Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

Molecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

A review on the impact of single-stranded library preparation on plasma cell-free diversity for cancer detection

Frontiers in Oncology
In clinical oncology, cell-free DNA (cfDNA) has shown immense potential in its ability to noninvasively detect cancer at various stages and monitor the progression of therapy.

In vitro synthesis of gene-length single-stranded DNA

Scientific Reports, 2018
Single-stranded DNA (ssDNA) increases the likelihood of homology directed repair with reduced cellular toxicity. However, ssDNA synthesis strategies are limited by the maximum length attainable, ranging from a few hundred nucleotides for chemical ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Binding of the Dimeric Deinococcus radiodurans Single-Stranded DNA Binding Protein to Single-Stranded DNA [PDF]

Biochemistry, 2010
Deinococcus radiodurans single-stranded (ss) DNA binding protein (DrSSB) originates from a radiation-resistant bacterium and participates in DNA recombination, replication, and repair. Although it functions as a homodimer, it contains four DNA binding domains (OB-folds) and thus is structurally similar to the Escherichia coli SSB (EcoSSB) homotetramer.

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 ...

Stitching up broken DNA ends by FANCA

Molecular & Cellular Oncology, 2018
RAD52 rejoins resected broken DNA ends by mediating single-strand annealing. Our recent work elucidates that FANCA, a Fanconi anemia protein, also directly repairs double-strand breaks (DSBs) by catalyzing annealing of single-stranded DNA.

TrmBL2 from Pyrococcus furiosus Interacts Both with Double-Stranded and Single-Stranded DNA.

PLoS ONE, 2016
In many hyperthermophilic archaea the DNA binding protein TrmBL2 or one of its homologues is abundantly expressed. TrmBL2 is thought to play a significant role in modulating the chromatin architecture in combination with the archaeal histone proteins and

Replication Protein A: Single-stranded DNA's first responder : Dynamic DNA-interactions allow Replication Protein A to direct single-strand DNA intermediates into different pathways for synthesis or repair

Bioessays, 2014
Replication protein A (RPA), the major single‐stranded DNA‐binding protein in eukaryotic cells, is required for processing of single‐stranded DNA (ssDNA) intermediates found in replication, repair, and recombination.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.
