FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Clustered DNA damage is related to the biological effects of ionizing radiation. However, its precise yield and complexity (i.e., number of lesions per damaged site) in vivo remain unknown. To better understand the consequences of clustered DNA damage, a

Delayed repair of radiation induced clustered DNA damage: Friend or foe?
, 2011 A signature of ionizing radiation exposure is the induction of DNA clustered damaged sites, defined as two or more lesions within one to two helical turns of DNA by passage of a single radiation track. Clustered damage is made up of double strand breaks (

FEBS Open Bio, EarlyView.KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Journal of Genetic Engineering and BiotechnologyIonizing radiation (IR) is a key cancer treatment, but its DNA-damaging effects, particularly double-strand breaks (DSBs) and clustered lesions, pose challenges for therapy.

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA
FEBS Open Bio, EarlyView.Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Analysis of Clustered DNA Damage Produced by Heavy Ion Beams
Bistranded clustered DNA damage induced by ionizing radiation is assumed to be resistant to repair and cause error prone repair, hence resulting in cell killing and mutations.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Quantitative characteristics of clustered DNA damage in irradiated cells by heavy ion beams
Heavy ion beam as typical high linear energy transfer (LET) radiation produces more expanding ionization domain around their tracks than low LET radiation such as X-rays and gamma rays.

Formation of Clustered DNA Damage after High-LET Irradiation: A Review [PDF]
, 2008 Radiation can cause as well as cure cancer. The risk of developing radiation-induced cancer has traditionally been estimated from cancer incidence among survivors of the atomic bombs in Hiroshima and Nagasaki.
