Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Western blot, Luciferase reporter etc. |
| Sample | breast cancer tissues,cell lines(HEK-293T, MCF10A, MCF7, T47D)) |
| Expression Pattern | up-regulated |
| Function Description | In this study, we found that HOTTIP was markedly up-regulated in BCSCs and had a positive correlation with breast cancer progression. Functional studies revealed that overexpression of HOTTIP markedly promoted cell clonogenicity, increased the expression of the stem cell markers, OCT4 and SOX2, and decreased the expression of the differentiation markers, CK14 and CK18, in breast cancer cells. Knockdown of HOTTIP inhibited the CSC-like properties of BCSCs. Consistently, depletion of HOTTIP suppressed tumour growth in a humanized model of breast cancer. Mechanistic studies demonstrated that HOTTIP directly binds to miR-148a-3p and inhibits the mediation of WNT1, which leads to inactivation of the Wnt/?-catenin signalling pathway. |
