BACKGROUND: Prostate cancer (PCa) is the most prevalent malignancy in men and often correlates with distant metastasis in its advanced stages. The study aimed to investigate the effects of Ugonin J, a natural compound isolated from Helminthostachys zeylanica, on PCa metastasis.
METHODS: The effects of Ugonin J on cell motility were assessed using migration and invasion assays. Reverse Transcription Quantitative PCR (RT-qPCR) and Western blotting were used to evaluate the impact of Ugonin J on mRNA and protein expression. RNA sequencing (RNA-seq) analysis was performed to investigate candidate mechanisms. Differential gene expression analysis in PCa patients was conducted using multiple databases.
RESULTS: Here, we reveal that Ugonin J blocks migration and invasion in PCa cells without affecting cell viability. RNA-seq analysis suggests that epithelial-mesenchymal transition (EMT) is potentially involved in Ugonin J's anti-motility effects. Ugonin J also suppresses the expression of mesenchymal markers N-cadherin, β-catenin, Snail, and Slug while upregulating the expression of the epithelial marker E-cadherin. Furthermore, among 13 A disintegrin and metalloproteinase (ADAM) proteins, A disintegrin and metalloproteinase domain-containing protein 9 (ADAM9) is the most downregulated following Ugonin J treatment, according to our RNA-seq data. Importantly, clinical data revealed that ADAM9 expression are higher in PCa patients than in healthy controls and are associated with distant metastasis. Transfection with ADAM9 cDNA reverses Ugonin J-regulated downregulation of EMT, migration, and invasion in PCa cells. Ugonin J inhibits ADAM9-dependent motility by downregulating the phosphoinositide 3-kinase (PI3K), protein kinase B (Akt) and nuclear factor-κB (NF-κB) pathways.
CONCLUSIONS: Our evidence suggests that Ugonin J is a novel therapeutic candidate for further development as a treatment for metastatic PCa.
