Cancer stem cells (CSCs) play a central role in the development of cancer. The canonical Wnt/β-catenin pathway is critical for maintaining stemness of CSCs. Phytochemicals from dietary compounds possess anti-CSCs properties and have been characterized as promising therapeutic agents for the prevention and treatment of many cancers. To date, the involvement and function of miR-19, a key oncogenic miRNA, in regulating Wnt/β-catenin pathway and lung CSCs has not been defined. Meanwhile, the effect of sulforaphane (SFN) on lung CSCs also remains to be elucidated...

Evidence is mounting that micro RNAs (miRNAs) play a critical role in tumor development. However, the role of miRNAs in lung cancer progression remains largely unknown. Herein, we found that miR-98 significantly impaired in patients with non-small cell lung cancers (NSCLC) and was a novel regulator of NSCLC progression. Patients with high miR-98 expression had a longer overall survival than with low miR-98 expression (p=0.0495). miR-98 expression level inversely correlated with TWIST mRNA level in 71 clinical tissue specimens of NSCLC (p<0...

Non-small cell lung cancer is one of the most common cancers and the leading cause of cancer death worldwide. Genetic variants in regulatory regions of some miRNAs might be involved in non-small cell lung cancer susceptibility and survival. rs12220909 (G/C) genetic polymorphism in miR-4293 has been shown to be associated with decreased risk of esophageal squamous cell carcinoma. However, the influence of rs12220909 genetic variation on non-small cell lung cancer susceptibility has not been reported. In order to evaluate the potential association between miR-4293 rs12220909 and non-small cell lung cancer risk in a Chinese population, we performed a case-control study among 998 non-small cell lung cancer cases and 1471 controls...

Epithelial-mesenchymal transition (EMT) of alveolar type II epithelial cells may play an important role in the pulmonary fibrosis induced by drugs such as bleomycin (BLM) and methotrexate (MTX). In this study, we examined the role of microRNAs (miRNAs) in drug-induced EMT using RLE/Abca3, a cell line having alveolar type II cell-like phenotype. Based on the screening using miRNA microarray analysis, it was found that the expression of some miRNAs, such as miR-34a, was increased by transforming growth factor (TGF)-β1 and BLM...

miR-495 serves as an oncogenic miRNA or a tumor suppressor in different types of cancer. However, its role in the drug resistance of small cell lung cancer (SCLC) remains unidentified. In this study, we investigated whether miR-495 regulates the chemoresistance of SCLC through the epithelial-mesenchymal transition (EMT) via Epithelial and endothelial tyrosine kinase (Etk/BMX) using two drug-resistant cell lines. Loss- and gain-of-function experiments showed miR-495 regulated cell proliferation, tumor growth and drug resistance...

The toxicity of TiO2 nanoparticles (NPs) is controversial, while it is widely accepted for Co3O4 NPs. We present a comparative study concerning the uptake of these NPs and their effect on cytoplasmic organelles and autophagy in a human lung carcinoma cell line (A549), including assays on the expression of autophagy-related microRNAs. The NP accumulation caused a fast dose- and time-dependent change of flow cytometry physical parameters particularly after TiO2 NP exposure. The intracellular levels of metals confirmed it, but the Co concentration was ten times higher than that of Ti...

MicroRNAs (miRNAs) that negatively regulate gene expression play a key role in the development and progression of cancer. Aberrant expression of hsa-miR-187 (miR-187) has been reported in various malignancies. However, the function of miR-187 in tumor progression remains controversial and its role in non-small cell lung cancer (NSCLC) is poorly understood. In the present study, the role of miR-187 in the progression of NSCLC was investigated. Our results revealed that miR-187 was frequently upregulated in NSCLC tissues and cells...

MicroRNA-221 (miRNA-221) plays an important role in occurrence and development of tumor. However, expression pattern and role of miRNA-221 in the non-small-cell lung carcinoma (NSCLC) remains poorly understood. In the current study, we explored the roles and the underlying mechanism of miR-221 in NSCLC by gain and loss of function analysis. We found that the expression of miRNA-221 is significantly higher in NSCLC tissues and NSCLC cells compared to normal tissues and cells, respectively (P<0.05). NSCLC cell lines SPCA1 and H1299 were transfected with miRNA-221 mimic or inhibitor, respectively, and then performed to analysis...

