- Lipid-associated PML structures assemble nuclear lipid droplets containing CCTα and Lipin1
PML proteins assemble into noncanonical lipid-associated PML structures (LAPS) on nuclear lipid droplets, which recruit CCTα and Lipin1 for the synthesis of phosphatidylcholine and triacylglycerol.
- RNA exosome mutations in pontocerebellar hypoplasia alter ribosome biogenesis and p53 levels
The work highlights the link between dysfunction of the RNA exosome, ribosome biogenesis, p53-dependent signalling, and apoptosis. Pontocerebellar hypoplasia caused by mutations of the exosome subunits could be classified as a ribosomopathy.
- Differential regulation of hepatic physiology and injury by the TAM receptors Axl and Mer
The TAM receptor tyrosine kinases Mer and Axl play critical roles in liver homeostasis and in the response to both acute and chronic liver injury.
- Small molecule inhibitors and a kinase-dead expressing mouse model demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cells
The study use small molecule inhibitors and a kinase-dead expressing mouse model to demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cells.
- EBV renders B cells susceptible to HIV-1 in humanized mice
A proportion of EBV+ B cells are infectible by CXCR4-tropic HIV-1 in vitro and in vivo, and these HIV-infected B cells can transmit infection to previously virus-naïve humanized mice.
- Prion infection, transmission, and cytopathology modeled in a low-biohazard human cell line
Expanding the toolbox of prion research to a low-biohazard, scalable human cell model.
- Structure of avian influenza hemagglutinin in complex with a small molecule entry inhibitor
The binding properties of fusion inhibitor CBS1117 to hemagglutinin by x-ray crystallography, NMR, and mutagenesis give insights into mechanism and guidance for chemical optimization.
- USP30 sets a trigger threshold for PINK1–PARKIN amplification of mitochondrial ubiquitylation
A new inhibitor of the deubiquitylase USP30, an actionable target relevant to Parkinson’s Disease, is introduced and characterised for parameters related to mitophagy.
- Structure of human Dispatched-1 provides insights into Hedgehog ligand biogenesis
A cryo-EM structure of human Dispatched-1 reveals a unique open conformation of its extracellular domains for Hedgehog ligand binding.
- CryoEM structure of Drosophila flight muscle thick filaments at 7 Å resolution
Relaxed thick filaments from Drosophila flight muscle show disordered myosin heads, a ribbon arrangement of myosin tails and a novel protein, stretchin-klp, on the filament surface.
