Depletion of ATP-citrate lyase (ATPCL) affects chromosome integrity without altering histone acetylation in Drosophila mitotic cells [PDF]

open access: yes, 2019
The Citrate Lyase (ACL) is the main cytosolic enzyme that converts the citrate exported from mitochondria by the SLC25A1 carrier in Acetyl Coenzyme A (acetyl-CoA) and oxaloacetate.

Actin and DNA protect histones from degradation by bacterial proteases but inhibit their antimicrobial activity

open access: yesFrontiers in Microbiology, 2016
Histones are small polycationic proteins located in the cell nucleus. Together, DNA and histones are integral constituents of the nucleosomes. Upon apoptosis, necrosis and infection - induced cell death, histones are released from the cell.

The reduced expression of trimethylation of histone H3 at lysine 27 in primary cutaneous mucinous carcinoma

open access: yesDermatologica Sinica, 2023
Primary cutaneous mucinous carcinoma (PCMC) is rare, and its carcinogenesis is unclear. Trimethylation of histone H3 at lysine 27 (H3K27me3) is a key regulator in chromatin remodeling-controlled transcription.

The histone database: A comprehensive resource for histones and histone fold‐containing proteins [PDF]

open access: yesProteins: Structure, Function, and Bioinformatics, 2005
AbstractTheThe Histone Database is a curated and searchable collection of full‐length sequences and structures of histones and nonhistone proteins containing histone‐like folds, compiled from major public databases. Several new histone fold‐containing proteins have been identified, including the huntingtin‐interacting protein HYPM.

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]

open access: yes, 2015
The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

Further biochemical characterization of Mycobacterium leprae laminin-binding proteins

open access: yesBrazilian Journal of Medical and Biological Research, 2001
It has been demonstrated that the alpha2 chain of laminin-2 present on the surface of Schwann cells is involved in the process of attachment of Mycobacterium leprae to these cells. Searching for M. leprae laminin-binding molecules, in a previous study we

Histone Deacetylases and Histone Deacetylase Inhibitors in Neuroblastoma [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2020
Histone deacetylases (HDACs) are enzymes that play a key role in regulating gene expression by remodeling chromatin structure. An imbalance of histone acetylation caused by deregulated HDAC expression and activity is known to promote tumor progression in a number of tumor types, including neuroblastoma, the most common solid tumor in children ...

BPA-Induced Deregulation of Epigenetic Patterns: Effects on Female Zebrafish Reproduction [PDF]

open access: yes, 2016
Bisphenol A (BPA) is one of the commonest Endocrine Disruptor Compounds worldwide. It interferes with vertebrate reproduction, possibly by inducing deregulation of epigenetic mechanisms.

Quantifying nuclear wide chromatin compaction by phasor analysis of histone Förster resonance energy transfer (FRET) in frequency domain fluorescence lifetime imaging microscopy (FLIM) data. [PDF]

open access: yes, 2020
The nanometer spacing between nucleosomes throughout global chromatin organisation modulates local DNA template access, and through continuous dynamic rearrangements, regulates genome function [1].

Chaperones and Beyond as Key Players in Pluripotency Maintenance

open access: yesFrontiers in Cell and Developmental Biology, 2019
Pluripotency is orchestrated by distinct players and chaperones and their partners have emerged as pivotal molecules in proteostasis control to maintain stemness.
