1 Metformin induces degradation of cyclin D1 via AMPK/GSK3beta axis in ovarian cancer. Metformin cyclin D1 Homo sapiens
2 Here, we first describe that the anti-cancer effect of metformin is mediated by cyclin D1 deregulation via AMPK/GSK3beta axis in ovarian cancer cells. Metformin cyclin D1 Homo sapiens
3 Metformin induced the G1 cell cycle arrest, in parallel with a decrease in the protein expressions of cyclin D1 without affecting its transcriptional levels. Metformin cyclin D1 Homo sapiens
4 Using a proteasomal inhibitor, we could address that metformin-induced decrease in cyclin D1 through the ubiquitin/proteasome process. Metformin cyclin D1 Homo sapiens
5 Cyclin D1 degradation by metformin requires the activation of GSK3beta, as determined based on the treatment with GSK3beta inhibitors. Metformin cyclin D1 Homo sapiens
6 These findings suggested that the anticancer effects of metformin was induced due to cyclin D1 degradation via AMPK/GSK3beta signaling axis that involved the ubiquitin/proteasome pathway specifically in ovarian cancer cells. Metformin cyclin D1 Homo sapiens
