WebJan 7, 2024 · The IFITM1 gene enhancer was analyzed by chromatin immunoprecipitation (ChIP) sequencing, ChIP-to-PCR, luciferase reporter assays, and qRT-PCR for enhancer RNAs (eRNAs). Results RNA-seq confirmed IFITM1 as an LPS-stimulated gene, and RNAi demonstrated its importance for the LPS-stimulated migration. WebJAK2 and Irf1 genes are upregulated in TNF-α and IFN-γ treated mouse macrophages, as well as in severe COVID-19 patients. Disruption of this signaling pathway by deletion of Irf1 or Stat1 protects mouse macrophages from TNF-α- and IFN-γ- induced cell death, as well as induced holopsia deletion in the absence of Irf1.

Macrophages were treated for 3 h with IFN-α or LPS ( n = 4). b BMDMs were transfected with either an siRNA directed against Irf1 or a control siRNA against GFP .
WebWe hypothesize that our methodology will enable the efficient identification of IRF-specific and pan-IRF inhibitors that can be used for the treatment of IRF-dependent disorders and malignancies. Introduction In 1988 the first interferon regulatory factor (IRF) was identified and named IRF1 ( 1, 2 ). WebSep 1, 2024 · (E) IRF1 binding to the CIIta promoter at 4 h was not affected by SfA. Macrophages were incubated for 1 h with medium or SfA and then IFN-γ was added for 4 h, and the in vivo binding of IRF1 to CIIta promoter IV was determined by chromatin immunoprecipitation. Each graph represents mean ± SD of three independent experiments.
