Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Western blot, RIP etc. |
| Sample | cell lines (BT549, MCF7, T47D, MDA-MB-231, MDA-MB-453, MDA-MB-468, MCF10A, and ZR-7530) |

| Function Description | Here we report that the lncRNA PVT1 promotes KLF5/beta-catenin signaling to drive TNBC tumorigenesis. PVT1 is upregulated in clinical TNBC tumors. Using genetic approaches targeting PVT1 in TNBC cells, we found that PVT1 depletion inhibited cell proliferation, colony formation, and orthotopic xenograft tumor growth. Mechanistically, PVT1 binds with KLF5 and increases its stability via BAP1, which upregulates beta-catenin signaling, resulting in enhanced TNBC tumorigenesis. PVT1, KLF5, and beta-catenin were also revealed to be co-expressed in clinical TNBC samples. Our findings uncover a new singaling pathway to mediate TNBC, and provide PVT1 as a new target for improving treatment of TNBC. |
