As Slug is the critical downstream effector of TGF‐β signaling, we tried to explore the mechanisms underlying UCA1‐mediated regulation of Slug expression, and since plenty of evidence has confirmed the ceRNA activity of lncRNAs, we wondered whether lncRNA UCA1 could act as a ceRNA for Slug in glioma cells 5, 7, 12. Here, SNAI2 is linked to glioma.
