Polymers from dietary fiber can control the aggregation of particulates in the murine small intestine in a manner qualitatively consistent with depletion interactions.
The nutrient-sensing GCN2 signaling pathway is required for robust circadian rhythm by recruiting the histone acetyltransferase GCN5 to establish a proper chromatin state at the circadian clock gene promoter under amino acid starvation in Neurospora.
Building on previous work (Entchev et al, 2015), computational analyses reveal that the choice between redundant versus synergistic encoding in a gene expression code for food abundance is controlled by cross-talk and auto-regulation among TGF-beta and serotonin pathways.

A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.
A consistent pattern of consumption of Triticeae tribe grasses documented in the Danube Gorges of the Balkans since the Early Mesolithic might have facilitated a quick uptake of domesticated cereals due to a developed cultural taste and specific stone tool processing technology.

Structural and biochemical analysis of the mechanism of paroxetine binding to the serotonin transporter provides a framework for transporter inhibition and design of small-molecule inhibitors.
A comprehensive cross-sectional assessment reveals functional decline in mice consistent with increased energetic cost of physical activity with age through metabolic rewiring in multiple organs.

Structure–function studies on the synaptic vesicle release protein syntaxin-1 identified structural motifs on the surface of the SNARE complex controlling vesicle priming and spontaneous release unique for synaptic signaling.
