title: Dynamic analysis of phospholipid metabolism of mouse macrophages treated with common non-steroidal anti-inflammatory drugs.
abstract: Through studying the changes of the total phospholipid components in mouse macrophages under the inflammatory status and the drug intervention status, we found the targets of non-steroidal anti-inflammatory drugs on phospholipids, thus providing the basis for the targets of in vitro anti-inflammatory effects of non-steroidal anti-inflammatory drugs. After RAW264.7 cells were pretreated with common non-steroidal anti-inflammatory drugs (aspirin and ibuprofen) and, respectively, stimulated with KLA for various periods (0.5, 4, 12, 16, and 24 h), the phospholipids were extracted. The dynamic changes of phospholipids in cells under various stimulations were analyzed with UPLC-Q-TOF-MS technique. Through the statistical analysis of Simca-P, we explored the potential targets of non-steroidal anti-inflammatory drugs on phospholipids. Through the dynamic analysis of phospholipids, we found two biomarkers (PC(17:1/18:1), PA(18:0/18:4)) which might be in vitro intervention inflammatory response targets of non-steroidal anti-inflammatory drugs. The analysis results show that in anti-inflammatory effects, non-steroidal anti-inflammatory drugs can inhibit COX, induce the cellular fatty acid desaturation and the changes of phospholipid components, stimulate free fatty acids, activate calcium ion channels of endoplasmic reticulum, and promote cell endocytosis, thus controlling inflammation and activating cells. Non-steroidal anti-inflammatory drugs can promote endocytosis, alter cell inflammatory response, and activate the process cells, thus realizing the anti-inflammatory effects.
