Natural compounds such as resveratrol and curcumin exhibit anticancer properties, but their combined mechanisms are not fully understood. This study investigated the synergistic effects of resveratrol and curcumin in MCF-7 breast cancer cells. Methods: Optimal drug concentrations were determined by CCK-8 assay, followed by flow cytometry to assess apoptosis in the four treatment groups (control, curcumin, resveratrol, and combination). Transcriptome sequencing and Western blotting were performed to identify molecular mechanisms. In parallel, a network pharmacology approach was applied by integrating TNBC-related DEGs from GSE38959 with predicted drug targets, followed by KEGG and GO enrichment analysis. Results: The combination of 200 μM resveratrol and 20 μM curcumin significantly inhibited cell growth (73.60±6.91% inhibition, P<0.001 vs. control) and increased apoptosis (52.80% apoptotic cells, P<0.001 vs. single agents). RNA-seq and enrichment analysis revealed activation of the TNF signaling pathway and modulation of the NF-κB signaling pathway in the combination treatment group. Network pharmacology further confirmed the convergence of curcumin and resveratrol targets on the TNF/NF-κB axis, which supported the transcriptomic findings. Western blot validation showed down-regulation of NF-κB, TNF-α, and c-Myc, along with up-regulation of Cleaved caspase-3(P<0.05 for all), reinforcing the observed effects from RNA-seq and network pharmacology analysis. Conclusion: Combined resveratrol and curcumin treatment synergistically induces apoptosis in MCF-7 cells via the TNF-α/NF-κB/c-Myc axis, supporting their potential as a complementary therapy for breast cancer.
