Histone modifications are important epigenetic regulators and play a critical role in development. The targeting mechanism for histone modifications is complex and still incompletely understood. Here we applied a computational approach to predict genome-scale histone modification targets in humans by the genomic DNA sequences using a set of recent ChIP-seq data. We found that a number of histon...

The epigenetic factors causing competence differences between SN (surrounded nucleolus) and NSN (non-surrounded nucleolus) oocytes, the significance for the increased histone acetylation and methylation in SN oocytes, and whether chromatin configuration or histone modification determines oocyte competence, are unclear. This study has addressed these issues by using the ovary-holding (OH) stress...

Chromatin dynamics across cellular differentiation states is an emerging perspective from which the mechanism of global gene expression regulation may be better understood. While the roles of some histone marks have been partially interpreted in terms of their association with gene transcription, the dynamics of histone marks from a loci-specific perspective during cellular differentiation is n...

lncrnas (long non-coding rnas) are responsible to control the degradation process, rna stability, orchestration, inhibition, transcription and histone modification etc. these rnas have been termed as the key agents of several mechanisms such as development, organogenesis and regeneration of damaged tissues etc. they interact with a number of partner molecules either protein, rnas or dnas and co...

In eukaryotes, histone acetylation and methylation have been known to be involved in regulating diverse developmental processes and plant defense. These histone modification events are controlled by a series of histone modification gene families. To date, there is no study regarding genome-wide characterization of histone modification related genes in citrus species. Based on the two recent seq...

We present a modified native chromatin immunoprecipitation sequencing (ChIP-seq) experimental protocol compatible with a Gaussian mixture distribution based analysis methodology (nucleosome density ChIP-seq; ndChIP-seq) that enables the generation of combined measurements of micrococcal nuclease (MNase) accessibility with histone modification genome-wide. Nucleosome position and local density, ...

Increasing evidence suggests that histone posttranslational modifications (PTMs) function in a combinatorial fashion to regulate the diverse activities associated with chromatin. Yet how these patterns of histone PTMs influence the adapter proteins known to bind them is poorly understood. In addition, how histone-specific antibodies are influenced by these same patterns of PTMs is largely unkno...

Reprogramming is a process of transforming differentiated cells into pluripotent stem cells by inducing specific modifying factors in the cells. Reprogramming is a non-equilibrium process involving a collaboration at levels separated by orders of magnitude in time scale, namely transcription factor binding/unbinding, protein synthesis/degradation, and epigenetic histone modification. We propose...

Histone modifications are important markers of function and chromatin state, yet the DNA sequence elements that direct them to specific genomic locations are poorly understood. Here, we identify hundreds of quantitative trait loci, genome-wide, that affect histone modification or RNA polymerase II (Pol II) occupancy in Yoruba lymphoblastoid cell lines (LCLs). In many cases, the same variant is ...

Histone acetylation modification significantly affects secondary metabolism in filamentous fungi. However, how histone regulates metabolite synthesis the lovastatin (a lipid-lowering drug) producing Aspergillus terreus remains unknown because protein is involved and has been identified this species. Here, fungal-specific deacetylase gene, hstD, was characterized through functional genomics two ...
