Vertebrate left-right development
Significant biological asymmetries range from the differentiation of sides within a single cell to the establishment of embryonic pattern across large fields of cells in multicellular organisms. One of the most intriguing biological asymmetries is left-right asymmetry in vertebrates. All vertebrates display a number of structures that are asymmetric along the left-right geometric body axis. The...
متن کاملA two-cilia model for vertebrate left-right axis specification.
The mechanisms underlying vertebrate left-right (L-R) axis specification have attracted much interest among developmental biologists (for review, see Burdine and Schier 2000; Capdevila et al. 2000). Of particular interest from a conceptual standpoint is the question of how L-R positional information first originates within the context of a bilaterally symmetric embryo. To achieve the consistent...
متن کاملLeft-right asymmetry in vertebrate development.
Externally the vertebrate body plan presents a bilateral symmetry in relation to the midline. However, inside the body the distribution of the visceral organs follows a very particular pattern that is not symmetrical in relation to the midline. The last 10 years have seen remarkable advances in our understanding of how the internal asymmetries typical of the vertebrate body are established and ...
متن کاملA common mechanism underlies vertebrate calcium signaling and Drosophila phototransduction.
Drosophila phototransduction is an important model system for studies of inositol lipid signaling. Light excitation in Drosophila photoreceptors depends on phospholipase C, because null mutants of this enzyme do not respond to light. Surprisingly, genetic elimination of the apparently single inositol trisphosphate receptor (InsP(3)R) of Drosophila has no effect on phototransduction. This led to...
متن کاملIntraciliary calcium oscillations initiate vertebrate left-right asymmetry
BACKGROUND Bilateral symmetry during vertebrate development is broken at the left-right organizer (LRO) by ciliary motility and the resultant directional flow of extracellular fluid. However, how ciliary motility is perceived and transduced into asymmetrical intracellular signaling at the LRO remains controversial. Previous work has indicated that sensory cilia and polycystin-2 (Pkd2), a cation...
