Schematic diagram of the FOXM1/β-Catenin complex in human osteosarcoma cells. Elevated DNA methylation in the upstream region of miR-370 results in its down-regulation, which leads to up-regulation of FOXM1 gene. FOXM1 directly binds β-Catenin to form a complex and helps β-Catenin to translocate from the cytoplasm to the nucleus, where the FOXM1-β-Catenin complex interacts with the T-cell factor/lymphoid enhancer factor (TCF/LEF) transcription factors, up-regulating the expression of downstream target genes of the Wnt/β-Catenin pathway such as c-Myc and Cyclin D1.
