DNA2 and FANCM function in two distinctive pathways in disrupting TERRA R-loops and suppressing replication stress at ALT telomeres

Ashwin Ragupathi, Heba Zuhair Abid, Yun Chen…·Dong Zhang

This study shows DNA2 and FANCM function in distinct pathways to suppress replication stress at ALT telomeres, with their combined depletion causing synthetic lethality in ALT+ cancers.
