Evodiamine inhibits growth and induces apoptosis in a renal carcinoma cell line. - GreenMedInfo Summary

Chinese medicines are an important source of secondary metabolites with excellent antitumour activity. Evodia rutaecarpa, from the family Rutaceae, exhibits antitumour activity. Evodiamine (EVO), which was isolated from the fruit of E. rutaecarpa, exhibits robust antitumour activity. However, the antitumour mechanism of EVO remains unclear. In this study, we assessed the growth-inhibiting effect of EVO on two renal carcinoma cell lines. We found that EVO could change the morphology and decrease the viability and proliferation of cells in a time- and concentration-dependent manner in vitro. In addition, transcriptome analysis indicated that EVO can modulate the transcriptome of Caki-1 cells. In total, 7,243 differentially expressed genes were found, among which 3,347 downregulated genes and 3,896 upregulated genes were mainly involved in cell migration, apoptosis, cell cycle, and DNA replication. Furthermore, we demonstrated that EVO can cause apoptosis, arrest cells in the G2/M phase, and regulate the expression of apoptosis- and cell cycle-related genes in Caki-1 cells. Our study reveals the anticancer effects of EVO using cellular and molecular data, and indicates the potential uses of this compound as a resource to characterize the antitumour mechanisms of E. rutaecarpa.
