Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

The spatial organization of sphingofungin biosynthesis in Aspergillus fumigatus and its cross-interaction with sphingolipid metabolism

open access: yesmBio
Sphingofungins are sphinganine analog mycotoxins acting as inhibitors of serine palmitoyl transferases, enzymes responsible for the first step in the sphingolipid biosynthesis.

Solvent derived artifacts in natural products chemistry

open access: yes, 2009
Solvents play an important and critical role in natural product chemistry. They are mainly used during the extraction and purification of metabolites from a biological matrix. To a lesser extent, solvents are also used as reagents or catalysts to perform

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Aporphine Alkaloids from the Chinese Tree

open access: yesNatural Product Communications, 2007
Three new oxygenated noraporphine alkaloids were isolated from the bark of the Chinese tree Neolitsea aurata var. paraciculata. The new compounds, (+)-11-methoxynorcassythicine, (+)-11-methoxynorneolitsine, (+)-11-methoxynorboldine, were isolated along ...

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

open access: yesFEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Discovery and characterization of natural products that act as pheromones in fish

open access: yes, 2018
Fish use a diverse collection of molecules to communicate with conspecifics. Since Karlson and Luscher termed these molecules 'pheromones', chemists and biologists have joined efforts to characterize their structures and functions. In particular,
