Cancer&Entry Information
Cancer Name | non small cell lung cancer |
ICD-0-3 | C34 |
Methods | qPCR, Western blot, Luciferase reporter assay, in vitro knockdown |
Sample | non small cell lung cancer tissues, cell lines (A549, H358, H460, H1299,and PC9) |
Expression Pattern | up-regulated |
Function Description | XIST is aberrantly upregulated in NSCLC tissues and cell lines. XIST depletion inhibited cell proliferation and TGF-?1-induced EMT in A549 and H1299 cells. Spearman's correlation analysis showed an inverse correlation between miR-137 and XIST in NSCLC tissues, and miR-137 levels were found to be aberrantly reduced in A549 and H1299 cells. Furthermore, XIST could act as an endogenous sponge by directly binding to miR-137, negatively regulating its expression. miR-137 overexpression inhibited proliferation and TGF-?1-induced EMT in A549 and H1299 cells, whereas XIST could reverse the inhibitory effect of miR-137 on proliferation and TGF-?1-induced EMT. In addition, Notch-1 was identified as a direct target gene of miR-137, with the XIST-miR-137 axis regulating activation of the Notch-1 pathway. |
