Methyl 4‐O‐Demethylbarbatate Destabilises HIF‐1α and Enhances Temozolomide Sensitivity in Glioma Cells

Cell Proliferation, EarlyView.
The lichen‐derived metabolite methyl 4‐O‐demethylbarbatate (Me‐4‐O‐DBA) suppresses glioma stemness, motility, and metabolic plasticity through inhibition of HIF‐1α signaling and synergistically enhances temozolomide activity, highlighting a potential strategy to target stemness‐driven therapeutic resistance in glioma.

Genomic instability leads to mutations, cellular dysfunction and aberrant phenotypes at the tissue and organism levels. A number of mechanisms have evolved to cope with endogenous or exogenous stress to prevent chromosomal instability and maintain ...

Repositioning Non‐Ablative Fractional Lasers ‐ Molecular and Histological Insights from a scoping review

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Near‐infrared non‐ablative fractional lasers (NAFL) are established for skin rejuvenation and scar treatment and have attracted interest for their expanding therapeutic potential. This scoping review aims to revisit and reposition NAFL within a fluence‐dependent continuum of tissue modulation, based on evidence from 27 studies of lasers ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

The FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not
