The vertebrate body plan has conserved handed left-right (LR) asymmetry that is manifested in the heart, lungs, and gut. Leftward flow of extracellular fluid at the node (nodal flow) is critical for normal LR axis determination in the mouse. Nodal flow is generated by motile node cell monocilia and requires the axonemal dynein, left-right dynein (lrd). In(More)
Heterotaxy is a disorder of left-right body patterning, or laterality, that is associated with major congenital heart disease. The aetiology and mechanisms underlying most cases of human heterotaxy are poorly understood. In vertebrates, laterality is initiated at the embryonic left-right organizer, where motile cilia generate leftward flow that is detected(More)
Motile cilia create asymmetric fluid flow in the evolutionarily conserved ciliated organ of asymmetry (COA) and play a fundamental role in establishing the left-right (LR) axis in vertebrate embryos. The transcriptional control of the large group of genes that encode proteins that contribute to ciliary structure and function remains poorly understood. In(More)
