A general highly efficient synthesis of biocompatible rhodamine dyes and probes for live-cell multicolor nanoscopy

open access: yesNature Communications, 2023
Rhodamines are privileged fluorescent dyes for labelling intracellular structures in living cells. Here, the authors present a facile protecting-group-free synthesis permitting generation of a wide range of symmetrical and unsymmetrical 4 ...

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].

TelNet - a database for human and yeast genes involved in telomere maintenance

open access: yesBMC Genetics, 2018
Background The ends of linear chromosomes, the telomeres, comprise repetitive DNA sequences in complex with proteins that protects them from being processed by the DNA repair machinery.

Structural basis of RNA polymerase II transcription on the chromatosome containing linker histone H1

open access: yesNature Communications, 2022
The mechanism by which RNAPII transcribes the DNA in the chromatosome with H1 has remained enigmatic. Here the authors present the cryo-EM structures of the RNAPII-chromatosome complexes, and explain how RNAPII is regulated by H1 in chromatin.

Targeting the Nucleosome Acidic Patch by Viral Proteins: Two Birds with One Stone?

open access: yesmBio, 2022
The past decade illuminated the H2A-H2B acidic patch as a cornerstone for both nucleosome recognition and chromatin structure regulation. Higher-order folding of chromatin arrays is mediated by interactions of histone H4 tail with an adjacent nucleosome ...

Chromatin status and transcription factor binding to gonadotropin promoters in gonadotrope cell lines. [PDF]

open access: yes, 2017
BackgroundProper expression of key reproductive hormones from gonadotrope cells of the pituitary is required for pubertal onset and reproduction. To further our understanding of the molecular events taking place during embryonic development, leading to ...

Chromatin Dynamics [PDF]

open access: yesAnnual Review of Biophysics, 2010
The expression patterns of many protein-coding genes are orchestrated in response to exogenous stimuli, as well as cell-type-specific developmental programs. In recent years, researchers have shown that dynamic chromatin movements and interactions in the nucleus play a crucial role in gene regulation.

Influence of M-phase chromatin on the anisotropy of microtubule asters [PDF]

open access: yes, 1996
In many eukaryotic cells going through M-phase, a bipolar spindle is formed by microtubules nucleated from centrosomes. These microtubules, in addition to being "captured" by kinetochores, may be stabilized by chromatin in two different ways: short-range

Reverse Phase-high-performance Liquid Chromatography (RP-HPLC) Analysis of Globin Chains from Human Erythroid Cells

open access: yesBio-Protocol, 2021
β-hemoglobinopathies are severe genetic disorders characterized either by the abnormal synthesis of the adult β-globin chains of the hemoglobin (Hb) tetramer (βS-globin chains) in sickle cell disease (SCD) or by the reduced β-globin production in β ...

ATP-dependent chromatosome remodeling [PDF]

open access: yes, 2008
Chromatin serves to package, protect and organize the complex eukaryotic genomes to assure their stable inheritance over many cell generations. At the same time, chromatin must be dynamic to allow continued use of DNA during a cell's lifetime.
