The diversity of electrophysiological phenotypes of neurons in a functional network increases over development, but can be modulated, and even reduced by sensory experience; allowing them to adapt to a changing and growing brain.
Identification of importance of Angiopoietin-4 (Angpt4) as a first growth factor that initiates venous specification in the peripheral retina, and Angpt4-dependent mechanism for fluid clearance in the mouse retina.
Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.
Different developmental stages of a venomous animal (e.g. Nematostella vectensis) with a complex life cycle produce vastly different venoms that can serve in different antagonistic interactions with other species.
RNA sequencing of the African clawed frog has identified hundreds of putative direct Six1 and Eya1 target genes, including transcriptional regulators of neuronal progenitors and neuronal/sensory differentiation.
Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.
