BACKGROUND: Breast cancer is the leading cause of cancer-related death in the
world, and it is of great value to reveal the molecular mechanisms of breast
cancer progression and develop new therapeutic targets. METHODS: Transwell assay
is used to analyze the migration and invasion of breast cancer cells. Real-time
PCR and western blotting assay are applied to detect the expression levels of
epithelial-mesenchymal transition markers and the key members of Wnt/?-catenin
and PI3K/AKT signaling pathways. RESULTS: Manganese-12 acetate (Mn12Ac)
significantly inhibited the migration and invasion of MCF7 and MDA-MB-231 breast
cancer cells. Western blotting assay further showed that Mn12Ac significantly
upregulated E-cadherin, and downregulated N-cadherin and vimentin. We further
found that Mn12Ac reduced the mRNA expressions of epithelial-mesenchymal
transition-associated transcription factors snail, slug, twist1, and ZEB1 using
real-time PCR assay. Importantly, we further found that Mn12Ac significantly
reduced the Wnt1 and ?-catenin protein expressions, and suppressed the
phosphorylation of PI3K and AKT in MCF7 and MDA-MB-231 breast cancer cells. Very
interestingly, we also showed that Mn12Ac decreased the mRNA and protein
expressions of programmed cell death ligand 1. CONCLUSION: Taken together, our
results suggested that Mn12Ac inhibited the migration, invasion, and
epithelial-mesenchymal transition by regulating Wnt/?-catenin and PI3K/AKT
signaling pathways in breast cancer.
