title: Mapping of a DNA sequence that down-regulates the expression of an interferon-induced gene.
abstract: Recently, an interferon response element (IRE) of approximately 24 bp has been identified by Reich et al. (7) that allows certain genes to be actively transcribed by type I interferons (IFNs). The transcription of several IFN-induced genes in some cells (human fibroblasts and melanoma cells) is inhibited by long-term exposure to IFN. This process requires the synthesis of a new protein(s). Evidence is presented that this same IRE contains the information necessary for long-term IFN treatment to down-regulate the transcription of those genes whose expression it initially activates.
