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 ...

digestion procedure for Re–Os isotope analysis and its implications for organic‐rich sedimentary rocks and mafic rocks

, 2023
The precision of available Re-Os isotope analysis for organic-rich sedimentary (ORS) rocks is influenced by the coexisting clastic and organic components and the considerable differences between Re and Os mass fractions in such rocks.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Re-os isotope constraints on the age of the Lithospheric mantle beneath western Greenland. [PDF]

, 2007
Alkaline magmatic activity across Western Greenland (W.G.) provides a record of lithosphere evolution over the last 600 Ma. Ultra Mafic Lamprophyre (UML) magmatism in particular has erupted an exceptional inventory of mantle xenoliths allowing a detailed

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Re-Os geochronology and isotope systematics of the Tanami, Tennant Creek and Olympic Dam Cu-Au deposits

, 2008
The 187Re-187Os system can determine directly the age of formation of ore deposits and can characterise the isotopic provenance of metals in ore systems. We report rhenium-osmium (Re-Os) isotope data from the Callie gold deposit of the Tanami district in

Nickel and osmium isotope and trace element geochemistry of organic-rich sedimentary rocks: The first investigation of Ni isotope systematics in marine sediments [PDF]

, 2012
Understanding the chemical composition of organic-rich marine sediments has the potential to: 1) allow evaluation of variations in ocean chemistry, enabling assessment of changes in global processes throughout geological time; and 2) provide an increased
