IRF 1 ( interferon regulatory factor 1 )
Hugo: IRF1 Other names: IRF-1; MAR Location: 5q23.3 Note: Interferon regulatory factor 1 belongs to a family of transcription factors described for their role in regulating type I and type II interferons. Specifically, IRF1 has been identified as an activator of interferon alpha and beta transcription. Furthermore, it has been shown to play a role in the regulation of tumour suppression. IRF1 l...
متن کاملInterferon-γ Upregulates Expression of IFP35 Gene in HeLa Cells via Interferon Regulatory Factor-1
BACKGROUND Interferon-induced 35-kDa protein (IFP35) plays important roles in antiviral defense and the progression of some skin cancer diseases. It can be induced by interferon-γ (IFN-γ) in multiple human cells. However, the mechanisms by which IFN-γ contributes to IFP35 induction remain to be elucidated. METHODS/PRINCIPAL FINDINGS We identified the transcription start sites of IFP35 by 5' r...
متن کاملInterferon Regulatory Factor (Irf)-1 and Irf-2 Regulate Interferon γ–Dependent Cyclooxygenase 2 Expression
Cyclooxygenases (Cox) are rate-limiting enzymes that initiate the conversion of arachidonic acid to prostanoids. Cox-2 is the inducible isoform that is upregulated by proinflammatory agents, initiating many prostanoid-mediated pathological aspects of inflammation. In this study, we demonstrate that interferon (IFN)-gamma alone or in synergy with lipopolysaccharide (LPS) or interleukin 1alpha in...
متن کاملInterferon-γ-induced upregulation of immunoproteasome subunit assembly overcomes bortezomib resistance in human hematological cell lines
BACKGROUND Despite encouraging results with the proteasome inhibitor bortezomib in the treatment of hematologic malignancies, emergence of resistance can limit its efficacy, hence calling for novel strategies to overcome bortezomib-resistance. We previously showed that bortezomib-resistant human leukemia cell lines expressed significantly lower levels of immunoproteasome at the expense of const...
متن کاملThe transcription factor interferon regulatory factor-1 mediates liver damage during ischemia-reperfusion injury.
Hepatic ischemia occurs in the settings of trauma, transplantation, and elective liver resections. The initiating events that account for local organ damage are only partially understood. Interferon (IFN) regulatory factor-1 (IRF-1) is a transcription factor that regulates the expression of a number of genes involved in both innate and acquired immunity; however, its function in liver injury is...
