Ageing versus developmental silencing: Answers from the epigenome

The FEBS Journal, EarlyView.
It is easier for young animals to regenerate damaged or missing tissues. In this Viewpoint, we propose that this is, in part, attributed to epigenetic changes, with chromatin becoming more closed and inaccessible as animals age. The timing of when this occurs differs depending on the tissue—some during the late developmental stages and others at the ...

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, EarlyView.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Stemness factor Sall4 is required for DNA damage response in embryonic stem cells. [PDF]

, 2015
Mouse embryonic stem cells (ESCs) are genetically more stable than somatic cells, thereby preventing the passage of genomic abnormalities to their derivatives including germ cells. The underlying mechanisms, however, remain largely unclear. In this paper,

Establishment of transgenic Drosophila suzukii lines that express phiC31 integrase and carry the sepia gene as a marker for transformation

Insect Molecular Biology, EarlyView.
Germline transformation of the Drosophila suzukii se1 strain with the wild‐type sepia gene (~1.8 kb) using a piggyBac vector. Most lines show full rescue of sepia mutant eye colour. The lines express phage phiC31 integrase in the germline using a Dsnanos promoter.

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

Journal of Microscopy, EarlyView.
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.
