Hepatocellular carcinoma (HCC) is the fifth most common cancer around the world, along with high mortality and metastasis rate. Our present study aimed to explore the role of LncRNA HOTAIR in the progression of HCC. Our data showed that HOTAIR was overexpressed in HCC tissues and cell lines (Huh7, Hep3B, HepG2, MHCC97H). Overexpressed HOTAIR promoted invasion and migration of HCC cells (Huh7) by enhancing epithelial-mesenchymal transition (EMT). Besides that, miR-23b-3p was predicted to be a target of HOTAIR and decreased expression of miR-23b-3p was observed in HCC tissues and cell lines...

High-throughput analyses have revealed that the vast majority of the transcriptome does not code for proteins. These non-translated transcripts, when larger than 200 nucleotides, are termed long non-coding RNAs (lncRNAs), and play fundamental roles in diverse cellular processes. LncRNAs are subject to dynamic chemical modification, adding another layer of complexity to our understanding of the potential roles that lncRNAs play in health and disease. Many lncRNAs regulate transcriptional programs by influencing the epigenetic state through direct interactions with chromatin-modifying proteins...

Background: Liver cancer stem cells (LCSCs) are the key factors for cancer metastasis, recurrent, and drug resistance. LCSCs are originated from either hepatocytes dedifferentiation or differentiation arresting of liver normal stem cells (LNSCs). Differentiation-inducing therapy is a novel strategy in solid tumors. Furthermore, Notch signaling pathway has been proved to play important role in the process of hepatocytes differentiation. In previous study, a malignant transformation cellular model of LNSCs has been built up, and in this study we are trying to illustrate whether inhibition of Notch can reverse this malignant tendency and drive these malignant cells back to differentiate into mature hepatocytes...

BACKGROUND: The HOX transcript antisense intergenic RNA (HOTAIR) is a well-known long noncoding RNA (lncRNA) that plays a critical role in biological processes in most cancers. However, the function of HOTAIR in bladder cancer remains largely unknown. In this study, we hypothesize that tag single nucleotide polymorphisms (tagSNPs) in HOTAIR are associated with bladder cancer (BCa) risk. METHODS: We performed a hospital-based case-control study of 1050 cases and 1407 controls to investigate the associations between tagSNPs and the risk of BCa in a Chinese population...

An inexpensive, simple and rapid sensor platform capable of detecting cancer-related long non-coding RNA (lncRNA) with high accuracy is of great interest in the field of molecular diagnostics. Herein, we report on the development of a new colorimetric and electrochemical assay platform for long non-coding HOX transcript antisense intergenic RNA (HOTAIR) detection. Isothermal reverse transcription-recombinase polymerase amplification (RT-RPA) was performed to amplify HOTAIR sequences from a RNA pool extracted from a designated number of ovarian cancer cells and a small cohort of plasma samples derived from patients with ovarian cancer...

Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 30% of the non-Hodgkin's lymphoma patients. The underlying molecular mechanism of its pathogenesis is not well defined and the survival rate of DLBCL patients is very low. Moreover, the annual incidence and mortality of DLBCL is still rising. Accordingly, identification and characterization of new molecular pathways of DLBCL will lead to the development of novel diagnostic markers and molecular therapeutic targets. Long non-coding RNAs (LncRNA) are non-coding RNAs with a length greater than 200 bp in eukaryotic cells, which can regulate the expression of their target genes at the transcriptional and post transcriptional levels...

The lncRNA HOTAIR has been implicated in several human cancers. Here, we evaluated the molecular alterations and upstream regulatory mechanisms of HOTAIR in glioma, the most common primary brain tumors, and its clinical relevance. HOTAIR gene expression, methylation, copy-number and prognostic value were investigated in human gliomas integrating data from online datasets and our cohorts. High levels of HOTAIR were associated with higher grades of glioma, particularly IDH wild-type cases. Mechanistically, HOTAIR was overexpressed in a gene dosage-independent manner, while DNA methylation levels of particular CpGs in HOTAIR locus were associated with HOTAIR expression levels in GBM clinical specimens and cell lines...

Melanoma is the most lethal cutaneous cancer with a highly aggressive and metastatic phenotype. While recent genetic and epigenetic studies have shed new insights into the mechanism of melanoma development, the involvement of regulatory non-coding RNAs remain unclear. Long non-coding RNAs (lncRNAs) are a group of endogenous non-protein-coding RNAs with the capacity to regulate gene expression at multiple levels. Recent evidences have shown that lncRNAs can regulate many cellular processes, such as cell proliferation, differentiation, migration and invasion...

Purpose: PI3K and STAT3 are frequently activated in cancer progression. However, little is known about the underlying mechanisms by which PI3K and STAT3 regulate head and neck squamous cell cancer (HNSCC) growth. The lncRNA HOX transcript antisense RNA ( HOTAIR ) was found to modulate the progression of HNSCC. In this study, we attempted to establish the correlation of PI3K/STAT3/HOTAIR signaling with the progression of HNSCC and its sensitivity toward platinum-based and targeted anti-EGFR combination therapy...

Bone regeneration is very important for the recovery of some diseases including osteoporosis and bone fracture trauma. It is a multiple-step- and multiple-gene-involved complex process, including the matrix secretion and calcium mineralization by osteoblasts differentiated from mesenchymal stem cells (MSCs) and the absorption of calcium and phosphorus by osteoclasts differentiated from hematopoietic stem cells. Long noncoding RNAs (lncRNAs) are a family of transcripts longer than 200 nt without or with very low protein-coding potential...
