This meeting will integrate mechanistic insights from biochemical studies with cellular pathways that control DNA replication initiation and progression, DNA recombination, and responses to DNA damage. Organized by: Keystone Symposia on Molecular and Cellular Biology Deadline for abstracts/proposals: 27th October 2010 2000-10-27 · Abstract. During meiosis in Saccharomyces cerevisiae, DNA replication occurs 1.5 to 2 hours before recombination initiates by DNA double-strand break formation.We show that replication and recombination initiation are directly linked. Blocking meiotic replication prevented double-strand break formation in a replication-checkpoint–independent manner, and delaying replication of a chromosome ... DNA replication, recombination, and repair, individually, have been important subjects of molecular biology since its emergence, but we have recently become aware that the 3Rs are actually much more intimately related to one another than we used to realize. Furthermore, the 3R research fields have been growing even This mixture was centrifuged, with heavy DNA settling to the bottom and light DNA to the top. As time went on, The N-15 band disappeared and the N-14 band became more visible, suggesting that newly replicated DNA was more numerous than old DNA. This made conservative replication an impossibility. Homologous recombination is a universal mechanism that allows DNA repair and ensures the efficiency of DNA replication. The substrate initiating the process of homologous recombination is a single-stranded DNA that promotes a strand exchange reaction resulting in a genetic exchange that promotes genetic diversity and DNA repair.

I. Murfuni, U. Rass, in DNA Repair in Cancer Therapy (Second Edition), 2016. Abstract. Homologous recombination (HR) is a molecular pathway involved in a multitude of processes, from the generation of genetic diversity to DNA repair and replication. HR provides a mechanism for the accurate repair of DNA double-strand breaks, protecting cells from chromosomal aberrations such as those seen in ... By doing this, the DNA damage checkpoint limits further formation of recombinogenic ssDNA gaps caused by ongoing DNA replication in the presence of DNA damage. Rad51 catalyzes the early strand invasion step of homologous recombination repair of ssDNA gaps, and, through its ability to displace RPA, deactivates the checkpoint signal. Recombination is one mechanism that may repair DNA breaks and reestablish stalled replication forks. The events of S phase are closely linked with the later events of the cell cycle. As described above, maintenance of the order of the cell cycle and alternation of S phase with mitosis preserves the genome integrity.

Surprisingly, the srs2-K41A protein forms fewer replication and recombination foci than wild-type Srs2 protein (unpublished data), suggesting that the process blocked by this mutant protein occurs either before Srs2 focus formation or, alternatively, that the residence time of this protein is shorter in the absence of ATP binding and hydrolysis. DNA can be damaged as a result of failures during replication or exposure to damage‐inducing agents at any stage of the cell cycle. One of the most genotoxic lesions is a DNA double‐strand break (DSB). Nonhomologous end‐joining (NHEJ) and homologous recombination are the principal pathways responsible for repairing DSBs in eukaryotes. 2014-12-12 · Replication factor A (RPA) is a single-strand DNA binding protein involved in DNA replication, recombination and repair processes. It is composed by the subunits RPA-1, RPA-2 and RPA-3; the major DNA-binding activity resides in the subunit 1 of the heterotrimeric RPA complex. In yeast and higher eukaryotes, besides the three basic structural DNA-binding domains, the RPA-1 subunit contains an N ...

DNA Replication and Recombination. For this conference DNA Replication is the first & most vital topic to be discussed. DNA Replication which is the basis of biological inheritance starts with the division of a cell into two daughter cells and in this process a double stranded DNA molecule is copied to generate two identical copies of DNA. A clear trend of this exciting meeting was a further shift from 'ovals and arrows' models to a more mechanistic understanding of the processes underlying DNA replication and recombination. This shift has been made possible in part by a growing number of solved protein structures, often in complex with DNA, and elegant single-molecule approaches. The Keystone Symposia “DNA Replication and Recombination” meeting has historically been one of the premiere meetings in this field and one of the very few that brings together scientists working in replication and recombination across all life forms.

We are looking forward to a broad-based meeting, and abstracts are welcomed on all aspects of replication of DNA and genomic ... In contrast to the wealth of biochemical detail on DNA replication in these diverse systems, the sessions on recombination were rather sparse. Frank Stahl remarked on this disparity in his summary and predicted that the meeting, despite (or perhaps because of) the relative backwardness of research on the molecular mechanisms of recombination, would mark a watershed in studies of recombination.

Alkylating-based drugs such as TMZ and radiotherapy can promote DNA replication fork stall; this DNA damage is resolved by HR, leading to tumor recurrence. 8, 9 In our study, salinomycin showed its greatest benefit when combined with IR. Significant synergy was ... As replication failures seem to be the main source of recombinogenic DSBs, our actual view is that the major mechanism by which transcription stimulates recombination is via DSBs or ssDNA gaps potentially generated by the difficulties of the DNA replication fork to progress through transcribed DNA sequences (Aguilera and Gomez-Gonzalez 2008; Bermejo et al. 2012).
