OBJECTIVE: Long non-coding RNAs (lncRNAs) play an important role in various cellular biological processes. It is also involved in the occurrence and development of the tumor. BCAR4 is reported to be highly expressed in breast cancer and promotes cell proliferation. However, the biological effects of BCAR4 in non-small cell lung cancer (NSCLC) remains unclear. PATIENTS AND METHODS: qRT-PCR was performed for detecting BCAR4 expression in 76 pairs of NSCLC tissues and corresponding cancer-adjacent tissues and 6 NSCLC cell lines...

The long non-coding RNA, HOTTIP, has an important role in tumorigenesis. It is known that HOTTIP regulates HOX gene family; however, its regulatory mechanism in esophageal squamous cell carcinoma (ESCC) remains elusive. In this study, we investigated the role of HOTTIP in ESCC and observed that HOTTIP/HOXA13 was upregulated in ESCC and promoted cell proliferation and metastasis in vivo and in vitro. Interestingly, harboring a miR-30b-binding site, HOTTIP as a molecular sponge mainly regulated miR-30b level in the nucleus and modulated the repression of HOXA13 mediated by miR-30b in the cytoplasm, resulting in the positive HOTTIP/HOXA13 correlation...

Cholangiocarcinoma (CCA) is a deadly disease that poorly responds to chemotherapy and radiotherapy and whose incidence has increased worldwide. Furthermore, long noncoding RNAs (lncRNAs) play important roles in multiple biological processes, including tumorigenesis. Specifically, H19, the first discovered lncRNA, has been reported to be overexpressed in diverse human carcinomas, but the overall biological role and clinical significance of H19 in CCA remains unknown. In the present study, expression levels of H19 were investigated in CCA tissues and cell lines and were correlated with clinicopathological features...

Dysregulated long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) play key roles in the development of human cancers. The lncRNA growth arrest-specific 5 (GAS5) is reported to be a tumor suppressor in multiple cancers. However, the roles of GAS5 and its related miRNAs in osteosarcoma are poorly understood. This study explored the potential functions and mechanisms of GAS5 in the tumorigenesis of osteosarcoma. Here, the expression of GAS5, miR-221 and aplasia Ras homologue member I (ARHI) was determined in osteosarcoma tissues and cells by Real-time PCR (RT-qPCR)...

BACKGROUND: Recent evidence has shown that long noncoding RNAs (lncRNAs) are involved in the process of epithelial-mesenchymal transition (EMT). However, little research has focused on the expression profile of lncRNAs during EMT in human lens epithelial cells (LECs) and their functions have not yet been described. METHODS: Dysregulated lncRNAs and mRNAs in normal human lens epithelial B-3(HLE B-3) cells and during transforming growth factor β2(TGF-β2)-induced EMT were analyzed via lncRNA microarray...

Long non-coding RNA HOTAIR was regarded as an oncogene in multiple cancers. Previous studies have shown that HOTAIR is involved in the proliferation and tumorigenesis of renal carcinoma cells, while microRNA (miR)-217 functions as a tumor suppressor in renal cell carcinoma (Rcc). However, the underlying molecular mechanism of HOTAIR in Rcc, especially in association with miR-217, has not been studied. In this study, we first demonstrated that HOTAIR expression was upregulated, which was correlated with tumor progression, and miR-217 downregulated in Rcc tissues and cells...

A hypoxic microenvironment plays important roles in the progression of solid tumors, including oral squamous cell carcinoma (OSCC). Long noncoding RNAs (lncRNAs) have gained much attention in the past few years. However, it is not clear whether lncRNAs can regulate hypoxia adaptation of OSCC or which lncRNAs participate in this process. Using a lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC tissues compared with paired normal oral mucosa and in hypoxic OSCC cells compared with normoxic OSCC cells...

Colon cancer-associated transcript 1 (CCAT1), a long non-coding RNA (lncRNA), is upregulated and has a vital role in the pathogenesis of numerous cancers. Recently, its high expression was found in glioma tissues. miR-181b is downregulated in glioma and acts as a tumor suppressor. However, the exact mechanism of CCAT1 action in the regulation of glioma development remains unknown. CCAT1 and miR-181b expression was firstly examined in glioma tissue samples by real-time PCR. An RNA interference approach was used to downregulate CCAT1 expression and we analyzed the underlying mechanism of CCAT1 by using bioinformatics analysis, CCK-8 assay, Transwell assay, flow cytometry, luciferase assay, RNA immunoprecipitation, real-time PCR, Western blot, and xenograft models...

BACKGROUND: Accumulating evidence indicates dysregulated expression of the long non-coding RNA HOTAIR (lncRNA-HOTAIR) may play a significant role in tumor progression. LncRNA-HOTAIR promotes several processes in esophageal cancer (EC), including cell growth, differentiation, invasion and migration. However, the mechanisms by which lncRNA-HOTAIR promotes invasion and migration EC remain unclear. METHODS: LncRNA-HOTAIR and miR-148a expression were quantified in 40 paired human EC and tumor-adjacent tissues and EC cell lines by quantitative real-time PCR (qRT-PCR)...

microRNA-489 (miR-489) is a novel cancer-related miRNAs and functions as a tumor suppressor in human cancers. While, the clinical significance of miR-489 and its role in colorectal cancer (CRC) remain rarely known. Here, we found that the levels of miR-489 in CRC tissues were significantly lower than those in matched tumor-adjacent tissues. Furthermore, decreased levels of miR-489 also observed in CRC cell lines compared to HIEC cells. Clinicopathological analysis revealed that miR-489 underexpression was positively correlated with advanced pT stage, pN stage and AJCC stage...

The plasmacytoma variant translocation 1 gene (PVT1) is an oncogenic lncRNA with regulative effect on chemosensitivity in cervical cancer. However, the underlying mechanisms were not fully understood. In this study, HPV16 positive CaSki and SiHa cells were used as in-vitro cell model. Knockdown of HPV16 E7 significantly inhibited PVT1 and restored miR-195 expression. PVT1 directly interacts with EZH2 and the complex anchors in the promoter region of miR-195. PVT1 overexpression resulted in increased H3K27me3 levels in the miR-195 promoter region, while PVT1 knockdown decreased H3K27me3 levels in the promoter region...

Increasing evidence has demonstrated that aberrant expressions of long non-coding RNAs (lncRNAs) are involved in various malignancies, including hepatocellular carcinoma (HCC). This study aimed to investigate the role of lncRNA colon cancer-associated transcript 2 (CCAT2) in the progression of HCC. Quantitative real-time polymerase chain reaction analysis confirmed that CCAT2 was upregulated in HCC cell lines and cancerous tissues compared with normal liver cell line and adjacent normal tissue samples.
