RNA-seq analysis reveals that oleic acid exerts anti-inflammatory effects via modulating cell cycle in Raw264.7 cells
Background: Lipopolysaccharide (LPS), a structural and protective compound primarily found in ordinary benign bacteria, could induce pro-inflammatory effect in a macrophage cell line Raw264.7 cells. Additionally, we previously showed that oleic acid (OA) possessed apoptotic effect in mouseoriginated Raw264.7 cells as well.
Methods: Cellular and molecular methods including flowcytometry and Western blot as well as bioinformatic methods including RNAseq and analysis.
Results: We demonstrated that OA could alleviate LPS-activated inflammatory effects, including apoptosis and secretion of cytokines via the modulation of cell cycle process. Further analysis revealed that OA reduced the LPS-elevated expression of p21, but not p16.
Conclusion: Our investigation has provided detailed information on LPS stimulation and OA remission in Raw264.7 cells, and laid solid foundation for the potential pharmaceutical application of OA as an antiinflammatory agent.
