Project description:We identified differentially expressed genes in response to single and double ligand treatments (LPS, IFG, 2MA, LPS plus 2MA, and LPS plus IFG). The majority of the regulated transcripts responded additively to dual ligand treatment. However, a significant fraction responded in a non-additive fashion. Several cytokines showing non-additive transcriptional responses to dual ligand treatment also showed non-additive protein production/secretion responses in separate experiments. Many of the genes with non-additive responses to LPS plus 2MA showed enhanced responses and encoded pro-inflammatory proteins. On the other hand, LPS plus IFG appeared to induce both non-additive enhancement and non-additive attenuation of gene expression. The affected genes were associated with a variety of biological functions. These experiments reveal both dependent and independent regulatory pathways and further analyses may point out the specific nature of the regulatory interactions.

Project description:Melatonin is a powerful anti-inflammatory agent and antioxidant. To explore specific anti-inflammatory mechanisms, LPS was used to intervene in RAW 264.7 cells to construct an inflammation model. Then, cells were pretreated with melatonin at concentrations of 10-3M to 10-7M, respectively. The above cells were subjected to DRUG-seq sequencing to explore the specific mechanism of melatonin anti-inflammation.

Project description:Immunoresponsive gene 1 (IRG1) is one of the highest induced genes in macrophages under pro-inflammatory conditions and its function has been recently described: it codes for immune-responsive gene 1 protein/cis-aconitic acid decarboxylase (IRG1/CAD), an enzyme catalyzing the production of itaconic acid from cis-aconitic acid, a tricarboxylic acid (TCA) cycle intermediate. Itaconic acid possesses specific antimicrobial properties inhibiting isocitrate lyase, the first enzyme of the glyoxylate shunt, an anaplerotic pathway that bypasses the TCA cycle and enables bacteria to survive on limited carbon conditions. To elucidate the mechanisms underlying itaconic acid production through IRG1 induction in macrophages, we examined the transcriptional regulation of IRG1. Using a combination of literature information, transcription factor prediction models and genome-wide expression arrays, we inferred the regulatory network of IRG1 in mouse and human macrophages. 3 unstimulated (Control) and 3 LPS-stimulated RAW 264.7 macrophages
