Optimisation of freeze substitution protocols for the examination of malaria parasite structure by volumetric electron microscopy

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 168-186, February 2026.
Abstract Malaria is one of the deadliest infectious diseases in the world, annually responsible for over 400,000 deaths. It is caused by parasites of the genus Plasmodium, which undergo remarkable structural changes during their development within different cells across various hosts.

Ethanol Alters DNMT1/3a/3b Expression Profile, Promotes Persistent DNA Hypomethylation in Human Brain Endothelial Cells and Impairs Late Cortical Angiogenesis

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
Ethanol exposure alters brain endothelial cell function and blood–brain barrier integrity. In human brain microcapillary endothelial cells (HBMEC) and mouse brain endothelial cells (MBEC) from a prenatal alcohol exposure (PAE) model, ethanol increased DNA methyltransferas‐1 (DNMT1) activity and reduced DNA methylation, affecting DNMT3a/3b, methyl‐CpG ...

Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...

Therapeutic targeting of chromatin alterations in leukemia and solid tumors

open access: yesInternational Journal of Cancer, Volume 158, Issue 2, Page 382-408, 15 January 2026.
Abstract Alterations in chromatin conformation and post‐translational modification of histones have become increasingly recognized as critical drivers of cancer development, progression, and therapy resistance. Recent advances in drug development have led to the establishment of several highly selective small molecule inhibitors, several of which are ...

Epigenetic reprogramming in multiple myeloma—Challenges and opportunities

open access: yesInternational Journal of Cancer, Volume 158, Issue 2, Page 423-432, 15 January 2026.
Abstract In cancer, mutational processes act in concert with epigenetic reprogramming to endow malignant cells with hallmark properties that underpin tumorigenesis. Compared with the relatively rigid and slow processes of genetic evolution, the plastic nature of chromatin enables cells to adapt to a changing environment more rapidly.
