Additional sex combs interacts with enhancer of zeste and trithorax and modulates levels of trimethylation on histone H3K4 and H3K27 during transcription of hsp70. [PDF]

open access: yes, 2017
BACKGROUND: Maintenance of cell fate determination requires the Polycomb group for repression; the trithorax group for gene activation; and the enhancer of trithorax and Polycomb (ETP) group for both repression and activation.

Magnetic Beads Make Chromatin Immunoprecipitation Faster and Easier

open access: yesBioTechniques, 2007
Active Motif's ChIP-IT™ Express Kits use protein G-coated magnetic beads instead of the traditionally used agarose beads to make chromatin immunoprecipitation (ChIP) faster and better than ever before.

The laminA/NF-Y protein complex reveals an unknown transcriptional mechanism on cell proliferation [PDF]

open access: yes, 2016
Lamin A is a component of the nuclear matrix that also controls proliferation by largely unknown mechanisms. NF-Y is a ubiquitous protein involved in cell proliferation composed of three subunits (-YA -YB -YC) all required for the DNA ...

Direct identification of insulator components by insertional chromatin immunoprecipitation. [PDF]

open access: yesPLoS ONE, 2011
Comprehensive understanding of mechanisms of epigenetic regulation requires identification of molecules bound to genomic regions of interest in vivo. However, non-biased methods to identify molecules bound to specific genomic loci in vivo are limited ...

Improved nuclear localization of DNA-binding polyamides [PDF]

open access: yes, 2006
Regulation of endogenous genes by DNA-binding polyamides requires effective nuclear localization. Previous work employing confocal microscopy to study uptake of fluorophore-labeled polyamides has demonstrated the difficulty of predicting a priori the ...

Native Chromatin Immunoprecipitation [PDF]

open access: yes, 2011
Native chromatin immunoprecipitation refers to a method that allows for identification and quantification of DNA that is associated with specific chromatin proteins without altering the structure of these proteins. The method has been used with great success in the past and has some advantages over the more widely used cross-linking chromatin ...

Estradiol Receptor (ER) Chromatin Immunoprecipitation in MCF-7 Cells

open access: yesBio-Protocol, 2013
Steroid hormone receptors, for example estradiol receptor, act like transcription factors. In the cell, steroids bind to a specific receptor. Upon ligand binding, many steroid receptors dimerize and enter nuclei where they bind specific DNA sequences ...

TBL1 is required for the mesenchymal phenotype of transformed breast cancer cells [PDF]

open access: yes, 2019
The epithelial-to-mesenchymal transition (EMT) and its reversion (MET) are related to tumor cell dissemination and migration, tumor circulating cell generation, cancer stem cells, chemoresistance, and metastasis formation.

Assessing the Epigenetic Status of Human Telomeres [PDF]

open access: yes, 2019
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest.

Impact of chromatin structures on DNA processing for genomic analyses. [PDF]

open access: yesPLoS ONE, 2009
Chromatin has an impact on recombination, repair, replication, and evolution of DNA. Here we report that chromatin structure also affects laboratory DNA manipulation in ways that distort the results of chromatin immunoprecipitation (ChIP) experiments. We
