Cancer&Entry Information
| Cancer Name | papillary thyroid cancer |
| ICD-0-3 | NA |
| Methods | qPCR, luciferase reporter assay, other |
| Sample | PTC tissues and cells lines (BCPAP, TPC, K1, and IHH4) |
| Expression Pattern | up-regulated |
| Function Description | Our results indicated that hsa_circ_0004458 was upregulated in PTC tissues and cells, while silencing of hsa_circ_0004458 suppressed PTC cell proliferation and promoted PTC cell cycle arrest and apoptosis in vitro. Tumor formation assay in nude mice showed that knockdown of hsa_circ_0004458 by siRNAs inhibited the growth of PTC tumor in vivo. In addition, we found that miR-885-5p was a direct target of hsa_circ_0004458, and silencing of hsa_circ_0004458 inhibited PTC cell proliferation by miR-885-5p. We also demonstrated that RAC1 was a direct target of miR-885-5p and silencing of RAC1 suppressed PTC cell proliferation. |
