The functional and structural complexity of the myriad of cells in metazoan organisms arises from a small number of stem cells. Stem cells are characterized by two fundamental properties: self-renewal and multipotency that allows a stem cell to differentiate into virtually any cell type. The progression stem cell to differentiated cell is characterized by loss of multipotency, structural and mo...

Chromatin accessibility is tightly regulated by multiple factors/mechanisms to establish different cell type-specific gene expression programs from a single genome. Dysregulation of this process can lead to diseases including cancer. The Mi-2/nucleosome remodeling and deacetylase (NuRD) complex is thought to orchestrate chromatin structure using its intrinsic nucleosome remodeling and histone d...

This two-volume publication contains the proceedings of a NATO Advanced Study Institute, held in April 1978. The material is organized in five sections. In the first section J. Bonner presents a historic review of chromatin research. The following section describes biophysical and chemical methods used in the study of isolated chromatin, such as electron microscopy, circular dichroism, X-ray di...

A significant association between male subfertility, imperfect spermiation and abnormal nuclear condensation has been suggested. The DNA content of spermatozoa might be responsible for inducing alterations in sperm morphology. The final nuclear shape, which is species-specific, depends on chromatin condensation during spermatogenesis as well as a precise organization of DNA within the nucleus. ...

Here we describe a sensitive and novel method of identifying endogenous DNA-DNA interactions. Capture of Associated Targets on CHromatin (CATCH) uses efficient capture and enrichment of specific genomic loci of interest through hybridization and subsequent purification via complementary biotinylated oligonucleotide. The CATCH assay requires no enzymatic digestion or ligation, requires little st...

ChIA-PET2 is a versatile and flexible pipeline for analyzing different types of ChIA-PET data from raw sequencing reads to chromatin loops. ChIA-PET2 integrates all steps required for ChIA-PET data analysis, including linker trimming, read alignment, duplicate removal, peak calling and chromatin loop calling. It supports different kinds of ChIA-PET data generated from different ChIA-PET protoco...

• We propose 7 ways for nucleosome binding proteins to affect higher order structure. Choices on nucleosomal array conditions impact protein and overall Chromatin phase separation is driven by a range of interactions the nucleosome. The regulation chromatin biology ultimately depends manipulation its smallest subunit, that bind operate do so, while their substrate part polymer embedded in dense...
