| Sample | cell lines (MCF-10A, T47D, MCF7, BT474, SKBR3, ZR-75-30, ZR-75-1, MDA-MB-231, BT549, and HCC1937), fresh breast tumor and adjacent non-cancerous breast tissue |
| Expression Pattern | up-regulated |
| Function Description | LINC01638 is highly expressed in TNBC tissues and cells.Mechanistically, LINC01638 interacts with c-Myc to prevent SPOP-mediated c-Myc ubiquitination and degradation. C-Myc transcriptionally enhances MTDH (metadherin) expression and subsequently activates Twist1 expression to induce EMT. Analysis of the epithelial marker E-cadherin and mesenchymal markers Vimentin and EMT-associated transcription factor Twist1 revealed that LINC01638 knockdown increased E-cadherin and reduced Vimentin and Twist1 expression at the mRNA (Fig. 2g) and protein (Fig. 2h) levels in MDA-MB-231 and BT549 cells, whereas LINC01638 overexpression showed an inverse effect in T47D cells (Fig. 2g, h). |
