Immune signaling kinases in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD)
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Amyotrophic lateral sclerosis (ALS) is the most common neurodegenerative disorder of motor neurons in adults, with a median survival of 3–5 years after appearance of symptoms, and with no curative treatment currently ...

Histone deacetylases facilitate the accurate repair of broken forks
(Taylor & Francis, 2020)
We have recently uncovered that loss of the yeast histone deacetylases Rpd3 (Reduced Potassium Dependency 3) and Hda1 (Histone DeAcetylase 3) affects the cohesion between sister chromatids thus impairing repair of DNA ...

UAP56/DDX39B is a major cotranscriptional RNA–DNA helicase that unwinds harmful R loops genome-wide
(Cold Spring Harbor Laboratory Press, 2020)
Nonscheduled R loops represent a major source of DNA damage and replication stress. Cells have different ways to prevent R-loop accumulation. One mechanism relies on the conserved THO complex in association with cotranscriptional ...

Harmful DNA:RNA hybrids are formed in cis and in a Rad51-independent manner
(eLife Sciences Publications, 2020)
DNA:RNA hybrids constitute a well-known source of recombinogenic DNA damage. The current literature is in agreement with DNA:RNA hybrids being produced co-transcriptionally by the invasion of the nascent RNA molecule ...

Topoisomerase 1-dependent R-loop deficiency drives accelerated replication and genomic instability
(Elsevier, 2022)
DNA replication is a complex process tightly regulated to ensure faithful genome duplication, and its perturbation leads to DNA damage and genomic instability. Replication stress is commonly associated with slow and stalled ...

White Button Mushroom Extracts Modulate Hepatic Fibrosis Progression, Inflammation, and Oxidative Stress In Vitro and in LDLR-/- Mice
(MDPI, 2021)
Liver fibrosis can be caused by non-alcoholic steatohepatitis (NASH), among other conditions. We performed a study to analyze the effects of a nontoxic, water-soluble extract of the edible mushroom Agaricus bisporus (AB) ...

TDP2 suppresses genomic instability induced by androgens in the epithelial cells of prostate glands
(Wiley-Blackwell, 2020)
Androgens stimulate the proliferation of epithelial cells in the prostate by activating topoisomerase 2 (TOP2) and regulating the transcription of target genes. TOP2 resolves the entanglement of genomic DNA by transiently ...

PHF2 regulates homology-directed DNA repair by controlling the resection of DNA double strand breaks
(Oxford University Press, 2020)
Post-translational histone modifications and chromatin remodelling play a critical role controlling the integrity of the genome. Here, we identify histone lysine demethylase PHF2 as a novel regulator of the DNA damage ...

Actin nucleators safeguard replication forks by limiting nascent strand degradation
(Oxford University Press, 2023)
Accurate genome replication is essential for all life and a key mechanism of disease prevention, underpinned by the ability of cells to respond to replicative stress (RS) and protect replication forks. These responses rely ...

Spontaneous DNA-RNA hybrids: differential impacts throughout the cell cycle
(Taylor & Francis, 2020)
A large body of research supports that transcription plays a major role among the many sources of replicative stress contributing to genome instability. It is therefore not surprising that the DNA damage response has a ...
