Human DNA replication initiation sites are specified epigenetically by oxidation of 5-methyl-deoxycytidine

T Krude, J Bi, R Doran, RA Jones, JC Smith - bioRxiv, 2024 - biorxiv.org
DNA replication initiates at tens of thousands of sites on the human genome during each S
phase. However, no consensus DNA sequence has been found that specifies the locations …

Nuclear DNA replication in Leishmania major relies on a single constitutive origin per chromosome supplemented by thousands of stochastic initiation events

JD Damasceno, GLA Silva, CA Marques… - bioRxiv, 2024 - biorxiv.org
Understanding genome duplication requires characterisation of the locations where DNA
replication initiates, termed origins. Genome-wide mapping of DNA replication origins has …

Regulation of replication timing in Saccharomyces cerevisiae

R Berners-Lee, E Gilmore, F Berkemeier, MA Boemo - bioRxiv, 2024 - biorxiv.org
In order to maintain genomic integrity, DNA replication must be highly coordinated.
Disruptions in this process can cause replication stress which is aberrant in many …

ATR and TopBP1 oppose to control dormant origin building, providing a first defence against replication stress

M Debatisse, S Koundrioukoff, S Kim, N Alary… - 2024 - researchsquare.com
Replication stress, a major hallmark of cancers, sources from replication fork slowing or
blocking. In response, activation of extra-origins, otherwise dormant, supports the replication …
