On the other hand, miR-320 was reported to inhibit the Wnt/β-catenin pathway in PC3 and DU145 cells with concurrent reductions in the cell-derived xenograft tumor formation in NOD/SCID mice, as well as the CD44+ cell subpopulation, Oct4 and ABCG2 expression [130]. This evidence concerns the gene ABCG2 and neoplasm.
