Previously, we found that long intergenic noncoding RNA-p21 (lincRNA-p21) inhibits hepatic stellate cell (HSC) activation and liver fibrosis via p21.
However, the underlying mechanism of the antifibrotic role of lincRNA-p21 in liver fibrosis remains largely unknown.
Here, we found that lincRNA-p21 expression was significantly downregulated during liver fibrosis.
In LX-2 cells, the reduction of lincRNA-p21 induced by TGF-β1 was in a dose- and time-dependent manner.
lincRNA-p21 expression was reduced in liver tissues from patients with liver cirrhosis when compared with that of healthy controls.
Notably, lincRNA-p21 overexpression contributed to the suppression of HSC activation.
lincRNA-p21 suppressed HSC proliferation and induced a significant reduction in α-SMA and type I collagen.
All these effects induced by lincRNA-p21 were blocked down by the loss of PTEN, suggesting that lincRNA-p21 suppressed HSC activation via PTEN.
Further study demonstrated that microRNA-181b (miR-181b) was involved in the effects of lincRNA-p21 on HSC activation.
The effects of lincRNA-p21 on PTEN expression and HSC activation were inhibited by miR-181b mimics.
We demonstrated that lincRNA-p21 enhanced PTEN expression by competitively binding miR-181b.
In conclusion, our results disclose a novel lincRNA-p21-miR-181b-PTEN signaling cascade in liver fibrosis and suggest lincRNA-p21 as a promising molecular target for antifibrosis therapy.
