Conduction velocity of action potentials in unmyelinated axons depends ultimately on the gating variables of the fast voltage-gated sodium current and can be predicted from the action potential peak and trough voltages.
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.
Virus infection of the central nervous system disrupts the homeostasis of the immune-neural-synaptic axis via induction of pleiotropic genes with an unintended off-target negative impact on the neurotransmission.
Single-particle cryo-EM and electrophysiology studies of the chloride channel TMEM16A reveals the structural basis for anion conduction and uncover its relationship to lipid scramblases of the same family.
Infrared laser-mediated gene induction microscopy enables precise single-cell labeling in various tissues of zebrafish, and in vivo visualized single-cell lineage tracing reveals the lineage heterogeneity in hematopoietic endothelial cells.
Biochemical and genetic studies reveal a third transcription factor, BHLHE40, that together with LXR and C/EBPβ mediates insulin induction of SREBP-1c, which in turn leads to triglyceride accumulation in liver.
