Non-targeted metabolomics of spleen and liver metabolism in mice treated with Pruni Semen processed with different methods
Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)was employed to investigate the impacts of Pruni Semen processed with different methods(raw and fried)on the liver and spleen metabolism in mice.A total of 24 male mice were randomly assigned to three groups:raw Pruni Semen group,fried Pruni Semen group,and control(deionized water)group.Mice in the three groups were orally administrated with 0.01 g·mL-1 Pruni Semen decoction or deionized water for one week.After that,the liver and spleen tissues were collected,and liquid chromatography-mass spectrometry(LC-MS)-based metabolomic analysis was carried out to investigate the impact of Pruni Semen on the liver and spleen metabolism in mice.Compared with thte control group,the raw Pruni Semen group showed up-regulation of 11 metabolites and down-regulation of 57 metabolites in the spleen(P＜0.05),as well as up-regulation of 15 metabolites and down-regulation of 58 metabolites in the liver(P＜0.05).The fried Pruni Semen group showed up-regulation of 31 metabolites and down-regulation of 10 metabolites in the spleen(P＜0.05),along with up-regulation of 26 metabolites and down-regulation of 61 metabolites in the liver(P＜0.05).The differential metabolites identified in the raw Pruni Semen group were primarily associated with alanine,aspartate,and glutamate metabolism,purine metabolism,amino sugar and nucleotide sugar metabolism,and D-glutamine and D-glutamate metabolism.The differential metabolites identified in the fried Pruni Semen group predominantly involved riboflavin metabolism,amino sugar and nucleotide sugar metabolism,purine metabolism,alanine,aspartate,and glutamate metabolism,D-glutamine and D-glutamate metabolism,and glutathione metabolism.The findings suggest that both raw and fried Pruni Semen have the potential to modulate the metabolism of the liver and spleen in mice by influencing the glutamine and glutamate metabolism.
