CpERF‐WRI1 Manipulates Ethylene Sensing by Regulating the Expression of CpERS1 and Fruit Ripening in Papaya

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Ethylene plays a crucial role in fruit ripening and is perceived by specialised receptor proteins embedded in the endoplasmic reticulum (ER) membrane. As an ethylene antagonist, 1‐methylcyclopropene (1‐MCP) binds to these receptors and delays papaya ripening, but improper use can cause ripening disorders.

Nucleosome wrapping states encode principles of 3D genome organization

open access: yesNature Communications
Nucleosome is the basic structural unit of the genome. During processes like DNA replication and gene transcription, the conformation of nucleosomes undergoes dynamic changes, including DNA unwrapping and rewrapping, as well as histone disassembly and ...

ASF1 Proteins are Involved in UV-induced DNA Damage Repair and are Cell Cycle Regulated by E2F Transcription Factors in Arabidopsis thaliana [PDF]

open access: yes, 2013
ASF1 is a key histone H3/H4 chaperone that participates in a variety of DNA and chromatin-related processes, including DNA repair, where chromatin assembly and disassembly is of primaryrelevance.

Tousled kinase TLK1B counteracts the effect of Asf1 in inhibition of histone H3–H4 tetramer formation [PDF]

open access: yes, 2009
Background The Tousled-like kinases (TLKs) function in processes of chromatin assembly, including replication, transcription, repair, and chromosome segregation.

Quantitative single-molecule microscopy reveals that CENP-A(Cnp1) deposition occurs during G2 in fission yeast [PDF]

open access: yes, 2012
The inheritance of the histone H3 variant CENP-A in nucleosomes at centromeres following DNA replication is mediated by an epigenetic mechanism. To understand the process of epigenetic inheritance, or propagation of histones and histone variants, as ...

Hypoxia and the cytoskeleton

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

The Structural Basis of Gene Regulation for DNA Organized as Chromatin

open access: yesCHIMIA, 2001
DNA in the nucleus of eukaryotic cells is organized in chromatin, a nucleoprotein complex containing roughly half DNA and half protein. The nucleosome is the underlying DNA packaging element in chromatin, repeating approximately every 200 base ...

Structure, localization and histone binding properties of nuclear-associated nucleosome assembly protein from Plasmodium falciparum

open access: yesMalaria Journal, 2010
Background Nucleosome assembly proteins (NAPs) are histone chaperones that are crucial for the shuttling and incorporation of histones into nucleosomes.

Application of advanced fluorescence microscopy to the structure of meiotic chromosomes [PDF]

open access: yes, 2013
Chromosomes undergoing meiosis are defined by a macromolecular protein assembly called the synaptonemal complex which holds homologs together and carries out important meiotic functions.

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on
