"Direct" and "Indirect" Effects of Histone Modifications: Modulation of Sterical Bulk as a Novel Source of Functionality.

The chromatin-regulatory principles of histone post-translational modifications (PTMs) are discussed with a focus on the potential alterations in chromatin functional state due to steric and mechanica...

The intrinsic stability of H2B-ubiquitylated nucleosomes and their in vitro assembly/disassembly by histone chaperone NAP1.

Apart the gene-regulatory functions as docking sites for histone 'readers', some histone modifications could directly affect nucleosome structure. The H2BK34-ubiquitylation deposited by MOF-MSL comple...

Glutarylation of Histone H4 Lysine 91 Regulates Chromatin Dynamics.

Histone posttranslational modifications (PTMs) regulate chromatin structure and dynamics during various DNA-associated processes. Here, we report that lysine glutarylation (Kglu) occurs at 27 lysine r...

Structural transition of the nucleosome during chromatin remodeling and transcription.

In eukaryotes, the nucleosome is the basic unit of chromatin. Since the genomic DNA is tightly wrapped around the histone octamer in the nucleosome, its function is severely restricted in chromatin. T...

High-resolution and high-accuracy topographic and transcriptional maps of the nucleosome barrier.

Nucleosomes represent mechanical and energetic barriers that RNA Polymerase II (Pol II) must overcome during transcription. A high-resolution description of the barrier topography, its modulation by e...

Epigenetic Regulation of Immunity in Alpha-1 Anti-trypsin Deficiency

The investigators hypothesize that environmentally influenced histone modifications regulate AM mediated inflammation, contributing to a variable clinical course of AATD, and may also infl...

Study of Vorinostat Plus Capecitabine (X) and Cisplatin (P) for 1st Line Treatment of Metastatic or Recurrent Gastric Cancer

There is scientific rationale for exploring the role of vorinostat, histone deacetylase inhibitor with capecitabine (X) and cisplatin (P), one of standard chemotherapy in patients with adv...

IVUS Controlled Stenting

Stent placement is now widely accepted to improve the results of angioplasty (an operation to widen the blood vessel) and decreasing the need for further surgery. Despite their worldwide a...

HIV-DNA Dynamics in HIV Monoinfected or HIV/HCV Coinfected Patients

New markers of viral activity are now under investigation. Aim of the study is to investigate the efficacy of new antiretroviral drugs by monitoring HIV-DNA dynamics in HIV-positive popula...

GRID Therapy as Palliative Radiation for Patients With Advanced and Symptomatic Tumors

Palliative radiation therapy represents 40% of the on-going radiation at the Jewish General Hospital. In a traditional palliative radiation treatment to bulky or radioresistant tumors, ra...

Medical and Biotech [MESH] Definitions

A histone chaperone that facilitates nucleosome assembly by mediating the formation of the histone octamer and its transfer to DNA.

A class II histone deacetylase that removes acetyl groups from N-terminal LYSINES of HISTONE H2A; HISTONE H2B; HISTONE H3; and HISTONE H4. It plays a critical role in EPIGENETIC REPRESSION and regulation of GENETIC TRANSCRIPTION, as well as CELL MOTILITY through deacetylation of TUBULIN. It also targets misfolded proteins for clearance by AUTOPHAGY when MOLECULAR CHAPERONE-mediated folding is overwhelmed.

A family of histone molecular chaperones that play roles in sperm CHROMATIN decondensation and CHROMATIN ASSEMBLY in fertilized eggs. They were originally discovered in XENOPUS egg extracts as histone-binding factors that mediate nucleosome formation in vitro.

A enzyme complex involved in the remodeling of NUCLEOSOMES. The complex is comprised of at least seven subunits and includes both histone deacetylase and ATPase activities.

A genetic process by which the adult organism is realized via mechanisms that lead to the restriction in the possible fates of cells, eventually leading to their differentiated state. Mechanisms involved cause heritable changes to cells without changes to DNA sequence such as DNA METHYLATION; HISTONE modification; DNA REPLICATION TIMING; NUCLEOSOME positioning; and heterochromatization which result in selective gene expression or repression.
