Methods: Our study aimed to identify potential anti-OSCC targets of PS and explore its mechanisms and effects on prognosis through network pharmacology, bioinformatics analysis, molecular docking, and in vitro cell assays. Results: Sixty-two potential targets of 11 active anti-OSCC ingredients of PS were identified, with Quercetin, the core ingredient of PS, exhibiting the most significant number of OSCC-related targets. GO analysis indicated that the primary biological processes involved in OSCC treatment by PS were the cellular response to nitrogen compound, response to xenobiotic stimulus, and cellular response to organonitrogen compound. KEGG analysis revealed that Pathways in cancer were the top highly enriched signaling pathway in the treatment of OSCC by PS. DisGeNET analysis is mainly about Lip and Oral Cavity Carcinoma. More importantly, 6 of the 62 targets were markedly related to prognosis. Molecular docking revealed high affinities between the key component and the prognosis-related target proteins. Treatment of OSCC cell line SCC-25 with Quercetin could inhibit malignant biological behaviors, such as cell proliferation, colony formation, invasion, and migration, as well as affect the targets related to prognosis and promote autophagy.

In recent years, CRC incidence in China has persistently increased. Total flavonoids (TFA) from Abelmoschus manihot, a natural compound, are recognized for their anti-inflammatory, analgesic, and antioxidant properties. However, despite extensive research into the therapeutic potential of TFA, coverage of its role in cancer treatment is notably lacking. To address this research void, our study aims to unveil the role and potential mechanisms of TFA in treating CRC. Methods: We conducted a series of experiments to assess the impact of TFA on CRC cells. Two specific CRC cell lines, DLD-1 and HCT116, were employed in cell proliferation, colony formation, flow cytometry, and cell migration assays. Additionally, to test the in vivo effects of TFA, we developed a nude mouse xenograft tumor model to assess TFA's impact on tumor growth and liver metastasis. Furthermore, we meticulously analyzed the gene expression differences between CRC cells pretreated with TGF-β and those treated with TFA using RNA-seq technology. We also examined the molecular mechanisms of TFA and assessed the expression of proteins related to the STAT3/EMT signaling pathway through Western blotting and siRNA technology. Results: Our research findings reveal for the first time the effect of TFA on CRC cells. Result shows that TFA could suppress cell proliferation, migration, and induce apoptosis. In vivo results showed that TFA inhibited tumor growth and liver metastasis. Molecular mechanism studies have shown that TFA exerts these effects by upregulating the expression of non-coding RNA AL137782, inhibiting the EMT/STAT3 signaling pathway. These results suggest that TFA is a potential candidate for mitigating CRC metastasis. Conclusion: However, further research is needed to comprehensively evaluate the efficacy and safety of TFA in animal models and clinical settings. These findings bring great hope for the development of innovative CRC treatment methods.","PeriodicalId":10845,"journal":{"name":"Current pharmaceutical design","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
