Interferon 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 کاملHuman cancer cells respond to cytosolic nucleic acids via enhanced production of interferon-β and apoptosis
The innate immune system utilizes pattern-recognition receptors (PRRs) to detect the invasion of pathogens and initiate host antimicrobial responses. Recently, it was reported that human cancer cells also expressed PRRs, and responded to cytosolic nucleic acids via the production of type I interferon and apoptosis in susceptible cells. However, the definite nucleic acids senses in different can...
متن کاملIRF 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...
