Histones are frequently decorated with covalent modifications. These histone modifications are thought to be involved in various chromatin-dependent processes including transcription. To elucidate the relationship between histone modifications and transcription, we derived quantitative models to predict the expression level of genes from histone modification levels. We found that histone modifi...

Imagine trying to stuff about 10,000 miles of spaghetti inside a basketball. Then, if that was not difficult enough, attempt to find a unique one inch segment of pasta from the middle of this mess, or try to duplicate, untangle and separate individual strings to opposite ends. This simple analogy illustrates some of the daunting tasks associated with the transcription, repair and replication of...

Sulfur mustard (SM, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes DNA alkylation, protein modification and membrane damage. SM can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. Epigenetic regulation of gene expression is a growing research topic and is ...

differentiation of stem cells from a pluripotent to a committed state involves global changes in genome expression patterns, the best known as “epigenetic modifications”. epigenetic mechanisms, including histone modifications, dna methylation and non-coding rna-mediated regulatory events are considered as the essential factors to control the heritable cellular memory of gene expression during d...

sideration as DNA methylation patterns may be reversible and changeable under certain physiological and pathological conditions. This idea is supported by the fact that differentiated cells are still potent enough to be converted into iPS cells, presumably coupling with altered DNA methylation pattern. Beyond canonical epigenomic modification, the current view of the epigenome includes histone ...
