Core Tip
Core tip: We describe new findings on the overexpression of lncRNACNN3-206 in intestinal lesions of Crohn’s disease (CD) patients by high throughput sequencing. Moreover, forced overexpression of lncRNACNN3-206 led to apoptosis of Caco-2 and HT-29 cells. Since the 3' end of lncRNACNN3-206 and the 3’ UTR of Caspase10 contain high-affinity binding sites of miR-212, whereby lncRNACNN3-206 regulates Caspase10 expression and cell apoptosis/invasion through miR-212 sponging. This mechanism was supported by results from cell lines and the CD mouse model. In conclusion, lncRNACNN3-206 may play a key role in CD pathogenesis, and could be a therapeutic target for CD treatment.
