JianPiTongLuo (JPTL) Recipe regulates anti-apoptosis and cell proliferation in colorectal cancer through the PI3K/AKT signaling pathway.

BACKGROUND

JianPiTongLuo Recipe (JPTL Recipe) is a traditional Chinese medicine formula commonly used in the clinical treatment of colorectal cancer. Clinical studies have found that it can significantly improve the prognosis of patients with colorectal cancer. However, its mechanisms of action are not well understood, which has limited its further clinical application.

METHODS

We investigated the potential mechanisms of action of the JianPiTongLuo (JPTL) Recipe on colorectal cancer (CRC) using a multi-step approach. Initially, network pharmacology and bioinformatics analyses were conducted using databases such as TCMSP, HERB, BATMAN-TCM, and STRING to identify active components of JPTL Recipe and predict their therapeutic targets. Interaction networks and functional enrichment analyses were constructed to hypothesize relevant biological processes and pathways. In vitro studies involved treating human CRC cell lines HCT116, LoVo and SW480 with varying concentrations of JPTL Recipe extract, measuring cell viability with the CCK-8 assay, assessing apoptosis via flow cytometry, and analyzing signaling pathways through Western blotting. To corroborate these findings, in vivo experiments were performed on BALB/c nude mice implanted with HCT116 cells, divided into control, JPTL Recipe-treated, 5-fluorouracil (5-FU)-treated, and JPTL Recipe combined with 5-FU groups, with tumor growth and histological changes monitored. Mechanistic studies focused on the PI3K/AKT signaling pathway, examining the phosphorylation status of key pathway proteins using immunofluorescence and Western blot analyses to elucidate JPTL Recipe 's interaction with pathway activity.

RESULTS

We demonstrated that JPTL Recipe effectively inhibits colorectal cancer cell proliferation, anti-apoptotic ability, and exerts synergistic therapeutic effects with fluorouracil. Further analysis revealed that JPTL Recipe affects the activity of colorectal cancer cells by inhibiting the phosphorylation of the PI3K/AKT signaling pathway.

CONCLUSION

In summary, we have discovered and confirmed that the traditional Chinese medicine compound JPTL Recipe can serve as a novel adjuvant therapy for colorectal cancer, offering a new treatment approach for the integration of traditional Chinese and Western medicine in the treatment of colorectal cancer.
