BACKGROUND: Long non-coding RNAs (LncRNAs) have been demonstrated to play crucial role in tumor growth and metastasis for hepatocellular carcinoma (HCC). LncRNA FAL1 has been indicated to promote the progression of various cancers. However, the role of lncRNA FAL1 in HCC was poorly understood. METHODS: The expression levels of lncRNA FAL1 in HCC tissues and cells were determined by RT-qPCR. The roles of lncRNA FAL1 on HCC cells were investigated by MTT, colony formation, transwell, RT-qPCR, and Western blotting...

Astragaloside IV (AS-IV), the major active component of Astragalus membranaceus, has shown attractive anticancer effects in certain cancers. However, the roles and action mechanisms of AS-IV in hepatocellular carcinoma (HCC) are largely unclear. Long noncoding RNAs (lncRNAs) are recently revealed to have crucial roles in HCC initiation and progression, but whether lncRNAs participate in the anticancer roles of AS-IV are unknown. In this study, we demonstrated that AS-IV significantly downregulated lncRNA-ATB expression in a dose- and time-dependent manner in HCC cells...

Emerging evidence indicates that the long noncoding RNAs extensively participate in cancer progression. Nevertheless, the molecular pathogenesis of how these lncRNAs regulate tumorigenesis has not been fully elucidated especially in hepatocellular carcinoma (HCC). Here, we sought to define the role of a novel lncRNA named lncRNA-NEF in modulating epithelial to mesenchymal transition (EMT) in HCC. It was found that the lncRNA-NEF was transcriptionally activated by EMT suppressor FOXA2 and frequently downregulated in HCC cell lines as well as clinical specimens...

PURPOSE: HCC after insufficient radiofrequency ablation (RFA) could induce epithelial-mesenchymal transition (EMT) in residual tumors, resulting in rapid and aggressive recurrence. However the role of EMT related Long noncoding RNAs (lncRNAs) in residual tumor progression remains unclear. METHODS: Insufficient RFA was simulated in vitro by heating Huh7 cells in water bath at 47°C, named as Huh7-H. Cell invasion, migration assays and wound healing assay were conducted for functional analysis...

The delivery of tumor-suppressive noncoding RNAs (ncRNAs) including short ncRNAs (i.e., miRNAs) and long ncRNAs (lncRNAs) is put forward to treat tumors. In this work, novel rodlike supramolecular nanoassemblies (CNC @CB[8] @ PGEA) of degradable poly(aspartic acid) (PAsp) derivatives-grafted cellulose nanocrystals (CNCs) and hydroxyl-rich polycations (ethanolamine-functionalized poly(glycidyl methacrylate), PGEA) are proposed via typical cucurbit[8]uril (CB[8])-based host-guest interactions for delivery of different ncRNAs to treat hepatocellular carcinoma (HCC)...

Various studies revealed that numerous long noncoding RNAs (lncRNAs) have been found dysregulated in HCC and played important role in hepatocarcinogenesis, although the underlying mechanism still remains unclear. Herein, we reported AF119895, a new lncRNA which was identified from microarray and amplified in HCC. Functionally, AF119895 promoted migration and invasion of HCC cells both in vitro and in vivo. Furthermore, we identified that NXF3 was a downstream target of AF119895. NXF3 depletion could decrease HCC cells migration and invasion...

BACKGROUND: It has been widely accepted that hepatitis B virus X protein (HBx) plays an important role in hepatocellular carcinoma (HCC). This study aimed to explore the function of long non-coding RNAs (lncRNAs) in the epithelial-mesenchymal transition (EMT) induced by HBx. METHODS: The association between HBx and EMT markers was detected using immunohistochemistry in HCC tissues. The effect of HBx on HCC EMT was assessed through morphological analysis, transwell assay, metastatic in vivo study and detection of EMT markers...

