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:Appropriate bone mass is maintained by the actions of the main cells in the bone, osteoclasts and osteoblasts. The Stat3 transcription factor is known to have an effect on maintaining bone mass, but it is not known whether its key actions are in osteoblasts, osteoclasts, or both. Preliminary data indicated that Stat3 plays a role in osteoclast differentiation, but the mechanisms of this role are not yet understood. We performed a microarray analysis to understand what key players in osteoclast differentiation are affected by Stat3 transcriptional activity
