Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.
A separation-of-function mutation reveals that a niche ligand receptor Dome functions in spindle orientation during asymmetric stem cell division by directly binding to Eb1, independent of its role in downstream JAK-STAT signaling.
Plasmodium parasite transcription shifts dramatically along asexual development, and transmission stages variably express important immune evasion genes, suggesting much interesting biology has until now been hidden by bulk analyses.
Structural and functional striatal synaptic plasticity abnormalities occur early in a sensitive developmental period, representing a potential unique endophenotypic traits that increase the risk of manifesting clinical symptoms in DYT1 mutation carriers.
Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.
Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.
