Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly
Cytoskeleton, EarlyView.ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Modelling the Fluid Mechanics of Cilia and Flagella in Reproduction and Development [PDF]
Montenegro-Johnson et al, Eur. Phys. J. E, 35 10 (2012) 111, 2013 Cilia and flagella are actively bending slender organelles, performing functions such as motility, feeding and embryonic symmetry breaking. We review the mechanics of viscous-dominated microscale flow, including time-reversal symmetry, drag anisotropy of slender bodies, and wall effects.

A role for Gle1, a regulator of DEAD-box RNA helicases, at centrosomes and basal bodies. [PDF]
, 2017 Control of organellar assembly and function is critical to eukaryotic homeostasis and survival. Gle1 is a highly conserved regulator of RNA-dependent DEAD-box ATPase proteins, with critical roles in both mRNA export and translation.

Inactivation of Chibby affects function of motile airway cilia [PDF]
Journal of Cell Biology, 2009 Chibby (Cby) is a conserved component of the Wnt–β-catenin pathway. Cby physically interacts with β-catenin to repress its activation of transcription. To elucidate the function of Cby in vertebrates, we generated Cby−/− mice and found that after 2–3 d of weight loss, the majority of mice die before or around weaning.

Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development
Developmental Dynamics, EarlyView.Abstract Cilia are specialized structures found on a variety of mammalian cells, with variable roles in the transduction of mechanical and biological signals (by primary cilia, PC), as well as in the generation of fluid flow (by motile cilia). Their critical role in the establishment of a left–right axis in early development is well described, as well ...

Eukaryotic swimming cells are shaped by hydrodynamic constraints [PDF]
arXiv, 2023 Eukaryotic swimming cells such as spermatozoa, algae or protozoa use flagella or cilia to move in viscous fluids. The motion of their flexible appendages in the surrounding fluid induces propulsive forces that balance with the viscous drag on the cells and lead to a directed swimming motion.

Frontiers in Genetics, 2019 Developmental defects in motile cilia, arising from genetic abnormalities in one or more ciliary genes, can lead to a common ciliopathy known as primary ciliary dyskinesia (PCD). Functional studies in model organisms undertaken to understand PCD or cilia

A Complex of BBS1 and NPHP7 Is Required for Cilia Motility in Zebrafish [PDF]
PLoS ONE, 2013 Bardet-Biedl syndrome (BBS) and nephronophthisis (NPH) are hereditary autosomal recessive disorders, encoded by two families of diverse genes. BBS and NPH display several overlapping phenotypes including cystic kidney disease, retinitis pigmentosa, liver fibrosis, situs inversus and cerebellar defects. Since most of the BBS and NPH proteins localize to

Developmental Dynamics, EarlyView.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Molecular anatomy of emerging Xenopus left–right organizer at successive developmental stages
Developmental Dynamics, EarlyView.Abstract Background Vertebrate left–right symmetry breaking is preceded by formation of left–right organizer. In Amphibian, this structure is formed by gastrocoel roof plate, which emerges from superficial suprablastoporal cells. GRP is subdivided into medial area, which generates leftward flow by rotating monocilia and lateral Nodal1 expressing areas,
