Synthesis and Evaluation of Biological Activities of Bis(spiropyrazolone)cyclopropanes: A Potential Application against Leishmaniasis

open access: yesMolecules, 2021
This work focuses on the search and development of drugs that may become new alternatives to the commercial drugs currently available for treatment of leishmaniasis. We have designed and synthesized 12 derivatives of bis(spiropyrazolone)cyclopropanes. We

DNA Replication Fidelity [PDF]

open access: yesAnnual Review of Biochemistry, 2000
▪ Abstract  DNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our current understanding of replication fidelity, with emphasis on structural and biochemical studies of DNA polymerases that provide new insights into the importance of hydrogen

Replicating repetitive DNA

open access: yesNature Cell Biology, 2016
The function and regulation of repetitive DNA, the 'dark matter' of the genome, is still only rudimentarily understood. Now a study investigating DNA replication of repetitive centromeric chromosome segments has started to expose a fascinating replication program that involves suppression of ATR signalling, in particular during replication stress.

MCM2-7 ring closure involves the Mcm5 C-terminus and triggers Mcm4 ATP hydrolysis

open access: yesNature Communications
The eukaryotic helicase MCM2-7, is loaded by ORC, Cdc6 and Cdt1 as a double-hexamer onto replication origins. The insertion of DNA into the helicase leads to partial MCM2-7 ring closure, while ATP hydrolysis is essential for consecutive steps in pre ...

Ctf4 organizes sister replisomes and Pol α into a replication factory

open access: yeseLife, 2019
The current view is that eukaryotic replisomes are independent. Here we show that Ctf4 tightly dimerizes CMG helicase, with an extensive interface involving Psf2, Cdc45, and Sld5. Interestingly, Ctf4 binds only one Pol α-primase.

From omics to AI—mapping the pathogenic pathways in type 2 diabetes

open access: yesFEBS Letters, EarlyView.
Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

Reconstitution of human DNA licensing and the structural and functional analysis of key intermediates

open access: yesNature Communications
Human DNA licensing initiates replication fork assembly and DNA replication. This reaction promotes the loading of the hMCM2-7 complex on DNA, which represents the core of the replicative helicase that unwinds DNA during S-phase.

Smc5/6’s multifaceted DNA binding capacities stabilize branched DNA structures

open access: yesNature Communications, 2022
Using single-molecule visualization and manipulation, Chang et al. show that the eukaryotic Smc5/6 complex preferentially binds to and stabilizes ssDNA-dsDNA junctions, which could serve as the molecular basis for its diverse roles in genome maintenance.

RAD51 interconnects between DNA replication, DNA repair and immunity

open access: yesNucleic Acids Research, 2017
RAD51, a multifunctional protein, plays a central role in DNA replication and homologous recombination repair, and is known to be involved in cancer development. We identified a novel role for RAD51 in innate immune response signaling.

DNA Replication in the Archaea [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2006
SUMMARY The archaeal DNA replication machinery bears striking similarity to that of eukaryotes and is clearly distinct from the bacterial apparatus. In recent years, considerable advances have been made in understanding the biochemistry of the archaeal replication proteins.
