(Submitter supplied) The major cause of cancer-related deaths in lung cancer patients is commonly attributed to its ability to metastasize to distant organs such as the bone, brain, liver and adrenal glands. The dysregulation in miRNA expression is believed to contribute toward the initiation and progression of metastasis through their capability to regulate target genes. In this study, two NSCLC sub-cell lines possessing opposing migration and invasion properties were established using serial transwell invasion assays, followed by miRNA microarray to obtain the overview of miRNA expression as well as identify important playes in metastasis.

(Submitter supplied) Bcl-xL is an anti-apoptotic protein that is frequently found to be overexpressed in non-small cell lung cancer leading to an inhibition of apoptosis and poor prognosis. Recently, the role of miRNAs in regulating apoptosis and cell survival during tumorigenesis has become evident, with cancer cells showing perturbed expression of various miRNAs. We utilized miRNA microarrays to determine if miRNA dysregulation in bcl-xL silenced lung adenocarcinoma cells could be involved in regulating apoptotic behavior, and identified dysregulated miRNAs with putative targets involved in signal transduction pathways regulating apoptosis, cell proliferation and cell progression.

(Submitter supplied) Background: Claudin-1(CLDN1), one of the key components of tight junction proteins, was found to be down-regulated in human lung adenocarcinomas. This study we investigated the clinical significance of CLDN1 expression in lung adenocarcinoma patients and its role in cancer progression. Method: CLDN1 mRNA expression was measured in tumor specimens from 51 patients with lung adenocarcinoma. CLDN1 protein expression was also examined by immunohistochemistry on specimens from an independent cohort of 67 lung adenocarcinoma patients. more...

Analysis of lung adenocarcinoma CL1-5 cells overexpressing Claudin-1 (CLDN1), a component of tight junction complexes. Low CLDN1 expression in lung adenocarcinomas is associated with shorter overall survival. Results provide insight into the role of CLDN1 in the progression of lung adenocarcinoma.

(Submitter supplied) MicroRNAs (miRNAs) participate in many biological processes and have emerged as key players in carcinogenesis. In order to identify changes in miRNAs specific for betelquid-associated oral squamous cell carcinoma (OSCC), we investigated the expression profiles of 858 miRNAs in a panel of 40 pairs of OSCC specimens and their matched non-tumorous epithelial counterparts. Eighty-four miRNAs were differentially expressed in the OSCC specimens compared to the matched tissue. more...

(Submitter supplied) Alpha-parvin (PARVA) is known to involve in the linkage of integrins, regulation of actin cytoskeleton dynamics, and cell survival. However, the role of PARVA in cancer progress is still unclear. Here, we identify PARVA as a potential oncogene from a lung cancer invasion cell line model by expression microarrays. Overexpression of PARVA enhances cell invasion, colony formation ability, and endothelial cell tube formation but knockdown of PARVA inhibits invasion and tube formation in vitro. more...
