In vivo imaging of cellular proliferation in colorectal cancer using positron emission tomography [PDF]

, 2003
Background and aims: Positron emission tomography (PET) using 18F labelled 2-fluoro-2-deoxy-D-glucose (18FDG) is an established imaging tool, although the recent development of a biologically stable thymidine analogue [18F] 3'-deoxy-3-fluorothymidine ...

Development of a genetic sensor that eliminates p53 deficient cells

Nature Communications, 2017
TP53 is mutated in many cancers, a system to detect and selectively eliminate p53 mutant cells is an attractive therapeutic strategy. Here, the authors present a genetic sensor that can detect p53 activity and is coupled to the thymidine kinase gene ...

Boron‐10 carriers and their applications in boron neutron capture therapy

Precision Radiation Oncology, EarlyView.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

Failure of dideoxynucleosides to inhibit human immunodeficiency virus replication in cultured human macrophages. [PDF]

, 1987
Primary human monocyte-derived macrophages (MDM) were shown to have diminished deoxynucleoside kinase activities compared to T lymphoblasts, and a reduced ability to phosphorylate dideoxynucleosides with anti-human immunodeficiency virus (HIV) activity ...

Dynamic Switchable and Transient DNA Condensates Driven by Aptamer‐Ligand or Ion‐Nucleobase Bridged Complexes

Small, EarlyView.
Switchable or transient formation and dissociation of the phase‐separated DNA microdroplets generated by metal ions or aptamer‐ligand complexes crosslinking Y‐shaped DNA frameworks and dynamically separated by counter ligands eliminating the bridging metal ions or biocatalysts degrading the aptamer‐ligand complexes, are introduced.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

Integrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Epidermal growth factor-mediated T-cell factor/lymphoid enhancer factor transcriptional activity is essential but not sufficient for cell cycle progression in nontransformed mammary epithelial cells [PDF]

, 2004
Because beta-catenin target genes such as cyclin D1 are involved in cell cycle progression, we examined whether beta-catenin has a more pervasive role in normal cell proliferation, even upon stimulation by non-Wnt ligands.

Down regulation by a low-zinc diet in gene expression of rat prostatic thymidylate synthase and thymidine kinase

Nutrition & Metabolism, 2008
Background Zinc has a wide spectrum of biological activities and its deficiency is related to various abnormalities of cell metabolism. Methods Wistar male rats, at age of 4 weeks, were fed a low-zinc diet for six weeks.

Dimerization‐dependent NOTCH receptor transactivation unveils a class of highly selective NOTCH signalling inhibitors

The FEBS Journal, EarlyView.
NOTCH signalling is indispensable for tissue homeostasis and, consequently, corruption of its normal function promotes numerous diseases, including cancer. However, the development of targeted therapies has been hampered by inefficacy and overt toxicity. Here, we show that NOTCH receptor dimerization is necessary for receptor transactivation, which has

Trypanosoma brucei methylthioadenosine phosphorylase protects the parasite from the antitrypanosomal effect of deoxyadenosine [PDF]

, 2016
Trypanosoma brucei causes African sleeping sickness for which no vaccine exists and available treatments are of limited use due to their high toxicity or lack of efficacy. T.
