(Submitter supplied) We recently identified a subset of down-regulated miRNAs such as miR-145 and miR-133a in squamous cell carcinoma. Cell growth inhibitions occurred in miR-145 and miR-133a transfectants compared with the controls, suggesting that both miRNAs function as tumor suppressors. The aims of our expression studies were identification of these miRNAs target genes.

(Submitter supplied) We investigated whether the miRNA expression could distinguish lung cancers from normal tissues, examining 116 pairs of primary lung cancers with their corresponding adjacent normal lung tissues collected a minimum of 5 cm from the tumor. Our analysis identified a five microRNA classifier could distinguish malignant lung cancer lesions from adjacent normal tissues. SCLC could be distinguished from non small lung cancer by microRNAs profiling. more...

(Submitter supplied) Non-small-cell lung cancer (NSCLC), which is comprised mainly of adenocarcinoma and squamous cell carcinoma (SCC), is the cause of 80% of all lung cancer deaths in the US. NSCLC is also associated with a high rate of relapse following clinical treatment and therefore requires robust prognostic markers to better manage therapy options. The aim of this study was to identify miRNA expression profiles in squamous cell carcinoma (SSC) of the lung that would better predict prognosis.

(Submitter supplied) Background: Lung cancer has the highest mortality rate of all the cancers in the world and asbestos-related lung cancer is one of the leading occupational cancers. The identification of the asbestos-related molecular changes has been a topic of major research interest over the years. The aim of the current study was to identify novel asbestos-related molecular correlates by integrating miRNA expression profiling with previously obtained microarray data (aCGH and mRNA expression) from the same patient material. more...

(Submitter supplied) Dysregulated miRNA in human colorectal cancer (CRC) were identified through comparison between 4 CRC tumors and their adjacent normal tissues by miRNA array. Histologically-confirmed CRC were included in this study. CRC tissues and paired adjacent normal tissues were obtained from the resected surgical specimens. The adjacent normal tissue is composed of normal colonic mucosa located at approximately 10 cm away from the cancer tissue. more...

(Submitter supplied) Cigarette smoking is the main risk factor for the development of squamous cell lung carcinoma (SCC). However, the smoking-related molecular changes in SCC have not been studied. We wanted to identify genes in both histologically normal bronchial epithelium and SCC samples that are differentially expressed between current and ex-smokers. In addition, to analyze the levels of the smoking-related genes identified in normal bronchial epithelium with the levels in SCC. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) and squamous cell lung carcinoma (SCC) are both smoking-related diseases. Interestingly, COPD itself is a risk factor for SCC, and this is independent of smoking history. Inferring from this knowledge, it is plausible to assume that patients with COPD may have a different gene expression profile in normal bronchial epithelium and in SCC. To test this hypothesis, we compared gene expression profiles in bronchial epithelium and in SCC from patients with and without COPD. more...

(Submitter supplied) The majority of patients with squamous cell lung cancer (SCC) die because of metastatic disease. The genomic mechanisms underlying this metastatic behaviour are underexposed. We analyzed a cohort of patients with primary squamous cell carcinoma (SCC) using array-based comparative genomic hybridization (aCGH) to identify which genomic aberrations were related metastatic behaviour. The cohort consisted of 34 patients with a follow-up of at least 5 years, including 15 without any metastases, 8 with metastases in regional lymph nodes only, and 11 with metastases exclusively in distant organs within two years after surgery. more...

Analysis of DU145 prostate cancer cells with restored miR-205 expression. miR-205 expression is lower in prostate cancer cell lines than in normal cell lines, as well as in prostate tumors than in matched normal prostate tissues. Results provide insight into the role of miR-205 in prostate cancer.

(Submitter supplied) Abstract: Altered expression of microRNAs (miRNAs) is associated with development and progression of various human cancers by regulating the translation of oncogenes and tumor suppressor genes. In colorectal cancer (CRC), these regulators complement the Vogelstein multi-step model of pathogenesis and have the potential of becoming a novel class of tumor biomarkers and therapeutic targets. Using QRT-PCR, we measured the expression of 621 mature miRNAs in 40 CRCs and their paired normal tissues and identified 23 significantly deregulated miRNAs. more...
