Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Protocol for high-throughput screening of SIRT7 inhibitors using fluorescent peptide technology

STAR Protocols
Summary: Fluorescent peptides combine the polypeptides with fluorescent groups organically to facilitate the measurement of enzyme activity. Here, we present a protocol to evaluate Sirtuin 7 (SIRT7) enzymatic activity by analyzing changes in luminescent ...

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

H1N76/77 deamidation facilitates chromatin remodelling and genome stability during DNA damage repair

Clinical and Translational Medicine
Chromatin relaxation is a permissiven progress for DNA repair through enabling repair factors to access the damaged DNA. Linker histone H1 is important in maintaining chromatin compaction under physiological state.

A Chemical Screen Identifies Compounds Capable of Selecting for Haploidy in Mammalian Cells

Cell Reports, 2019
Summary: The recent availability of somatic haploid cell lines has provided a unique tool for genetic studies in mammals. However, the percentage of haploid cells rapidly decreases in these cell lines, which we recently showed is due to their overgrowth ...

Genome Instability [PDF]

Cell, 2013
To whet your appetite for the special focus in next issue’s Leading Edge on Genomic Instability, we take a look at what’s new in the field of DNA repair. Ranging from network analyses of the proteins involved in mutagenic DNA repair to examination of single molecules taking part in homologous recombination, this Select probes the inner workings of a ...

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Molecular cancer prevention: Intercepting disease

Molecular Oncology, EarlyView.
Oncological practice must evolve, from treating established tumours to proactive cancer interception before clinical manifestation. This will require mechanistic insight into tumour initiation, validated biomarkers of early disease development and redesigned clinical trials, enabling cancer interception to become a core pillar of oncology with the ...
