Cancer&Entry Information
| Cancer Name | osteosarcoma |
| ICD-0-3 | NA |
| Methods | qPCR, Western blot, Luciferase reporter assay, RNAi, RIP, other |
| Sample | osteosarcoma tissues and cell lines(U20S, Saos-2, HOS, TE85, and MG-63) |
| Expression Pattern | down-regulated |
| Function Description | Low Kcnq1 expression and high KCNQ1OT1 expression were shown in osteosarcoma tissues and cells. Kcnq1 was negatively mediated by KCNQ1OT1 via DNMT1. The overexpression of Kcnq1 or knockdown of KCNQ1OT1 inhibited the proliferation, migration, and invasion, and it promoted the chemosensitivity to CDDP and apoptosis of MG-63 cells and its CDDP-resistant cell lines. Moreover, the same trend was observed in the cells following methylation inhibitor treatment. Collectively, knockdown of KCNQ1OT1 can inhibit the osteosarcoma progression through the Kcnq1/DNMT1 axis. |