In this study, we aimed to identify potential microRNA (miRNA) regulators of angiotensin-converting enzyme 2 (ACE2) and to explore their roles in lipopolysaccharide (LPS)-induced acute lung injury (ALI). The expression of predicted miRNA regulators of ACE2 was examined in LPS-exposed pulmonary microvascular endothelial cells (PMVECs). Gain- and loss-of-function studies were performed to determine the functions of candidate miRNAs in LPS-induced PMVEC apoptosis and inflammatory response. The roles of the miRNAs in LPS-induced lung inflammation and permeability were investigated in a mouse model...

Although different preclinical models have demonstrated a favorable role for bone marrow derived mesenchymal stem cells (B-MSC) in preventing fibrosis, this protective effect is not observed with late administration of these cells, when fibrotic changes are consolidated. We sought to investigate whether the late administration of B-MSCs overexpressing microRNAs (miRNAs) let-7d (anti-fibrotic) or miR-154 (pro-fibrotic) could alter lung fibrosis in a murine bleomycin model. Using lentiviral vectors we transduced miRNAs (let-7d or miR-154) or a control sequence into human B-MSCs...

Asthma is highly prevalent, but current therapies cannot influence the chronic course of the disease. It is thus important to understand underlying early molecular events. In this study, we aimed to use microRNAs (miRNAs) - which are critical regulators of signaling cascades - to identify so far uncharacterized asthma pathogenesis pathways. Therefore, deregulation of miRNAs was assessed in whole lungs from mice with ovalbumin (OVA)-induced allergic airway inflammation (AAI). In silico predicted target genes were confirmed in reporter assays and in house-dust-mite (HDM) induced AAI and primary human bronchial epithelial cells (NHBE) cultured at the air-liquid interface...

Antiviral responses must rapidly defend against infection while minimizing inflammatory damage, but the mechanisms that regulate the magnitude of response within an infected cell are not well understood. miRNAs are small non-coding RNAs that suppress protein levels by binding target sequences on their cognate mRNA. Here, we identify miR-144 as a negative regulator of the host antiviral response. Ectopic expression of miR-144 resulted in increased replication of three RNA viruses in primary mouse lung epithelial cells: influenza virus, EMCV, and VSV...

BACKGROUND: Expression of host microRNAs (miRNAs) changes markedly during influenza A virus (IAV) infection of natural and adaptive hosts, but their role in genetically determined host susceptibility to IAV infection has not been explored. We, therefore, compared pulmonary miRNA expression during IAV infection in two inbred mouse strains with differential susceptibility to IAV infection. RESULTS: miRNA expression profiles were determined in lungs of the more susceptible strain DBA/2J and the less susceptible strain C57BL/6J within 120 h post infection (hpi) with IAV (H1N1) PR8...

INTRODUCTION: Non-small cell lung cancer (NSCLC) is the most common subtype of lung cancer. One of the signal transduction pathways related to NSCLC is Unfolded Protein Response (UPR), which is mainly regulated by GRP78 (HSPA5, Gene ID: 3309). The aim of this study was to employ bioinformatics tools to predict microRNAs (miRNAs) affecting GRP78 expression, experimentally validate interaction of these miRNAs with GRP78 and also evaluating the expression correlation of GRP78 and its predicted miRNAs in clinical samples...

Lung cancer is a major human malignancy. Nowadays, the lack of specific diagnostic marker of lung cancer restricts the early diagnosis and therapy of patients. Exosomes, as spherical 30-100 nm microvesicles, are released by normal and cancer cells in both physiological and pathological circumstances. Exosomes carry various molecular cargos such as miRNA, proteins, mRNA, DNA and lipids. Therefore, analysis the molecular profiles of exosomes may provide beneficial biomarkers for disease diagnosis. Exosomes can be transported by body fluids...

The number of new lung cancer cases diagnosed yearly is high, and the mortality rate has not substantially declined. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, and adenocarcinoma accounts for the largest proportion of NSCLC. Currently, platinum-based combined chemotherapy, particularly cisplatin (DDP) is still the main form of treatment for advanced NSCLC. However, cisplatin resistance often occurs in patients who receive chemotherapy. Previous studies offer various explanations for how miRNAs affect cisplatin resistance, but the underlying mechanism remains largely unknown...

There are many classes of noncoding RNAs (ncRNAs), with wide-ranging functionalities (e.g., RNA editing, mediation of mRNA splicing, ribosomal function). MicroRNAs (miRNAs) and long ncRNAs (lncRNAs) are implicated in a wide variety of cellular processes, including the regulation of gene expression. Incorrect expression or mutation of lncRNAs has been reported to be associated with several disease conditions, such a malignant transformation in humans. Importantly, pivotal players in tumorigenesis and cancer progression, such as c-Myc, may be regulated by lncRNA at promoter level...
