A CRISPR‐Cas9‐based system for the dose‐dependent study of DNA double‐strand break sensing and repair

The FEBS Journal, EarlyView.
Using CRISPR‐Cas9, we engineered a genetic system allowing the dose‐dependent induction of a controllable number of DNA double‐strand breaks in Saccharomyces cerevisiae. The tool was used to study the kinetics of DNA break sensing and repair, including the spatial distribution of Tel1ATM kinase, which initiates the DNA damage response.

Exploring the roles of conserved context‐dependent cis‐regulatory elements (cdCREs) in multicellularity, human health and disease

The FEBS Journal, EarlyView.
Conserved context‐dependent cis‐regulatory elements act as a major reservoir of disease‐associated polymorphisms in the human genome and are also affected by epigenetic change. This ‘state‐of‐the‐art’ review explores the latest developments in studying these enigmatic elements and how the effects of disease‐associated polymorphisms and environmentally ...

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.

An Increase in Male Recombination Rate With Age in Dairy Cattle Is Heritable and Polygenic

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Meiotic recombination is an essential process for shuffling genetic diversity in sexually reproducing organisms, can vary within and between individuals in response to intrinsic and extrinsic factors, and can be heritable. Interestingly, recombination rate has been found to vary with age in some species, but to date, there have been no ...
