In order to elucidate the mechanisms underlying the biobehavioral factors responsible for cervical cancer from the perspective of lncRNAs. Tumor samples were obtained from patients with stage Ib-IIb squamous cervical cancer, which were divided into high- and low-risk groups according to biobehavioral risk factors. A lncRNA + mRNA microarray was performed, and the results were validated using qRT-PCR. Gene ontology (GO), pathway, and lncRNA-mRNA co-expression analysis were performed to predict the potential functions of the differentially expressed transcripts...

PURPOSE: Recently, long noncoding RNAs (lncRNAs) have caught more attention for their role in tumor progression. Colon cancer is one of these ordinary malignant tumors. This study aimed to identify how lnc RNA PVT1 affects the progression of colon cancer. METHODS: PVT1 expression of both colon cancer cell tissue and 60 paired cancer and peri-tumoral tissue samples was detected by real-time quantitative polymerase chain reaction (RT-qPCR). The associations between lnc RNA PVT1 expression level and clinicopathological characteristics and patients' disease-free survival rate were evaluated...

A growing body of evidence has shown bisphenol A (BPA), an estrogen-like industrial chemical, has adverse effects on the nervous system. In this study, we investigated the transcriptional behavior of long non-coding RNAs (lncRNAs) and mRNAs to provide the information to explore neurotoxic effects induced by BPA. By microarray expression profiling, we discovered 151 differentially expressed lncRNAs and 794 differentially expressed mRNAs in the BPA intervention group compared with the control group. Gene ontology analysis indicated the differentially expressed mRNAs were mainly involved in fundamental metabolic processes and physiological and pathological conditions, such as development, synaptic transmission, homeostasis, injury, and neuroinflammation responses...

Long non-coding RNAs (lncRNAs) have been reported to be of great importance in the formation and progression of a wide range of human carcinomas including prostate cancer (PCa). Among them, PCAT3 and PCAT9 have been identified as two prostate tissue-specific lncRNAs and are up-regulated in PCa. However, their roles in the biological characteristics of PCa have not been fully elucidated. In the present study, our data revealed that knockdown of PCAT3 and PCAT9 suppressed cellular proliferation, invasion, migration, angiogenesis and stemness in androgen-dependent LNCaP and 22Rv1 cells...

Malignant glioma is one of the most common types of primary brain tumours. Long non-coding RNAs (lncRNAs) have recently emerged as a new class of therapeutic targets for many cancers. In this study, we aimed to explore the functional involvement of small nucleolar RNA host gene 14 (SNHG14) and its potential regulatory mechanism in glioma progression. SNHG14 was found to be downregulated in human glioma tissues and cell lines. SNHG14 significantly inhibited cell viability, reduced cell invasion, and induced apoptosis in glioma cell lines...

Renal cell carcinoma (RCC) is the most common kidney malignancy with poor prognosis. Recently, long noncoding RNAs (lncRNAs) have been demonstrated as important regulators in multiple cancers including RCC. LOC653786 is a lncRNA, but its role in cancer remains unclear. In this study, we for the first time found that LOC653786 was upregulated in RCC tissues and cell lines, and this lncRNA promoted growth and cell cycle progression of RCC cells. Moreover, we showed that LOC653786 elevated the expression of forkhead box M1 (FOXM1) and its downstream target genes cyclin D1 and cyclin B1 in RCC cells...

Infantile hemangioma (IH) is the most common vascular tumour in infants. The pathogenesis of IH is complex and poorly understood. Therefore, achieving a deeper understanding of IH pathogenesis is of great importance. Here, we used the Ribo-Zero RNA-Seq and HiSeq methods to examine the global expression profiles of protein-coding transcripts and non-coding RNAs, including miRNAs and lncRNAs, in IH and matched normal skin controls. Bioinformatics assessments including gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) pathway analyses were performed...

Lung cancer is among the leading causes of cancer-associated mortality worldwide, with a low 5-year survival rate of 16.1%. However, the underlying molecular mechanisms behind lung cancer tumorigenesis remain largely unknown. Long non-coding RNAs (lncRNAs) have been demonstrated to serve a function in the tumorigenesis of multiple types of cancer. The objective of the present study was to identify the function of a newly identified lncRNA zinc finger E-box-binding homeobox 2 antisense RNA 1 (ZEB2-AS1) in human lung cancer...

Esophageal cancer is one of the most common types of malignant tumors located within the digestive system, with >50% of esophageal cancer cases worldwide occurring in China. Recent studies have demonstrated that long non-coding RNAs (lncRNAs) are frequently dysregulated in cancer; however, few lncRNAs have been characterized in esophageal squamous cell carcinoma (ESCC). In the present study, a novel lncRNA, SET-binding factor 2 (SBF2) antisense RNA1 (SBF2-AS1) was exhibited in ESCC. Expression levels of SBF2-AS1 in ESCC and adjacent non-cancerous tissues were detected using the reverse transcription-quantitative polymerase chain reaction...

The endothelial lining can be viewed as the first line of defense against risk factors of vascular disease. Endothelial dysfunction is regarded as an initial event for atherogenesis since defects in vascular integrity and homeostasis are responsible for lipid infiltration and recruitment of monocytes into the vessel wall. Monocytes-turned-macrophages, which possess astounding inflammatory plasticity, perpetuate chronic inflammation and growth of atherosclerotic plaques and, are therefore central for the pathogenesis of atherosclerosis...

Non-coding RNAs, once considered "genomic junk", are now known to play central roles in the dynamic control of transcriptional and post-transcriptional gene expression. Long non-coding RNAs (lncRNAs) are an expansive class of transcripts broadly described as greater than 200 nucleotides in length. While most lncRNAs are species-specific, their lack of conservation does not imbue a lack of function. LncRNAs have been found to regulate numerous diverse biological functions, including those central to macrophage differentiation and activation...
