TERRA and RAD51AP1 promote alternative lengthening of telomeres through an R-to D-loop switch

T Yadav, JM Zhang, J Ouyang, W Leung, A Simoneau… - Molecular cell, 2022 - cell.com
Alternative lengthening of telomeres (ALT), a telomerase-independent process maintaining
telomeres, is mediated by break-induced replication (BIR). RAD52 promotes ALT by …

TERRA transcripts localize at long telomeres to regulate telomerase access to chromosome ends

N Bettin, E Querido, I Gialdini, GP Grupelli, E Goretti… - Science …, 2024 - science.org
The function of TERRA in the regulation of telomerase in human cells is still debated. While
TERRA interacts with telomerase, how it regulates telomerase function remains unknown …

The ARID1A-METTL3-m6A axis ensures effective RNase H1-mediated resolution of R-loops and genome stability

J Zhang, F Chen, M Tang, W Xu, Y Tian, Z Liu, Y Shu… - Cell Reports, 2024 - cell.com
R-loops are three-stranded structures that can pose threats to genome stability. RNase H1
precisely recognizes R-loops to drive their resolution within the genome, but the underlying …

Looping out of control: R-loops in transcription-replication conflict

C Kumar, D Remus - Chromosoma, 2024 - Springer
Transcription-replication conflict is a major cause of replication stress that arises when
replication forks collide with the transcription machinery. Replication fork stalling at sites of …

Regulation and function of R-loops at repetitive elements

A Gambelli, A Ferrando, C Boncristiani, S Schoeftner - Biochimie, 2023 - Elsevier
R-loops are atypical, three-stranded nucleic acid structures that contain a stretch of RNA:
DNA hybrids and an unpaired, single stranded DNA loop. R-loops are physiological relevant …

R-loops at chromosome ends: from formation, regulation, and cellular consequence

Y Gong, Y Liu - Cancers, 2023 - mdpi.com