Long noncoding RNAs (lncRNAs) are a new class of regulatory noncoding RNAs. Emerging evidences indicate that lncRNAs play a critical role in the development of hepatocellular carcinoma (HCC). Although several lncRNAs have been annotated, the association of most lncRNAs with HCC is unknown. In this study, we investigated lncRNA alterations in HCC by performing lncRNA microarray analysis. We identified a novel lncRNA called HCC-associated lncRNA (HCAL) that was highly expressed in HCC tissues. HCAL upregulation was clinically associated with poor differentiation, intravascular cancer embolus, and decreased survival of patients with HCC...

Numerous studies indicate that long noncoding RNAs (lncRNAs) are dysregulated in hepatocellular carcinoma (HCC) and might serve as potential diagnostic biomarkers and therapeutic targets of HCC. Therefore, it is interesting to globally identify the lncRNAs altered in HCC. In our study, we used microarray to profile the levels of lncRNAs and mRNAs in three pairs of HCC and their adjacent noncancerous samples. We found lncRNA-SVUGP2, which is a splice variant of the UGP2 gene, was down-regulated in HCC samples and correlates with a better prognosis in patients with HCC...

Increasing evidence highlights the important role of XIST, a long non-coding RNA (lncRNA), in the regulation of multiple cancers. However, the underlying mechanism of XIST in human hepatocellular carcinoma (HCC) still remains to be explored. Herein, intended to investigate the functional role of XIST in HCC initiation and progression. We first detected that XIST was significantly upregulated in HCC tissues and associated with tumor size and vascular invasion. Gain- and loss-of-function of XIST further presented that XIST promoted the progression of HCC cells, including proliferation, migration, and invasion...

This study aims to comprehensively analyze the diagnosis and prognosis of lncRNAs in hepatocellular carcinoma (HCC). From the Gene Expression Omnibus database, we screened out and analyzed the differently expressed lncRNAs and related mRNAs using bioinformatics methods. The expressions of lncRNAs were validated in tumor tissues, cell lines and the Cancer Genome Atlas database. At the same time, we also conducted an exploratory analysis on the diagnostic and prognostic ability of lncRNAs in HCC. In this study, we found that most of the targeted mRNAs promote the biological process of cell division, cellular component of nucleoplasm, molecular function of protein binding, which were significantly associated with 12 KEGG pathways...

Accumulating evidence has supported the significance of lncRNAs in tumorigenesis. Recently, some studies indicate the oncogenic role of lncRNA Nuclear Enriched Abundant Transcript 1 (NEAT1) in hepatocellular carcinoma (HCC). In our present study, we focused on the biological mechanisms through which NEAT1 can regulate HCC development. We found that NEAT1 was greatly upregulated in human HCC cell lines including Huh7, Hep3B, HepG2, Bel-7404 and SK-Hep1 cells compared to the normal human liver cell line LO2. In addition, we observed that miR-485 was significantly downregulated in HCC cells...

Ovarian cancer (OC) is one of the most fatal gynecological cancer in women worldwide. Long noncoding RNA (lncRNA) lncBRM was found to be associated with the progression and prognosis of hepatocellular carcinoma (HCC). However, the expression level, clinical significance and functions in OC tumorigenesis and progression remain unclear. Our present research demonstrated that lncBRM expression was significantly increased in OC tissues. Upregulation of lncBRM expression was correlated with histological grade, FIGO stages, lymph node metastasis and poor prognosis of patients with OC...

Hepatocellular carcinoma (HCC) has become one of the most common leading causes of cancer-related deaths worldwide. This study investigates the role of lncRNA, SPRY4-IT1 in the development of HCC. Quantitative real-time PCR (qRT-PCR) was performed and the results showed that SPRY4-IT1 expression was up-regulated in HCC tissues and high expression of SPRY4-IT1 was associated with poor 5-year overall survival in the HCC patient cohort. Clinicopathological analysis showed that the expression of SPRY4-IT1 was significantly correlated with TNM stage in HCC patients...
