Glioblastomas (GBM) are very difficult to treat and their aggressiveness is one of the main reasons for this as well as for the frequent recurrences. MicroRNAs posttranscriptionally regulate their target genes through interaction between their seed sequence and 3'UTR of the target mRNAs. We previously reported that miR-296-3p is regulated by neurofibromatosis 2 (NF2) and enhances the invasiveness of GBM cells via SOCS2/STAT3. In this study, we investigated whether miR-296-5p, which originates from the same precursor miRNA as miR-296-3p, can increase the invasiveness of GBM cells...

Tumor suppressor miRNAs such as miR-34a inhibit tumor growth by simultaneously regulating the expression of multiple important oncogenes across multiple oncogenic pathways and, therefore, provide a strong rationale for developing therapeutic miRNA mimics in combination with other therapeutic cancer agents to augment drug sensitivity. Here, we describe the experimental approach for evaluating miRNA and drug combinations using the "fixed ratio" method in cultured non-small cell lung cancer cells.

This study provides evidence that the common rs2910164 polymorphism in miR-146a strongly correlates with lung cancer risk in nonsmoking females in northeast China. The genotypes of miR-146a rs2910164 were determined in 1131 patients with lung cancer and 1003 healthy control subjects. Tissue samples were used to evaluate the association between miRNA expression and lung cancer risk as well as the correlation between rs2910164 genotypes and miR-146a expression. The secondary structures of the wild-type and variant miR-146a sequences were predicted, and luciferase-based target assays were used to test whether miR-146a bound to tumor necrosis factor receptor associated factor 6 (TRAF6) mRNA...

Genetic variants of miRNAs that target DNMTs and MBDs involved in DNA methylation were scanned with current databases, and 35 miRSNPs in 22 miRNA genes were identified. The aim of the study was to determine the association between these variants of miRNA genes and lung cancer (LC). DNA samples were isolated from blood samples and genotyped using a Sequenom MassARRAY System. An association between the rs188912830 gene variant of miR3202 that targets the MeCP2 protein and LC was indicated in both subtypes. The presence of the C-allele in patients with LC and its subtypes was significantly lower, and the absence of the C-allele was determined to increase the risk of LC by 7,429-times compared to the presence (p=0,010)...

Identification of miRNA-disease association is a fundamental challenge in human health clinic. However, the known miRNA-disease associations are rare and experimental verification methods are expensive and time-consuming. Therefore, there is a strong incentive to develop computational methods. In this paper, we calculate the similarity score for each miRNAs pair by integrating miRNA functional similarity and miRNA family information. We use the disease phenotype similarity data to construct the disease similarity network...

Lung cancer is one of the most common deadly diseases worldwide, most of which is non-small cell lung cancer (NSCLC). The epidermal growth factor receptor (EGFR) mutant NSCLCs frequently respond to the EGFR tyrosine kinase inhibitors (EGFR-TKIs) treatment, such as Gefitinib and Erlotinib, but the development of acquired resistance limits the utility. Multiple resistance mechanisms have been explored, e.g., the activation of alternative tyrosine kinase receptors (TKRs) sharing similar downstream pathways to EGFR...

Dysregulation of microRNAs (miRNAs) expression is prevalent in human malignancy development and progression. As previously reported, miR-509-5p has been identified as a tumor suppressor in various cancers, but its role and functional mechanism in NSCLC remains unknown. In the present study, we found that miR-509-5p was significantly downregulated in non-small lung cancer (NSCLC) tissues and cell lines using Quantitative real-time PCR (qRT-PCR). In addition, overexpression of miR-509-5p markedly inhibited the proliferation, migration, invasion and phosphorylation of Akt of NSCLC cells...

Although previous studies suggested that microRNA-506-3p (miR-506-3p) was frequently downregulated, and functioned as a tumor suppressor in several cancers, the biological role and intrinsic regulatory mechanisms of miR-506-3p in non-small cell lung cancer (NSCLC) remain elusive. The present study found miR-506-3p expression was downregulated in advanced NSCLC tissues and cell lines. The expression of miR-506-3p in NSCLC was inversely correlated with larger tumor size, advanced TNM stage and lymph node metastasis...

