Abstract

Fangchinoline (FAN), an alkaloid extracted from Stephania tetrandra, has a variety of biological and pharmacological activities, but evidence of its effects on colon adenocarcinoma (COAD) is limited. Therefore, the present study aimed to elucidate the molecular mechanisms by which FAN affects COAD. The cytotoxicity, viability and proliferation of DLD‑1 and LoVo cells were assessed in the presence of FAN using MTT and colony formation assays. The effects of FAN on apoptosis and the cell cycle in COAD cells were analysed by flow cytometry, and the migration and invasion of these cells were assessed by wound healing and Transwell experiments. Furthermore, a network pharmacological analysis was conducted to investigate the target of FAN and the results were confirmed by western blotting. In addition, a xenograft model was established in nude mice, and ultrasound imaging was used to assess the preclinical therapeutic effects of FAN in vivo. To the best of our knowledge, the results of this study provided the first evidence that FAN inhibited cellular proliferation, stemness, migration, invasion, angiogenesis and epithelial‑mesenchymal transition (EMT), and induced apoptosis and G1‑phase cell cycle arrest. Network pharmacological analysis further confirmed that FAN prevented EMT through the epidermal growth factor receptor (EGFR)‑phosphoinositide 3‑kinase (PI3K)/AKT signalling pathway. Finally, FAN significantly repressed tumour growth and promoted apoptosis in xenografts. Thus, targeting EGFR with FAN may offer a novel therapeutic approach for COAD.
