Nature research paper: Evidence for improved DNA repair in long-lived bowhead whale

Evidence for improved DNA repair in long-lived bowhead whale - Nature
Analysis of the longest-lived mammal, the bowhead whale, reveals an improved ability to repair DNA breaks, mediated by high levels of cold-inducible RNA-binding protein.

The enzyme cGAS senses DNA damage, but in humans and mice it inhibits a DNA repair pathway (homologous recombination), which reduces genome stability. In naked mole-rats, altering 4 amino acids in cGAS changes its role: instead of hampering repair, it boosts it.

A cGAS-mediated mechanism in naked mole-rats potentiates DNA repair and delays aging
Efficient DNA repair might make possible the longevity of naked mole-rats. However, whether they have distinctive mechanisms to optimize functions of DNA repair suppressors is unclear. We find that na...

🚨The paper from my postdoc in @graeffjohannes.bsky.social’s lab at @epfl-brainmind.bsky.social is out! We show that memories can be switched on and off by simply changing the « packaging » of DNA in neurons through epigenetic editing. www.nature.com/articles/s41...
Cell-type- and locus-specific epigenetic editing of memory expression - Nature Genetics
CRISPR-based epigenetic editing is used in a cell-type-specific, locus-restricted and temporally controllable manner in the adult mouse brain to modulate memory expression.

Single-cell Micro-C profiles 3D genome structures at high resolution and characterizes multi-enhancer hubs - Nature Genetics
scMicro-C is a new method that provides high-resolution maps of the 3D genome. scMicro-C identifies structures called ‘promoter stripes’, which link a gene promoter to multiple downstream enhancers.
