Background The 3D organization of the chromatin fiber in cell nuclei plays a key role in the regulation of gene expression. Genome-wide techniques to score DNA-DNA contacts, such as Hi-C, reveal the partitioning of chromosomes into epigenetically defined

An holomorphic study of the Smarandache concept in loops [PDF]
If two loops are isomorphic, then it is shown that their holomorphs are also isomorphic.

CTCF mediates the cell-type specific spatial organization of the Kcnq5 locus and the local gene regulation. [PDF]
Chromatin loops play important roles in the dynamic spatial organization of genes in the nucleus. Growing evidence has revealed that the multivalent functional zinc finger protein CCCTC-binding factor (CTCF) is a master regulator of genome spatial ...

A Pair of Smarandachely Isotopic Quasigroups and Loops of the Same Variety [PDF]
The isotopic invariance or universality of types and varieties of quasigroups and loops described by one or more equivalent identities has been of interest to researchers in loop theory in the recent past.

Friedreich ataxia (FRDA) and Fragile X syndrome (FXS) are among 40 diseases associated with expansion of repeated sequences (TREDs). Although their molecular pathology is not well understood, formation of repressive chromatin and unusual DNA structures ...

Chromatin: A Connection Between Loops and Barriers? [PDF]
A genetic screen for proteins that can block the spread of silenced heterochromatin has identified components of the nuclear pores with potential barrier activity. These results suggest that formation of loops of chromatin anchored to the pore could be one mechanism of barrier function.

Pericentric Chromatin Is Organized into an Intramolecular Loop in Mitosis [PDF]
Cohesin proteins link sister chromatids and provide the basis for tension between bi-oriented sister chomatids in mitosis. Cohesin is concentrated at the centromere region of the chromosome despite the fact that sister centromeres can be separated by 800nm in vivo. The function of cohesin at sites of separated DNA is unknown.

LASCA: loop and significant contact annotation pipeline
Chromatin loops represent one of the major levels of hierarchical folding of the genome. Although the situation is evolving, current methods have various difficulties with the accurate mapping of loops even in mammalian Hi-C data, and most of them fail ...

Multi-scale phase separation by explosive percolation with single-chromatin loop resolution
The 2 m-long human DNA is tightly intertwined into the cell nucleus of the size of 10 μm. The DNA packing is explained by folding of chromatin fiber.
