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].

Pharmacological Inhibition of LSD1 for Cancer Treatment

open access: yesMolecules, 2018
Lysine-specific demethylase 1A (LSD1, also named KDM1A) is a demethylase that can remove methyl groups from histones H3K4me1/2 and H3K9me1/2. It is aberrantly expressed in many cancers, where it impedes differentiation and contributes to cancer cell ...

Idiosyncratic evolution of conserved eukaryote proteins that are similar in sequence to archaeal or bacterial proteins [PDF]

open access: yes, 2008
Sequence comparisons have been made between the proteins of 571 prokaryote species including 46 archaea and 525 bacteria and the set of human proteins.

Crosstalk Between mRNA 3'-End Processing and Epigenetics

open access: yesFrontiers in Genetics, 2021
The majority of eukaryotic genes produce multiple mRNA isoforms by using alternative poly(A) sites in a process called alternative polyadenylation (APA).

Non-mammalian model organisms in epigenetic research : an overview [PDF]

open access: yes, 2020
Recent advances in sequencing technology and genome editing tools had an indisputably enormous impact on our understanding of complex biological pathways and their genetic and epigenetic regulation.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Altered modulation of lamin A/C-HDAC2 interaction and p21 expression during oxidative stress response in HGPS [PDF]

open access: yes, 2018
Defects in stress response are main determinants of cellular senescence and organism aging. In fibroblasts from patients affected by Hutchinson-Gilford progeria, a severe LMNA-linked syndrome associated with bone resorption, cardiovascular disorders, and

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

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.

LSD1 demethylates histone and non-histone proteins [PDF]

open access: yesEpigenetics, 2009
One of the key breakthroughs in the epigenetics/chromatin field in the last several years was the identification of enzymes capable of removing the methyl group from methylated lysines in histone proteins. Lysine-specific demethylase 1 (LSD1) was the first such enzyme identified, which has been shown to demethylate histone H3 on lysine 4 (H3K4) and ...
