BACKGROUND: Colorectal cancer (CRC) is a common and lethal disease in which distant metastasis remains the primary cause of death. Paradoxical roles of LOX have been reported in CRC, and the intracellular function of LOX has also recently been determined. Correlations of LOX expression and its intracellular localization with clinicopathological features in CRC patients remain largely unknown. The aim of the present study was to explore the potential roles of LOX in CRC. METHODS: LOX messenger RNA expression was assayed by quantitative PCR in eight paired normal mucosa and tumor tissues...

Expression of Receptor for Hyaluronic Acid Mediated Motility (RHAMM) increases cellular motility and RHAMM overexpression promotes invasive phenotype and metastasis of cancer cells. RHAMM has been suggested as a biomarker for poor prognosis in several tumor types, including lung, breast, colorectal, gastric, pancreatic ductal, and ovarian cancers. RNA studies showed restricted RHAMM expression in normal tissues, but its protein expression data in tissues were limited. In light of its potential as a prognostic marker and a therapeutic target, we performed immunohistochemical analysis to systematically characterize RHAMM expression in normal and neoplastic human tissues...

Background: Using DNA microarrays, we previously identified 451 genes expressed in 19 different human tissues. Although ubiquitously expressed, the variable expression patterns of these "housekeeping genes" (HKGs) could separate one normal human tissue type from another. Current focus on identifying "specific disease markers" is problematic as single gene expression in a given sample represents the specific cellular states of the sample at the time of collection. In this study, we examine the diagnostic and prognostic potential of the variable expressions of HKGs in lung cancers...

Long-term heavy cigarette smoking is a well-known high-risk factor for carcinogenesis in various organs such as the head and neck, lungs, and urinary bladder. Furthermore, cigarette smoking can systemically accelerate aging, and as the result, promoting carcinogenesis via changing the host microenvironment. Various inflammatory factors, hormones, and chemical mediators induced by smoking mediate carcinoma-related molecules and induce carcinogenesis. MicroRNAs (miRNAs) are a family of short noncoding RNA molecules that bind to mRNAs and inhibit their expression...

Circular RNAs (circRNAs) are a group of non-protein-coding RNAs that are generated from back-splicing. Recent evidence indicates that circRNAs play important roles in tissue development, gene regulation, and carcinogenesis. It was recently demonstrated that circular RNAs can function as sponges for miRNAs. In our study, the clinical implications of circRNF13 were assessed in 50 pathologically diagnosed lung adenocarcinoma samples and their paired peripheral normal lung tissues by using quantitative polymerase chain reaction...

BACKGROUND: Emissions from diesel vehicles and biomass burning are the principal sources of primary ultrafine particles (UFP). The exposure to UFP has been associated to cardiovascular and pulmonary diseases, including lung cancer. Although many aspects of the toxicology of ambient particulate matter (PM) have been unraveled, the molecular mechanisms activated in human cells by the exposure to UFP are still poorly understood. Here, we present an RNA-seq time-course experiment (five time point after single dose exposure) used to investigate the differential and temporal changes induced in the gene expression of human bronchial epithelial cells (BEAS-2B) by the exposure to UFP generated from diesel and biomass combustion...

Lung cancer characterized with malignant cell growth is the leading cause of cancer-related deaths. In recent years, several circular RNAs (circRNAs) have been reported to participate in lung cancer progression. However, the correlation between circular RNA (circRNA) and lung cancer still remains to be further investigated. In this study, we screened out a highly expressed circular RNA hsa_circRNA_103809 in lung cancer tissues. We showed hsa_circRNA_103809 could serve as a prognostic biomarker for patients with lung cancer...

LncRNAs can exhibit crucial roles in the development of multiple cancers, including non-small cell lung cancer (NSCLC). Currently, we investigated the role of lncRNA H19 in NSCLC. In our study, it was found that H19 was upregulated in A549 and H1299 cells compared to normal lung epithelial BEAS-2B cells. Meanwhile, we observed that miR-17 was downregulated in NSCLC cell lines. Inhibited H19 can suppress the growth, migration, and invasion of NSCLC cells and bioinformatics search was performed to predict the correlation between H19 and miR-17...

Circular RNAs (circRNAs) play a crucial role in the occurrence of several diseases including cancers. However, little is known about their role in Non-small cell lung cancer (NSCLC). In the present study, we found that hsa_circ_0075930 expression levels were significantly higher in NSCLC cell lines and tissues. The elevated hsa_circ_0075930 expression was correlated with tumor size (P = 0.001) and Lymph node metastasis (P = 0.038). Functional experiments showed knockdown of hsa_circ_0075930 followed by RNA silencing restrained cell proliferation and induced cell cycle arrest of NSCLC cells...
