Furthermore, we identified Notch1 and lymphoid enhancer-binding factor 1 (LEF1) as target genes of miR-34c in OS cells and demonstrated that Notch1 and LEF1 have a major role in the effects of miR-34c on OS cell chemosensitivity and metastasis.
In this study, to further evaluate the role of hypoxia and Notch1 on drug resistance of OS, we investigated the influence of inhibiting Notch1 pathway by Notch1 small interference RNA (siRNA) on human MG-63 OS cells in hypoxia.
Our data provide the first evidence that the downregulation of Notch-1 and reexpression of miRNAs by DATS may be an effective approach for the treatment of osteosarcoma.
Overexpression of NOTCH1 is associated with osteosarcoma, and overexpression of NOTCH3 or JAGGED1 in breast cancer cells favors the formation of osteolytic bone metastasis.
The NOTCH1 inhibitor Crenigacestat (TargetMol, T3633) repressed LIF-mediated activation of the stemness-related genes in osteosarcoma patient-derived primary tissues.
