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 ...

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 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.

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 ...

Chromatin Hydrodynamics [PDF]

open access: yesBiophysical Journal, 2014
Following recent observations of large scale correlated motion of chromatin inside the nuclei of live differentiated cells, we present a hydrodynamic theory-the two-fluid model-in which the content of a nucleus is described as a chromatin solution with the nucleoplasm playing the role of the solvent and the chromatin fiber that of a solute. This system

Spermatid-specific linker histone HILS1 is a poor condenser of DNA and chromatin and preferentially associates with LINE-1 elements

open access: yesEpigenetics & Chromatin, 2018
Background Linker histones establish and maintain higher-order chromatin structure. Eleven linker histone subtypes have been reported in mammals. HILS1 is a spermatid-specific linker histone, and its expression overlaps with the histone–protamine ...

Transposable Element Dynamics and Regulation during Zygotic Genome Activation in Mammalian Embryos and Embryonic Stem Cell Model Systems

open access: yesStem Cells International, 2021
Transposable elements (TEs) are mobile genetic sequences capable of duplicating and reintegrating at new regions within the genome. A growing body of evidence has demonstrated that these elements play important roles in host genome evolution, despite ...

Investigation of the acetic acid stress response in Saccharomyces cerevisiae with mutated H3 residues

open access: yesMicrobial Cell, 2023
Enhanced levels of acetic acid reduce the activity of yeast strains employed for industrial fermentation-based applications. Therefore, unraveling the genetic factors underlying the regulation of the tolerance and sensitivity of yeast towards acetic acid
