| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qRT-PCR, Western blot, Luciferase reporter assay, in vitro knockdown |
| Sample | breast cancer cell line (SKBR-3) |
| Expression Pattern | up-regulated |
| Function Description | A luciferase reporter assay confirmed the association of miR-18a with wild-type UCA1 but not with UCA1 mutated at the predicted miR-18a-binding site. The direct targeting of YAP1 by miR-18a was verified by the observation that miR-18a mimic suppressed luciferase expression from a construct containing the YAP1 3' untranslated region. Meanwhile,reciprocal repression of UCA1 and miR-18a were found to be Argonaute 2-dependent. Knockdown of YAP1 recapitulated the effect of UCA1 silencing by reducing the viability of trastuzumab-treated breast cancer cells, whereas inhibition of miR-18a abrogated UCA1 knockdown-induced improvement of trastuzumab sensitivity in breast cancer cells. |
