    Abstract:
    BACKGROUND: P-coumaric acid (p-CA) is a kind of phenylpropionic acid derived from aromatic amino acids, which is widely distributed in many plants and human diets. It has strong pharmacological and inhibitory effects on a variety of tumors. However, the role of p-CA in osteosarcoma, a tumor with a poor prognosis, is still unknown. Therefore, we aimed to evaluate the effect of p-CA on osteosarcoma and explore its potential mechanism. OBJECTIVE: This study aimed to investigate whether p-CA has an inhibitory effect on the growth of osteosarcoma cells and explore its potential mechanism. METHODS: MTT assay and clonogenic assay were used to detect the effect of p-CA on the proliferation of osteosarcoma cells. The effect of p-CA on apoptosis of osteosarcoma cells was detected by the Hoechst staining and flow cytometry. The effects of p-CA on the migration and invasion of osteosarcoma cells were detected by scratch healing assay and Transwell invasion assay. Western blot and PI3K/Akt pathway activator 740Y-P were used to detect the anti-tumor mechanism of p-CA on osteosarcoma cells. The effect of p-CA on osteosarcoma cells in vivo was verified by an orthotopic osteosarcoma tumor animal model in nude mice. RESULTS: MTT assay and clonogenic assay showed that p-CA inhibited the proliferation of osteosarcoma cells. Hoechst stain and flow cytometry showed that p-CA could induce apoptosis of osteosarcoma cells and lead to G2 phase arrest of osteosarcoma cells. Transwell assay and scratch healing assay found that p-CA could inhibit the migration and invasion of osteosarcoma cells. Western blot showed that p-CA could inhibit the activity of the PI3K/Akt signaling pathway in osteosarcoma cells, and 740Y-P could reverse its inhibitory effect. In vivo mouse models, p-CA has an antitumor effect on osteosarcoma cells in vivo, and at the same time, it has less toxic side effects on mice. CONCLUSION: This study demonstrated that p-CA could effectively inhibit the proliferation, migration and invasion of osteosarcoma cells and promote apoptosis. p-CA may play an anti-osteosarcoma role by inhibiting PI3K/Akt signaling pathway.
