Project description:The aim of this experiment is to compare gene expression proflies of RAW264.7 cells trasnfected with non-targeting siRNA or siRNA against RUVBL2, in the presence or absence of LPS.
Project description:Translational profiling of RAW264.7 cells stimulated with LPS in the presence and absence of 125ng/ml mycolactone: polysomal and subpolysomal RNA isolated by sucrose gradient centrifugation to determine the effect of mycolactone on translation during a proinflammatory response
Project description:Low-intensity pulsed ultrasound (LIPUS) is a special type of low intensity ultrasound. In periodontal disease, LIPUS was applied as an adjuvant and non-invasive therapeutic treatment. While, the specific mechanism of LIPUS in the treatment of periodontal disease is not quite clear.RAW264.7 cells were induced to M1/M2 macrophage-like polarization by LPS/IL4. LIPUS was performed to stimulate RAW264.7 cells at an intensity of 45 mW/cm2, 25 min, interval 24 h, twice. The polyA mRNA sequencing of LPS induced RAW264.7 cells, LPS induced and LIPUS treated RAW264.7 cells were conducted.Our results suggested that LIPUS played an anti-inflammatory role by inhibiting LPS-induced M1 polarization of RAW264.7 cells in an Wnt2b/AXIN/β-catenin dependent way. LIPUS may inhibit inflammation in periodontal diseases by regulating macrophage differentiation, so as to play a therapeutic role in periodontal diseases.
Project description:We sought to characterize the genomic localization of the YEATS domain protein AF9 in the macrophage-like cell line RAW 264.7 +/- LPS stimulation and +/- sodium crotonate pretreatment. We performed chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-seq) for endogenous AF9 or for a FLAG-tagged AF9 transgene in RAW264.7 or a RAW264.7 cell line engineered to express FLAG-AF9, respectively.
Project description:Nuclear interaction studies by ChIP coupled with mass spectrometry identified the COMPASS/SETD1A complex as interaction partner of the glucocorticoid receptor (GR) in murine bone marrow-derived macrophages (BMDMs). Here, we profiled H3K4me1, H3K4me2 and H3K4me3 in wild-type and Setd1a hypermorphic (Setd1aDel/+) Raw264.7 cells after LPS and Dex+LPS stimulation by spike-in ChIP-Seq.
Project description:After stimulation of RAW264.7 cells with LPS and Harmine, high-throughput sequencing technology was used to explore the changes in the inflammation level of RAW cells and the enrichment of signaling pathways after LPS and Harmine treatment, and to find an interesting target pathway.
Project description:RAW264.7 cells were transfected with Synbindin siRNA for 48hours, then 100ng/ml LPS were treated cells for 4 hours. Before and after LPS stimulation, cells were collected and RNA were extracted for RNA-seq.
Project description:Unanticipated regulatory protein modifications can be discovered from the unbiased comprehensive analysis of biological systems using SAMPEI. To explore this idea, we sought to map protein modifications induced during mammalian cell differentiation, modeled by the response of mouse RAW264.7 macrophage cells to lipopolysaccharide (LPS), a potent inducer of macrophage activation and differentiation that involves extensive protein and metabolic signaling.
Project description:We have identified a number of miRNAs that are differentially expressed in LPS and IFNγ treated RAW264.7 cells, as compared to untreated cells. Microarray and quantitative real-time PCR (qRT-PCR) results showed that miR-103 decreased while the STAT1 expression increased substantially in RAW264.7 derived M1 macrophage, and there was a significant negative correlation between miR-103 and STAT1.Overexpression of miR-103 suppressed M1 polarization by inhibiting STAT1/IRF1 signaling pathway and vice versa in vitro. STAT1 is a direct target of of miR-103.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to evaluate the gene expression of M1-polarized RAW264.7 cells compared with M0 RAW264.7 cells. Methods: RAW264.7 cells were polarized toward M1 using LPS and IFN-γ. M0 RAW264.7 cells were maintained in culture without LPS and IFN-γ. Total RNA of M1 and M0 RAW264.7 cells was extracted. RAW264.7 cells RNA profiles were generated by deep sequencing for two groups (M1 versus M0 RAW264.7 cells) with three samples each. Results: There were significant differences between M1 and M0 RAW264.7 cells. Conclusions: Polarization of RAW264.7 cells from M0 to M1 induces various changes at the transcription level.
