An unbiased genetic screen in Drosophila provides evidence for a direct link between glial Ca2+ 25 signaling and classical functions of glia in buffering external K+ as a mechanism to regulate neuronal excitability.
Translational evidence indicates APOE2 benefits longevity independent of its protective effects on Alzheimer’s disease, which preserved activity and the metabolism of apoE protein and associated-lipids would be key to understanding.
A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.
Osterix, a transcription factor regulating osteoblast differentiation and bone formation, is expressed in subsets of CAFs with osteogenic features and marks tumor infiltrating immune populations enriched in immune suppressive markers.
The expression of the lipoprotein lipase (LPL) transporter GPIHBP1 in glioma capillaries promotes the LPL-mediated processing of triglyceride-rich lipoproteins, thereby providing lipid nutrients for glioma cells.
An ancient complex comprising the eukaryotic elongation factor-1A and aminoacylated tRNA is shown to be the target of a cyclic heptapeptide and two unrelated natural products with potent anticancer activity.
Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.
In the pancreas, reciprocal interactions between epithelial cells and myeloid cells determine the balance between tissue repair and carcinogenesis by regulating acinar cell plasticity through differential activation of EGFR/MAPK signaling.
The proteins Bax and Bak, which increase the permeability of the mitochondrial membrane during apoptosis, are also crucial for generating a mitochondrial membrane pore that is specifically involved in necrosis.
