Abstract

In this study, we observed that brown seaweed fucoidan inhibited human breast cancer progression by upregulating microRNA (miR)-29c and downregulating miR-17-5p, thereby suppressing their target genes, a disintegrin and metalloproteinase 12 (ADAM12) and phosphatase and tensin homolog (PTEN), respectively. Moreover, fucoidan reduced the luciferase activity of 3'-untranslated region reporter; treatment of cells with the miR-29c mimic or miR-17-5p inhibitor also produced similar results. These effects of fucoidan inhibited the epithelial-mesenchymal transition in breast cancer cells, as evidenced by an increase in E-cadherin and a drop in N-cadherin, and inhibited breast cancer cell survival, as evidenced by the activation of the phosphoinositide 3-kinase/Akt pathway. Taken together, these findings demonstrate that fucoidan inhibits breast cancer progression by regulating the miR-29c/ADAM12 and miR-17-5p/PTEN axes. Fucoidan is a potential chemopreventive/chemotherapeutic agent for breast cancer.

Keywords: Fucoidan, miR-29c, ADAM12, miR-17-5p, PTEN, breast cancer cells.
