Project description:We report the miRNA profile of murine macrophages (cell line: RAW264.7) after supplementation with polyunsaturated fatty acids (PUFA) and stimulation with LTA. The fatty acids docosahexaenoic acid (DHA, C22:6n3) or arachidonic acid (AA, C20:4n6) were included in the culture medium in concentrations of 15 µmol/L using ethanol as a vehicle (0.2 % v/v final ethanol concentration). Cells were cultured in the enriched media totaling 72 h. Stimulation of cells was performed in the last 24 h of fatty acid supplementation by addition of LTA (0.5 µg/mL; from Staphylococcus aureus).

Project description:We report the transcriptome of murine macrophages (cell line: RAW264.7) after supplementation with polyunsaturated fatty acids (PUFA) and stimulation with LPS. The fatty acids docosahexaenoic acid (DHA, C22:6n3) or arachidonic acid (AA, C20:4n6) were included in the culture medium in concentrations of 15 µmol/L using ethanol as a vehicle (0.2 % v/v final ethanol concentration). Cells were cultured in the enriched media totaling 72 h. Stimulation of cells was performed in the last 24 h of fatty acid supplementation by addition of LPS (1 µg/mL; from E. coli serotype 0111:B4).
Project description:We report the miRNA profiles of macrophages (cell line: RAW264.7) and endothelial cells (cell line: TIME) after supplementation with polyunsaturated fatty acids (PUFA) and stimulation with LPS/pro-inflammatory cytokines. The fatty acids docosahexaenoic acid (DHA, C22:6n3) or arachidonic acid (AA, C20:4n6) were included in the culture medium in concentrations of 15 µmol/L using ethanol as a vehicle (0.2 % v/v final ethanol concentration). Cells were cultured in the enriched media totaling either 72 h (RAW264.7) or 144 h (TIME). Stimulation of cells was performed in the last 24 h of fatty acid supplementation by addition of either LPS (1 µg/mL; from E. coli serotype 0111:B4) for cell line RAW264.7 or the cytokines IL-1β, TNF-α, and IFN-γ each in a concentration of 5 ng/ml for cell line TIME.
Project description:This study aimed to investigate the mechanism of C2S-induced macrophagic inflammation and its’ effect on osteogenic differentiation of precursor cells. This study used the C2S (75-150 μg/ml) extract to induce macrophagic inflammation in RAW264.7 murine macrophages. RNA sequencing was preformed for analyzing mechanism of mitochondrial function and autophagy.
Project description:To identify novel LXR target genes, we conducted transcriptional profiling studies using RAW264.7 cells ectopically expressing LXRalpha Total RNA was isolated from RAW264.7 macrophages ectopically expressing LXRalpha as described in Venkateswaran et al. (2000); PNAS 97, 12097-12102. Cells were cultured with DMSO or GW3965 (1 μM) and LG268 (100 nM). Transcriptional profiling was performed at the UCLA microarray core facility using murine Affymetrix 430 2.0 microarrays.
