Epithelial-mesenchymal transition (EMT) process is considered as a key event in the activation of hepatic stellate cells (HSCs). Hedgehog (Hh) pathway is known to be required for EMT process. Long non-coding RNAs (lncRNAs) have been reported to be involved in a wide range of biological processes. Plasmacytoma variant translocation 1 (PVT1), a novel lncRNA, is often up-regulated in various human cancers. However, the role of PVT1 in liver fibrosis remains undefined. In this study, PVT1 was…

Long noncoding RNA PVT1 promotes EMT via mediating microRNA-186 targeting of Twist1 in prostate cancer.
TLDR
It is reported that PVT1 promotes prostate cancer invasion and metastasis by modulating EMT and can promote EMT by up-regulation of Twist1, a transcription factor associated with EMT, and the PVT 1/miR-186/Twist1 regulatory axis may be a new therapeutic target for prostate cancer.
MicroRNA-30a Suppresses the Activation of Hepatic Stellate Cells by Inhibiting Epithelial-to-Mesenchymal Transition
TLDR
The results suggest that miR-30a inhibits EMT process, at least in part, via reduction of Snai1, leading to the suppression of HSC activation in liver fibrosis.

TLDR
PVT1 expression was markedly upregulated in GC tissues and cell lines, and high expression levels of PVT1 were obviously correlated with advanced tumor stage and lymph node metastasis, suggesting that PVT 1 acted as a key role in GC pathogenesis and may serve as a potential therapeutic target for GC.
Regulatory long non-coding RNAs of hepatic stellate cells in liver fibrosis (Review)
TLDR
The present review highlighted the current knowledge on the role of lncRNAs in activating or inhibiting LF, revealing lnc RNAs that are likely to be biomarkers or therapeutic targets for LF.
Long noncoding RNA PVT1-214 promotes proliferation and invasion of colorectal cancer by stabilizing Lin28 and interacting with miR-128
TLDR
The findings support a model in which the PVT1-214/Lin28/let-7 axis serves as a critical regulator of CRC pathogenesis, which may simulate a new direction for CRC therapeutic development.
H19/miR‐148a/USP4 axis facilitates liver fibrosis by enhancing TGF‐β signaling in both hepatic stellate cells and hepatocytes
TLDR
A novel H19/miR‐148a/USP4 axis which promoted liver fibrosis via TGF‐β pathway in both HSC and hepatocyte is revealed, indicating that H19 could become a promising target for the treatment of liver fibrogenesis.
A lncRNA Gpr137b-ps/miR-200a-3p/CXCL14 axis modulates hepatic stellate cell (HSC) activation.
TLDR
A lncRNA Gpr137b-ps/miR-200a-3p/CXCL14 axis that modulates HSC activation and might exert an effect on the pathogenesis of liver fibrosis is demonstrated.
Long non‐coding RNA PVT1: Emerging biomarker in digestive system cancer
TLDR
PVT1 promotes proliferation, survival, invasion, metastasis and drug resistance in digestive system cancer cells, and there was a great probability it could be a novel biomarker in screening tumours, prognosis biomarkers and future targeted therapy to improve the survival rate in cancer patients.
Upregulation of the long non-coding RNA PVT1 promotes esophageal squamous cell carcinoma progression by acting as a molecular sponge of miR-203 and LASP1
TLDR
It is shown that PVT1 expression is significantly up-regulated in ESCC tumor samples compared with their normal counterparts and the first evidence of dysregulated PVT 1/miR-203/LASP1 axis in ES CC is provided.

Inhibitory effects of long noncoding RNA MEG3 on hepatic stellate cells activation and liver fibrogenesis.
TLDR
In this study, MEG3 levels were remarkably decreased in CCl4-induced mouse liver fibrosis models and human fibrotic livers as demonstrated by real-time quantitative PCR and the expression of M EG3 was downregulated in human hepatic stellate cell lines LX-2 cells in response to transforming growth factor-β1 stimulation in dose and time-dependent manner.
Salvianolic acid B-induced microRNA-152 inhibits liver fibrosis by attenuating DNMT1-mediated Patched1 methylation
TLDR
It is demonstrated that the antifibrotic effects caused by Sal B were, at least in part, via inhibition of EMT and the Hh pathway, resulting in the inhibition of the EMT in liver fibrosis.
The lncRNA H19 promotes epithelial to mesenchymal transition by functioning as miRNA sponges in colorectal cancer
TLDR
It is implied that the lncRNA H19 modulated the expression of multiple genes involved in EMT by acting as a competing endogenous RNA, which may build up the missing link between the regulatory miRNA network and EMT progression.
Suppression of hepatic stellate cell activation by microRNA-29b.
TLDR
Results suggested that miR-29b is involved in the activation of HSCs and could be a candidate molecule for suppressing their activation and consequent liver fibrosis.
DNA methylation and MeCP2 regulation of PTCH1 expression during rats hepatic fibrosis.
TLDR
It was indicated that hypermethylation of PTCH1 is associated with the perpetuation of fibroblast activation and fibrosis in the liver and data suggest that DNA methylation and MeCP2 may provide molecular mechanisms for silencing ofPTCH1.
Long non-coding RNA APTR promotes the activation of hepatic stellate cells and the progression of liver fibrosis.
