Maize Thymidine Kinase Activity Is Present throughout Plant Development and Its Heterologous Expression Confers Tolerance to an Organellar DNA-Damaging Agent

open access: yesPlants, 2020
Thymidine kinase 1 (TK1) phosphorylates thymidine nucleosides to generate thymidine monophosphate. This reaction belongs to the pyrimidine salvage route that is phylogenetically conserved.

Thymidine kinase 2 (H126N) knockin mice show the essential role of balanced deoxynucleotide pools for mitochondrial DNA maintenance.

open access: yesHuman Molecular Genetics, 2008
Mitochondrial DNA (mtDNA) depletion syndrome (MDS), an autosomal recessive condition, is characterized by variable organ involvement with decreased mtDNA copy number and activities of respiratory chain enzymes in affected tissues.

The protease ADAMTS5 controls ovarian cancer cell invasion, downstream of Rab25

open access: yesThe FEBS Journal, EarlyView.
Metastatic progression is characterised by extensive remodelling of the extracellular matrix, primarily mediated by secreted proteases, including ADAMTS family members. Rainero and colleagues found that the small GTPase Rab25 promoted the expression of ADAMTS5 in ovarian cancer cells through the activation of the NF‐κB signalling pathway.

Bioavailability and cytosolic kinases modulate response to deoxynucleoside therapy in TK2 deficiencyResearch in context

open access: yesEBioMedicine, 2019
Background: TK2 is a nuclear gene encoding the mitochondrial matrix protein thymidine kinase 2 (TK2), a critical enzyme in the mitochondrial nucleotide salvage pathway.

Epidermal proteomics demonstrates Elafin as a psoriasis‐specific biomarker and highlights increased anti‐inflammatory activity around psoriatic plaques

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Epidermal sampling of lesional, perilesional and non‐lesional skin from psoriasis and eczema patients as well as healthy skin was used to perform an in depth proteomic analysis. IL‐36γ known to be expressed in lesional psoriasis skin was outperformed by the protease inhibitor Elafin as a disease‐specific epidermal biomarker.

Bi-allelic Homology-Directed Repair with Helper-Dependent Adenoviruses

open access: yesMolecular Therapy: Methods & Clinical Development, 2019
We describe a strategy to achieve footprintless bi-allelic homology-directed repair (HDR) using helper-dependent adenoviruses (HDAds). This approach utilizes two HDAds to deliver the donor DNA.

Single‐cell genomics meets systems neuroscience: Insights from mapping the brain circuitry of stress

open access: yesJournal of Neuroendocrinology, Volume 37, Issue 5, May 2025.
Abstract Responses to external and internal dangers is essential for survival and homeostatic regulation. Hypothalamic corticotropin‐releasing hormone neurons (CRHNs) play a pivotal role in regulating neuroendocrine responses to fear and stress.

Harnessing promoter elements to enhance gene editing in plants: perspectives and advances

open access: yesPlant Biotechnology Journal, Volume 23, Issue 5, Page 1375-1395, May 2025.
Summary Genome‐edited plants, endowed with climate‐smart traits, have been promoted as tools for strengthening resilience against climate change. Successful plant gene editing (GE) requires precise regulation of the GE machinery, a process controlled by the promoters, which drives its transcription through interactions with transcription factors (TFs ...
