DNA repair nucleases [PDF]

open access: yesCellular and Molecular Life Sciences (CMLS), 2004
Stability of DNA largely depends on accuracy of repair mechanisms, which remove structural anomalies induced by exogenous and endogenous agents or introduced by DNA metabolism, such as replication. Most repair mechanisms include nucleolytic processing of DNA, where nucleases cleave a phosphodiester bond between a deoxyribose and a phosphate residue ...

Endogenous TDP-43 mislocalization in a novel knock-in mouse model reveals DNA repair impairment, inflammation, and neuronal senescence

open access: yesActa Neuropathologica Communications
TDP-43 mislocalization and aggregation are key pathological features of amyotrophic lateral sclerosis (ALS)- and frontotemporal dementia (FTD). However, existing transgenic hTDP-43 WT or ∆NLS-overexpression animal models primarily focus on late-stage TDP-

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

RNA in DNA repair

open access: yesDNA Repair, 2020
Our genome is constantly subject to damage from exogenous and endogenous sources, and cells respond to such damage by initiating a DNA damage response (DDR). Failure to induce an adequate DDR can result in increased mutation load, chromosomal aberrations and a variety of human diseases, including cancer. A rapidly growing body of evidence suggests that

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Benchmarking multiple gene ontology enrichment tools reveals high biological significance, ranking, and stringency heterogeneity among datasets

open access: yesFrontiers in Bioinformatics
Functional enrichment analysis (FEA) provides biological meaning from lists of differentially expressed genes and proteins obtained through omics experiments. FEA tools can employ numerous statistical methods and rely on different pathway databases.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

The Journey of DNA Repair [PDF]

open access: yesTrends in Cancer, 2015
21 years ago, the DNA Repair Enzyme was declared "Molecule of the Year". Today, we are celebrating another "year of repair", with the 2015 Nobel Prize in Chemistry being awarded to Aziz Sancar, Tomas Lindahl and Paul Modrich for their collective work on the different DNA repair pathways.

Targeted protein degradation in oncology: novel therapeutic opportunity for solid tumours?

open access: yesMolecular Oncology
Targeted and immune therapies have improved patient outcomes in selected diseases. Still, resistance inevitably occurs, and a significant portion of the proteome remains undruggable due to target localisation, structural or functional constraints ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
