Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Introducing a modified sample preparation and straightforward elemental ratio determination strategy with LA-ICP-MS to expand the nanoparticle probing toolkit

Advances in Sample Preparation
Nanoparticles (NPs) are employed in a wide range of applications due to some of their unique characteristics. Since their properties are partly determined by their composition, accurate determination of their stoichiometry is of paramount importance for ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Sorbent-less dried blood spot microsampling

Advances in Sample Preparation
Dried blood spots (DBSs) are typically sampled on porous sorbents, which may retain analytes in their structure during DBS rehydration but also release various species into the eluates and contaminate them.

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.
