Distinct ATRX functions cooperate with 9-1-1 and CST complexes to safeguard replication and telomere integrity

Mutations in the ATRX chromatin remodeller predispose to a developmental genetic disorder and cancer, but how it safeguards genome and telomere stability remains unresolved. Here, we uncover critical ...

New method 🚀: scEpi2-seq lets us read DNA methylation+histone marks in the same single cell. Found that methylation “memory” after replication depends on chromatin+histones, and TF promoters repressed by H3K27me3 carry distinct methylation. So stoked to share this as first+co-corresponding author 🎉

We discovered that PARP inhibitors 💊 trigger histone eviction from the chromatin and this creates a hidden vulnerability in PARPi resistant tumors.

NASP modulates histone turnover to drive PARP inhibitor resistance - Nature

PARP inhibitor treatment triggers histone release from the chromatin in cancer cells; consequently, targeting the histone chaperone NASP renders cells vulnerable to PARP inhibition.
