R-loops as cellular regulators and genomic threats

MP Crossley, M Bocek, KA Cimprich - Molecular cell, 2019 - cell.com
During transcription, the nascent RNA strand can base pair with its template DNA, displacing
the non-template strand as ssDNA and forming a structure called an R-loop. R-loops are …

METTL3 and N6-methyladenosine promote homologous recombination-mediated repair of DSBs by modulating DNA-RNA hybrid accumulation

C Zhang, L Chen, D Peng, A Jiang, Y He, Y Zeng… - Molecular cell, 2020 - cell.com
Double-strand breaks (DSBs) are the most deleterious DNA lesions, which, if left unrepaired,
may lead to genome instability or cell death. Here, we report that, in response to DSBs, the …
