Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Three-dimensional modeling of single stranded DNA hairpins for aptamer-based biosensors

Scientific Reports, 2017
Aptamers consist of short oligonucleotides that bind specific targets. They provide advantages over antibodies, including robustness, low cost, and reusability.

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 ...

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Single-Stranded DNA Viruses in Antarctic Cryoconite Holes

Viruses, 2019
Antarctic cryoconite holes, or small melt-holes in the surfaces of glaciers, create habitable oases for isolated microbial communities with tightly linked microbial population structures. Viruses may influence the dynamics of polar microbial communities,

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

IgM AUTOANTIBODIES TO DNA IN BLOOD SERUM OF THE PATIENTS WITH HEMORRHAGIC FEVER WITH RENAL SYNDROME

Медицинская иммунология, 2014
Levels of IgM autoantibodies (AAbs) to native (double-stranded) and denaturated (single-stranded) DNA were studied in blood serum of sixty patients with hemorrhagic fever with renal syndrome (HFRS) and twenty-five healthy persons, using an ELISA ...

In situ loading and delivery of short single- And double-stranded dna by supramolecular organic frameworks [PDF]

, 2019
Short DNA represents an important class of biomacromolecules that are widely applied in gene therapy, editing, and modulation. However, the development of simple and reliable methods for their intracellular delivery remains a challenge.

Nanopore Unstacking of Single‐Stranded DNA Helices

Small, 2007
Time to unwind: The force-induced unstacking of individual single-stranded homopolymeric DNA helices is demonstrated during their translocation through an -hemolysin protein nanopore by electrophoresis (see picture). The unstacking energy and sequence-specific cooperativity are inferred from an analysis of the translocation kinetics.

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

Molecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches.
