lncRNA HANR promotes tumorigenesis and increase of chemoresistance

lncRNA

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third leading cause of cancer-related death. Critical roles for long non-coding RNAs (lncRNAs) have recently been demonstrated for a variety of cancers, including hepatocellular carcinoma. However, the effect and mechanism of lncRNAs in HCC tumorigenesis and chemoresistance have not been extensively characterized. In the current study, ...

Identification of key lncRNAs in colorectal cancer progression based on associated protein–protein interaction analysis

lncRNA

Colorectal cancer (CRC) was one of the most commonly diagnosed malignancies. The molecular mechanisms involved in the progression of CRC remain unclear. Accumulating evidences showed that long noncoding RNAs (lncRNAs) played key roles in tumorigenesis, cancer progression, and metastasis. Researchers at Fudan University aimed to explore the roles of lncRNAs in the progression of CRC. In this study, the researchers aimed to ...

Microarray expression profiling of long non-coding RNAs in epithelial ovarian cancer

lncRNA

Although numerous long non-coding RNAs (lncRNAs) have been identified to be important in human cancer, their potential regulatory roles in epithelial tumorigenesis and tumor progression in ovarian cancer remain unclear. Researchers from Nanjing Medical University set out to investigate lncRNAs that were differentially expressed (DE) in epithelial ovarian cancer and to explore their potential functions. The lncRNA profiles in five pairs ...

Microarray profiling identifies long noncoding RNAs functionally involved in neurogenesis

lncRNA

The denervated hippocampus provides a proper microenvironment for the survival and neuronal differentiation of neural progenitors. While thousands of lncRNAs were identified, only a few lncRNAs that regulate neurogenesis in the hippocampus are reported. Researchers from Nantong University aimed to perform microarray expression profiling to identify long noncoding RNAs (lncRNAs) that might participate in the hippocampal neurogenesis, and investigate the potential ...

The lncRNA AK144841 could contribute to molecular cascades leading to tumor development

lncRNA

Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer. Although some of the early events involved in this pathology have been identified, the subsequent steps leading to tumor development are poorly defined. Researchers from Universite Cote d Azur demonstrate here that the development of mouse tumors induced by the concomitant application of a carcinogen and a ...

Logic programming to infer complex RNA expression patterns from RNA-seq data

lncRNA

To meet the increasing demand in the field, numerous long noncoding RNA (lncRNA) databases are available. Given many lncRNAs are specifically expressed in certain cell types and/or time-dependent manners, most lncRNA databases fall short of providing such profiles. Researchers at the University of Louisville have developed a strategy using logic programming to handle the complex organization of organs, their tissues ...

A potential role of LncRNAs expression in cardiac cell proliferation

lncRNA

Long non-coding RNAs (LncRNAs) have been identified to play important roles in epigenetic processes that underpin organogenesis. However, the role of LncRNAs in the regulation of transition from fetal to adult life of human heart has not been evaluated. Researchers at Wenzhou Medical University used immunofiuorescent staining to determine the extent of cardiac cell proliferation. Human LncRNA microarrays were applied ...

lncRNAs LOC146880 and ENST00000439577 may promote the progression of NSCLC

lncRNA

To identify what long non-coding RNAs (lncRNAs) are involved in non-small cell lung cancer (NSCLC), researchers from the Shanghai Jiao Tong University School of Medicine analyzed microarray data on gene expression and methylation. Gene expression chip and HumanMethylation450BeadChip were used to interrogate genome-wide expression and methylation in tumor samples. Differential expression and methylation were analyzed through comparing tumors with adjacent ...

Three Circulating LncRNA Predict Early Progress of Esophageal Squamous Cell Carcinoma

Previous studies revealed that circulating (either from plasma or serum) long non-coding RNA may predict the occurrence or prognosis of multiple human malignant tumors. In this study, researchers from Nanjing Medical University mainly explored whether circulating lncRNAs can be utilized as biomarkers predicting the development of human esophageal squamous cell carcinoma (ESCC). LncRNA microarray was applied to screen the potential ...

Alzheimer’s Disease Model Displays Distinct Hippocampal Expression Profiles of Long Non-coding RNAs

lncRNA

Alzheimer’s disease (AD), the most prevalent form of dementia worldwide, is a complex neurodegenerative disease characterized by the progressive loss of memory and other cognitive functions. The pathogenesis of AD is not yet completely understood. Although long non-coding RNAs (lncRNAs) have recently been shown to play a role in AD pathogenesis, the specific influences of lncRNAs in AD remain largely ...
