Tauro ursodeoxycholic acid (TUDCA) inhibits human fibrosarcoma HT-1080 cell invasion through MMPs inactivation and the modulation of the MAPKs signaling pathway
摘要
Metastasis is the process by which cancer cells are disseminated from their primary site to distant locations, causing complications in anti-cancer treatments and a high rate of mortality. Therefore, the discovery of novel drug candidates that can inhibit metastasis progression is crucial for improving anti-cancer therapeutic outcomes. Tauro ursodeoxycholic acid (TUDCA) is a bile acid with known cytoprotective and anti-apoptotic properties. In this study, we investigated the anti-metastatic activity of TUDCA in 12-O-tetradecanoylphorbol-13-acetate (PMA) stimulated human fibrosarcoma HT-1080 cells. TUDCA treatment decreased cell viability in a dose-dependent manner in HT-1080 cells. TUDCA displayed the antimetastatic effect by significantly inhibiting the cell invasion and migration in HT-1080 cells at 5, 10, and 20 µM (p < 0.05). Gelatin zymography revealed that TUDCA inhibited the MMP2 and MMP9 activities in HT-1080 cells in a concentration-dependent manner. Western blot analysis showed that TUDCA treatment inhibited the phosphorylation of MAPK pathway-related ERK, JNK, and p38, along with suppression of nuclear translocation of p-p65 and c-FOS, confirming that TUDCA could modulate MAPK and NF-κB pathways for anti-metastatic activity. Furthermore, gene reporter assay confirmed that TUDCA inhibited the transcriptional activity of NF-κB and AP1. These results suggest that TUDCA could exert a potent anti-metastatic activity in PMA-stimulated HT-1080 cells through modulation of MMPs, MAPKs signaling pathway, and NF-κB and AP1 transcription factors.
