Biochemical and biological studies reveal that caspases feed back onto the Unfolded Protein Response by cleaving the ER-stress sensor IRE1 to produce a cytoprotective N-terminal fragment that inhibits BAX-dependent apoptosis.
Post-implantation epiblast maturation and patterning of anterior-posterior axis in mouse embryonic development are mediated by pluripotency transcription factor Zfp281 through transcriptional and epigenetic control of Nodal signaling.
Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.
Lineage specification and commitment are synchronized in the developing trophectoderm lineage of the mouse embryo, but are asynchronous events in the maturing inner cell mass, revealing a window of plasticity in this lineage.
Mathematical methods based on geometry that directly embody the developmental concepts of competency, commitment, and determination provide succinct descriptions of morphogenesis and allow quantitative predictions from fits to sparse genetic data in Caenorhabditis elegans.
