Nevertheless, the precise mechanisms implicated have remained ambiguous. In present study, the model of HCC was set up by the 2-acetylaminofluorene (2-AAF)/partial hepatectomy (PH) in rats. To confirm the differentially expressed genes (DEGs) identified in the microarray analysis, real-time quantitative reverse transcription PCR (qRT-PCR) was conducted. In the meantime, the liquid chromatography-quadrupole time of flight mass spectrometry (LC-QTOF-MS/MS) was employed to characterize the component profile of DWYG. Consequently, the DWYG treatment exhibited the ability to reverse 51 variation genes induced by 2-AAF/PH. Additionally, there was an overlap of 54 variation genes between the normal and model groups. Upon conducting RT-qPCR analysis, it was observed that the expression levels of all genes were increased by 2-AAF/PH and subsequently reversed after DWYG treatment. Notably, the fold change of expression levels for all genes was below 0.5, with 3 genes falling below 0.25. Moreover, an investigation was conducted to determine the signaling pathway that was activated/inhibited in the HCC group and subsequently reversed in the DWYG group. Moreover, the component profile of DWYG encompassed a comprehensive compilation of 206 compounds that were identified or characterized. The findings of this study elucidated the potential alleviative mechanisms of DWYG in the context of HCC, thereby holding significant implications for its future clinical utilization and widespread adoption.</p></div>","PeriodicalId":17449,"journal":{"name":"Journal of Traditional and Complementary Medicine","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2225411023001360/pdfft?md5=bfa76b9673e97a298fbe5a8c4cb54ab9&pid=1-s2.0-S2225411023001360-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139193418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
