Considerable effort has been invested in the development of sophisticated technologies enabling detection of clinically significant low-level tumor specific KRAS mutations. Coamplification at lower denaturation temperature-PCR (COLD-PCR) is a new form of PCR that selectively amplifies mutation-containing templates based on the lower melting temperature of(More)
Numerous genetic and epigenetic events driving tumorigenesis have been characterized. However, knowledge is lacking on the particular events required for the metastatic spread of cancer cells. The engulfment and cell motility 3 (ELMO3) gene plays an important role for the migratory potential of cells, but have not previously been studied in primary samples(More)
Numerous sophisticated high-throughput sequencing technologies have been developed over the past decade, and these have enabled the discovery of a diverse catalog of small non-coding (nc)RNA molecules that function as regulatory entities by associating with Argonaute (Ago) proteins. MicroRNAs (miRNAs) are currently the best-described class of(More)
Over the last decades, it has become evident that highly complex networks of regulators govern post-transcriptional regulation of gene expression. A novel class of Argonaute (Ago)-associated RNA molecules, the agotrons, was recently shown to function in a Drosha- and Dicer-independent manner, hence bypassing the maturation steps required for canonical(More)
Readily accessible formalin-fixed paraffin embedded (FFPE) tissues are a highly valuable source of genetic material for molecular analyses in both research and in vitro diagnostics but frequently genetic material in those samples is highly degraded. With locus-specific methylation changes being widely investigated for use as biomarkers in various aspects of(More)
Lung cancer is the number one cause of cancer-related deaths worldwide. DNA methylation is an epigenetic mechanism that regulates gene expression, and disease-specific methylation changes can be targeted as biomarkers. We have compared the genome-wide methylation pattern in tumor and tumor-adjacent normal lung tissue from four lung adenocarcinoma (LAC)(More)
The majority of lung cancer deaths are caused by metastatic disease. MicroRNAs (miRNAs) are posttranscriptional regulators of gene expression and miRNA dysregulation can contribute to metastatic progression. Here, small RNA sequencing was used to profile the miRNA and piwi-interacting RNA (piRNA) transcriptomes in relation to lung cancer metastasis. RNA-seq(More)
