Targeting the FNIP2-SERCA2b axis improves metabolic and mitochondrial defects in Ataxia Telangiectasia - Cell Death & Disease
Cell Death & Disease - Targeting the FNIP2-SERCA2b axis improves metabolic and mitochondrial defects in Ataxia Telangiectasia
Pleased to share our paper. We found surprising widespread glycogen accumulation in A-T due to mitochondrial
impairment that can be improved by targeting the unexpected FNIP2-SERCA2b-axis.

Or does NHEJ repair one strand, leaving the opposite strand for a single strand break repair pathway?

Is NHEJ truly a double-strand break repair pathway...repairing both strands, at the same time?

Base excision repair in chromatin: A tug-of-war for DNA damage
Base excision repair (BER) is a genome surveillance pathway responsible for repairing DNA base lesions distributed throughout the chromatinized eukary…
🎉 Joint paper from the Freudenthal and @tmweaver.bsky.social Labs!
Abbey Vito’s first publication discusses a tug-of-war between BER enzymes and chromatin for access to damaged DNA, a battle central to genome stability.

See our paper “Mechanism of trinucleotide repeat expansion by MutSβ-MutLγ and contraction by FAN1”. Using biochemistry, we show how DNA incisions by the MutLγ nuclease can lead to expansions, and how expansion is prevented by FAN1. Well done Issam and Valentina!

Good news for Adam, Kishore, and the Ramsden lab - their paper describing how each strand of a DSB is repaired has been accepted for pub in principle for Nature Communications. More to come on this soon...
