Abstract

Background

Colorectal cancer (CRC) ranks among the most lethal malignancies globally, particularly following metastasis which results in poor prognosis. In recent years, CRC incidence in China has persistently increased. Total flavonoids (TFA) from , 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 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. 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.
