Autoregulation of the real-time kinetics of the human mitochondrial replicative helicase

open access: yesNature Communications
The human mitochondrial helicase Twinkle is essential for mitochondrial DNA (mtDNA) replication and integrity. Using biochemical and single-molecule techniques, we investigated Twinkle’s real-time kinetics, including DNA loading, unwinding, and rewinding,

ruvA Mutants that resolve Holliday junctions but do not reverse replication forks

open access: yes, 2008
RuvAB and RuvABC complexes catalyze branch migration and resolution of Holliday junctions (HJs) respectively. In addition to their action in the last steps of homologous recombination, they process HJs made by replication fork reversal, a reaction which ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Telomere and ribosomal DNA repeats are chromosomal targets of the bloom syndrome DNA helicase

open access: yesBMC Cell Biology, 2003
Background Bloom syndrome is one of the most cancer-predisposing disorders and is characterized by genomic instability and a high frequency of sister chromatid exchange. The disorder is caused by loss of function of a 3' to 5' RecQ DNA helicase, BLM. The

RECQL: a DNA helicase in breast cancer

open access: yesOncotarget, 2015
We recently reported that mutations in the RECQL gene are associated with an increased risk of breast cancer [1]. We identified recurrent RECQL mutations in two founder populations in Poland and Quebec, Canada, and we found that these mutations increase the risk of breast cancer by 5-fold among unselected cases from Poland and by 16-fold among higher ...

Phosphorylation events surrounding the DNA damage response in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2007
Protein phosphorylation mediated by checkpoint kinases is crucial for the cellular response to DNA damage. The sensor kinases Mec1 and Tel1 initiate the checkpoint signaling cascade by directly activating the checkpoint effector kinase Rad53.

LPCAT3 as a Potential Drug Target for Ultraviolet Radiation–Induced Cataract: Insights From Multiomics Analysis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Ultraviolet B (UVB) radiation is a major risk factor for cataract development, but the molecular mechanisms underlying this process, particularly the involvement of regulated cell death pathways such as ferroptosis, remain unclear. Transcriptomic, proteomic, and metabolomic analyses were performed on lens tissues from UVB‐induced cataract rat ...

Cellular location and activity of Escherichia coli RecG proteins shed light on the function of its structurally unresolved C-terminus [PDF]

open access: yes, 2014
RecG is a DNA translocase encoded by most species of bacteria. The Escherichia coli protein targets branched DNA substrates and drives the unwinding and rewinding of DNA strands.

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a global health threat, with an estimated 282 million cases and 610,000 malaria‐associated deaths reported in 2024. Most mortality is due to infection by Plasmodium falciparum parasites, with the highest burden occurring in Sub‐Saharan Africa.
