Abstract
BACKGROUND

Curcumin originates from the natural herb turmeric, and its antitumor effects have been known about for a long time. However, the mechanism by which curcumin affects gastric cancer (GC) has not been elucidated.

AIM

To elucidate the potential mechanisms of curcumin in the treatment of GC.

METHODS

Network pharmacological approaches were used to perform network analysis of Curcumin. We first analyzed Lipinski’s Rule of Five for the use of Curcumin. Curcumin latent targets were predicted using the PharmMapper, SwissTargetPrediction and DrugBank network databases. GC disease targets were mined through the GeneCard, OMIM, DrugBank and TTD network databases. Then, GO enrichment, KEGG enrichment, protein-protein interaction (PPI), and overall survival analyses were performed. The results were further verified through molecular docking, differential expression analysis and cell experiments.

RESULTS

We identified a total of 48 curcumin-related genes with 31 overlapping GC-related targets. The intersection targets between curcumin and GC have been enriched in 81 GO biological processes and 22 significant pathways. Following PPI analysis, 6 hub targets were identified, namely, estrogen receptor 1 (ESR1), epidermal growth factor receptor (EGFR), cytochrome P450 family 3 subfamily A member 4 (CYP3A4), mitogen-activated protein kinase 14 (MAPK14), cytochrome P450 family 1 subfamily A member 2 (CYP1A2), and cytochrome p450 family 2 subfamily B member 6(CYP2B6). These factors are correlated with decreased survival rates among patients diagnosed with GC. Molecular docking analysis further substantiated the strong binding interactions between Curcumin and the hub target genes. The experimental findings demonstrated that curcumin not only effectively inhibits the growth of BGC-823 cells but also suppresses their proliferation. mRNA levels of hub targets CYP3A4, MAPK14, CYP1A2, and CYP2B6 in BGC-823 cells were significantly increased in each dose group.

CONCLUSION

Curcumin can play an anti-GC role through a variety of targets, pathways and biological processes.

Keywords: Curcumin; Gastric cancer; Network pharmacology; Molecular docking; Survival analysis

Core Tip: This study aimed to elucidate the therapeutic mechanisms of curcumin in gastric cancer (GC). Through network pharmacology, core targets correlating to poor survival in patients with GC were identified, including estrogen receptor 1(ESR1),epidermal growth factor receptor (EGFR), cytochrome P450 family 3 subfamily A member 4 (CYP3A4), mitogen-activated protein kinase 14 (MAPK14), cytochrome P450 family 1 subfamily A member 2 (CYP1A2), and cytochrome p450 family 2 subfamily B member 6 (CYP2B6). Molecular docking confirmed the favorable interactions of curcumin with pivotal target genes. In vitro experiments validated the regulatory effects of curcumin on GC cells through these targets. The therapeutic efficacy of curcumin involves multitarget, multipathway, and multibiological processes, offering new insights into its clinical application in GC treatment.
