Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Western blot, in vitro knockdown |
| Sample | breast cancer tissues, cell lines (MDA-MB-231 and MCF-7) |
| Expression Pattern | up-regulated |
| Function Description | MIAT was over-expressed in ER-positive breast cancer tissues and ER-positive breast cancer cell line MCF-7. Activating estrogen signaling by diethylstilbestrol (DES) led to a dose- and time-dependent up-regulation of MIAT in MCF-7 cells that was dependent on ER?, as evidenced by ER? silencing and pharmacological inhibition using ER antagonist ICI 182780. Silencing MIAT decreased DES-induced MCF-7 cell proliferation while overexpressing MIAT increased MCF-7 cell proliferation. Further mechanistic study identified that MIAT was critical for G1 to S phase cell cycle transition. |
