Bodies in Myeloid Cells

Abstract excerpt

Interferon (IFN) regulatory factor-8 (IRF-8), previously known as ICSBP, is a myeloid cell essential transcription factor. Mice with null mutation in IRF-8 are defective in the ability of myeloid progenitor cells to mature toward macrophage lineage. Accordingly, these mice develop chronic myelogenous leukemia (CML). We demonstrate here that IRF-8 is an obligatory regulator of the promyelocytic leukemia (PML) gene...
