Intervention effect of Qi-Yu-San-Long Decoction on Lewis lung carcinoma in C57BL/6 mice: Insights from UPLC-QTOF/MS-based metabolic profiling
J Chromatogr B Analyt Technol Biomed Life Sci 2018 Dec 1;1102-1103:23-33.PMID:30366209DOI:10.1016/j.jchromb.2018.10.013.
Qi-Yu-San-Long Decoction (QYSLD) has been used to treat lung carcinoma for over twenty years in clinical practices, and its curative effect is considered credible. However, the therapeutic mechanism of this effect has not been thoroughly elucidated to date. In this study, a MTT dye reduction assay and DAPI staining were first used to evaluate the cell viability and apoptosis of A549 cells with and without QYSLD-treatment, respectively. The weight/volume of Lewis lung carcinoma (LLC) sarcoma was used to assess the therapeutic effect of QYSLD on LLC mice. Second, an UPLC-QTOF/MS-based untargeted metabolomics method was employed to identify and relatively quantify functional metabolites that were responsible for the intervention effect of QYSLD on LLC. As a result, the MTT dye reduction assay and DAPI staining demonstrated that QYSLD could inhibit the proliferation and induce the apoptosis of A549 cells. The weight/volume test of LLC sarcoma showed that QYSLD could restrain the development of LLC. Next, 21 potential biomarkers that could contribute to the curative mechanism of QYSLD on LLC were screened by the untargeted metabolomics method. The down-regulated metabolites induced by QYSLD included PC(16:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)), PC(20:2(11Z,14Z\)/16:0), PC(22:4(7Z,10Z,13Z,16Z)/14:0), PC(22:5(7Z,10Z,13Z,16Z,19Z)/14:0), arachidonic acid, gamma-glutamylisoleucine, cholesterol sulfate, CL (8:0/10:0/11:0/a-13:0) and CDP-DG (16:0/18:1(11Z)). The up-regulated metabolites were LysoPC(16:0), LysoPC(18:0), LysoPE(18:2(9Z,12Z)/0:0), LysoPE(22:0/0:0), LysoPE(22:1(13Z)/0:0), LysoPE(22:2(13Z,16Z)/0:0), triglylcarnitine, 1‑arachidonoylglycerophosphoinositol, 1‑palmitoylglycerophosphoinositol, 2‑stearoylglycerophosphoinositol, sphingosine 1‑phosphate(d19:1-P) and SM(d18:0/16:1(9Z)). The metabolic pathway analysis revealed that the potential biomarkers were primarily involved in glycerophospholipid metabolism, sphingolipid metabolism, steroid hormone biosynthesis, fatty acid degradation and arachidonic acid metabolism. This study demonstrated that QYSLD has a good antitumor effect and that a UPLC-QTOF/MS-based untargeted metabolomics method is a promising means of elucidating the intervention mechanism of traditional Chinese medicine formulas.
Untargeted metabolomics profiles delineate metabolic alterations in mouse plasma during lung carcinoma development using UPLC-QTOF/MS in MSE mode
R Soc Open Sci 2018 Sep 19;5(9):181143.PMID:30839735DOI:10.1098/rsos.181143.
In this work, an untargeted metabolomic method based on ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS) in MSE (E represents collision energy) mode was exploited to determine the dynamic metabolic alterations in the plasma of male C57BL/6 mice during the onset and development of lung carcinoma. Plasma samples were collected from control and model mice (male C57BL/6 mice experimentally inoculated with the Lewis lung carcinoma cells) at 7 and 14 days post-inoculation (DPI). As a result, 15 dysregulated metabolites, including cholesterol sulphate, tiglylcarnitine, 1-palmitoylglycerophosphoinositol, 2-stearoylglycerophosphoinositol, stearoylcarnitine, PC(20:2(11Z,14Z\)/16:0), PC(22:4(7Z,10Z,13Z,16Z)/14:0), PC(22:5(7Z,10Z,13Z,16Z,19Z)/14:0), PC(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/16:0), 12,20-Dioxo-leukotriene B4, sphingosine 1-phosphate(d19:1-P), sphingomyelin(d18:0/16:1(9Z)), lysoPC(16:0), lysoPC(18:0) and lysoPC(20:4(5Z,8Z,11Z,14Z\)), were identified in the plasma of model mice with xenografts at both 7 and 14 DPI. All the altered metabolites associated with the onset and development of lung carcinoma were involved in the metabolism of glycerophospholipid, fatty acid, sphingolipid and arachidonic acid. The feasible utility of these endogenous biomarkers as potential diagnostic indicators was validated through receiver operating characteristic curve analysis. Collectively, these findings provide a systematic view of metabolic changes linked to the onset and development of lung carcinoma.
