Jaceidin Suppresses Melanoma Metastasis by Modulating ERK, JNK Pathways and Extracellular Matrix Degradation Proteins.

Metastatic melanoma, marked by its poor prognosis and frequent recurrence, is a particularly aggressive skin cancer. Jaceidin, a compound derived from flavonoids abundant in common fruits and vegetables, has attracted interest for its potential anti-cancer properties. Nevertheless, the specific effects of jaceidin on melanoma cells remained unclear before this study. Here, we examined the impact of jaceidin on two metastatic melanoma cell lines, HMY-1 and A2058. Our results demonstrate that jaceidin exerts a significant anti-metastatic effect against both cell lines. This inhibitory action involved modulating the phosphorylation of extracellular signal-regulated kinase and c-Jun N-terminal kinase, as well as suppressing proteins associated with epithelial-mesenchymal transition. Furthermore, jaceidin reduced the expression of extracellular matrix degradation proteins MMP-2 and cathepsins A. These compelling findings suggest that jaceidin warrants further investigation as a potential therapeutic agent for melanoma.
