Diffusion-MRI-based cerebral cortical microstructure encoding regionally differential dendritic arborization and synaptic formation at birth robustly predicts future 2-year-old cognitive and language outcomes with regionally heterogeneous contribution that exhibits functional selectivity.
A muscle-derived signaling molecule suppresses excessive accumulation of lipids in the Drosophila adipose tissue by activating the Pi3K/Akt/mTOR signaling cascade in the Drosophila hepatocyte-like cells.
Hypersensitivity of cohesin-deficient cells to Wnt signaling is concomitant with beta catenin stabilization and offers promise that Wnt agonists could be therapeutically effective in cohesin mutant cancers.
In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.
Amino acid limitation triggers preferential uncharging of glutamine-specific tRNAs and depletes polyglutamine tract-containing proteins from mammalian cells, revealing a potential role for polyglutamine tracts as sensors of glutamine sufficiency.
