Genome-Level Analysis of Selective Constraint without Apparent Sequence Conservation
Conservation of function can be accompanied by obvious similarity of homologous sequences which may persist for billions of years (Iyer LM, Leipe DD, Koonin EV, Aravind L. 2004. Evolutionary history and higher order classification of AAA+ ATPases. J Struct Biol. 146:11-31.). However, presumably homologous segments of noncoding DNA can also retain their ancestral function even after their sequen...
متن کاملDifferential DNA Methylation Analysis without a Reference Genome
Genome-wide DNA methylation mapping uncovers epigenetic changes associated with animal development, environmental adaptation, and species evolution. To address the lack of high-throughput methods for DNA methylation analysis in non-model organisms, we developed an integrated approach for studying DNA methylation differences independent of a reference genome. Experimentally, our method relies on...
متن کاملScreenTroll: a searchable database to compare genome-wide yeast screens
Systematic biological screens typically identify many genes or proteins that are implicated in a specific phenotype. However, deriving mechanistic insight from these screens typically involves focusing upon one or a few genes within the set in order to elucidate their precise role in producing the phenotype. To find these critical genes, researchers use a variety of tools to query the set of ge...
متن کاملGenome Annotation without Genes
The concept of the gene plays a fundamental role both in the interpretation and in the organization and storage of molecular biology data. Genes are treated as if they were unambiguously characterized physical entities with clearly defined measurable properties. The ubiquitous usage of genes in current bio-databases reinforces this perception. A closer look at the data models and the ongoing di...
متن کاملPredicting CpG Islands and DNA Methlation in the Cow Genome Using DNA Microarray Meta-Analysis and Genome Wide Scanning
DNA methylation is a type of epigenetic changes that directly affects DNA. In mammals, DNA methylation is essential for fetal development and stem cell differentiation and this phenomenon essentially occurs within the CpG islands. In this study, two methods were used to study the DNA methylation profile of cow genome. In the first method, the DNA methylation profile of the differentially expres...
