Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly
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 ...

Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development
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 ...

Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

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 ...

Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

Molecular anatomy of emerging Xenopus left–right organizer at successive developmental stages
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,

Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Abstract Due to the limited regenerative capacity in adult mammals, the loss of vestibular hair cells (HCs) leads to balance disorders. In this study, we chronologically reprogrammed adult vestibular supporting cells (SCs) via bimodal regulation of Notch signaling, mimicking dynamic changes in Notch signaling during inner ear development. We found that

Saxifraga rufescens var. rufescens (Saxifragaceae): A New Addition to the Flora of India
ABSTRACT Saxifraga rufescens Balf.f., a species of Saxifragaceae, previously known from China and Myanmar, is now recorded from Nagaland, India. This study offers detailed morphological descriptions, habitat characteristics, field photographs, distributional data, and an analysis of its taxonomic relationships with closely related species, facilitating