Lung cancer early detection by low-dose computed tomography (LDCT) can reduce the mortality. However, LDCT increases the number of indeterminate pulmonary nodules (PNs), whereas 95% of the PNs are ultimately false positives. Modalities for specifically distinguishing between malignant and benign PNs are urgently needed. We previously identified a panel of peripheral blood mononucleated cell (PBMC)-miRNA (miRs-19b-3p and -29b-3p) biomarkers for lung cancer. This study aimed to evaluate efficacy of integrating biomarkers and clinical and radiological characteristics of smokers for differentiating malignant from benign PNs...

microRNAs (miRNAs/miRs) are crucial regulators of gene expression at the post-translational level through promoting mRNA degradation or the repression of translation of target genes. miRs have been confirmed to serve a dominant role in tumor biology. miR-486-5p has been ascertained to be involved in non-small-cell lung cancer, breast cancer and hepatocellular carcinoma; however, the expression and function of miR-486-5p in esophageal squamous cell carcinoma (ESCC) has yet to be elucidated. The present study aimed to analyze the expression levels of miR-486-5p in ESCC tissues and paired normal adjacent tissues, and determine the effects of miR-486-5p on esophageal cancer cells using MTT, wound scratch and apoptosis assays...

Hyperactivation of the PI3K/AKT pathway is observed in most human cancer including lung carcinomas. Here we have investigated the role of miRNAs as downstream targets of activated PI3K/AKT signaling in Non Small Cell Lung Cancer (NSCLC). To this aim, miRNA profiling was performed in human lung epithelial cells (BEAS-2B) expressing active AKT1 (BEAS-AKT1-E17K), active PI3KCA (BEAS-PIK3CA-E545K) or with silenced PTEN (BEAS-shPTEN).Twenty-four differentially expressed miRNAs common to BEAS-AKT1-E17K, BEAS-PIK3CA-E545K and BEAS-shPTEN cells were identified through this analysis, with miR-196a being the most consistently up-regulated miRNA...

Platinum-based chemotherapy toxicity severely impedes successful treatment in lung cancer patients. MicroRNAs (miRs) have a significant impact on the occurrence and survival rate of lung cancer. The purpose of this study was to investigate the association between common miRNA variants and platinum-based chemotherapy toxicity in lung cancer patients. A total of 8 functional SNPs of miRNA were genotyped in 408 lung cancer patients by MALDI-TOF mass spectrometry. All the patients were histologically confirmed as lung cancer, and were treated with platinum-based chemotherapy for at least two cycles...

The coordination between cellular differentiation and the mesenchymal/stem transition is essential for both embryo development and neoplasia, suggesting a mechanistic link between these two major processes. In this work we show that miR-127, an embryo-expressing lung miRNA, was prominently induced in lung adenocarcinoma and correlated with poor prognosis. Elevated miR-127 level drove a pronounced shift from the epithelial to the mesenchymal phenotype in cancer cells, and this shift was associated with their acquisition of stem-like traits, increased resistance to the epidermal growth factor receptor inhibitor and tumor-propagating potential...

Lung cancer is the most common cause of cancer deaths all over the world, in which non-small cell lung cancer (NSCLC) accounts for ~85% of cases. It is well known that microRNAs (miRNAs) play a critical role in various cellular processes, mediating post-transcriptional silencing either by mRNA degradation through binding the 3' UTR of target mRNA or by translational inhibition of the protein. In the past decade, miRNAs have also been increasingly identified in biological fluids such as human serum or plasma known as circulating or cell-free miRNAs, and may function as non-invasive diagnostic markers for various cancer types including NSCLC...

MicroRNAs (miRNA) are mostly downregulated in cancer. However, the mechanism underlying this phenomenon and the precise consequence in tumorigenesis remain obscure. Here we show that ERK suppresses pre-miRNA export from the nucleus through phosphorylation of exportin-5 (XPO5) at T345/S416/S497. After phosphorylation by ERK, conformation of XPO5 is altered by prolyl isomerase Pin1, resulting in reduction of pre-miRNA loading. In liver cancer, the ERK-mediated XPO5 suppression reduces miR-122, increases microtubule dynamics, and results in tumor development and drug resistance...

Deregulation of the imprinted DLK1-DIO3 locus at chromosome 14q32.1-14q32.31 has been associated with developmental and respiratory disorders, including cancer. In lung cancer, deregulation of imprinting at DLK1-DIO3 was recently described in smokers. Deregulated expression of a microRNA (miRNA) cluster mapping to this locus was also associated with patient outcome, suggesting the importance of this locus to lung cancer disease phenotypes. The DLK1-DIO3 locus is complex, and encodes several protein-coding genes, in addition to long and short non-coding RNAs...

Accumulating evidence has highlighted the important roles of long non-coding RNAs (lncRNAs) acting as competing endogenous RNAs (ceRNAs) in tumor biology. However, the roles of cancer specific lncRNAs in lncRNA-related ceRNA network of lung adenocarcinoma (LUAD) are still unclear. In the present study, the 465 RNA sequencing profiles in LUAD patients were obtained from the cancer genome atlas (TCGA) database, which provides large sample RNA sequencing data free of charge, and 41 cancer specific lncRNAs, 25 miRNAs and 1053 mRNAs (fold change >2, p<0...
