Genome-scale analysis of aberrant DNA methylation in colorectal cancer.
Colorectal cancer (CRC) is a heterogeneous disease in which unique subtypes are characterized by distinct genetic and epigenetic alterations. Here we performed comprehensive genome-scale DNA methylation profiling of 125 colorectal tumors and 29 adjacent normal tissues. We identified four DNA methylation-based subgroups of CRC using model-based cluster analyses. Each subtype shows characteristic...
متن کاملGenome-wide analysis of DNA methylation patterns.
Cytosine methylation is the most common covalent modification of DNA in eukaryotes. DNA methylation has an important role in many aspects of biology, including development and disease. Methylation can be detected using bisulfite conversion, methylation-sensitive restriction enzymes, methyl-binding proteins and anti-methylcytosine antibodies. Combining these techniques with DNA microarrays and h...
متن کاملAccurate genome-scale percentage DNA methylation estimates from microarray data.
DNA methylation is a key regulator of gene function in a multitude of both normal and abnormal biological processes, but tools to elucidate its roles on a genome-wide scale are still in their infancy. Methylation sensitive restriction enzymes and microarrays provide a potential high-throughput, low-cost platform to allow methylation profiling. However, accurate absolute methylation estimates ha...
متن کاملCancer Biomarkers from Genome-Scale DNA Methylation: Comparison of Evolutionary and Semantic Analysis Methods
DNA methylation profiling exploits microarray technologies, thus yielding a wealth of high-volume data. Here, an intelligent framework is applied, encompassing epidemiological genome-scale DNA methylation data produced from the Illumina's Infinium Human Methylation 450K Bead Chip platform, in an effort to correlate interesting methylation patterns with cancer predisposition and, in particular, ...
متن کاملGenome-scale meta-analysis of DNA methylation during progression of lung adenocarcinoma.
Identification of epigenetic alterations in tumors has become a common method for identifying genes critical to cancer development and progression. Thus, we identified DNA methylation alterations on the genome scale during lung adenocarcinoma (LADC) progression to understand the carcinogenic process and identify clinically relevant biomarkers. We found that epigenetic alterations in LADC mainly...
