Symmetry Breaking in a Model for Nodal Cilia [PDF]

, 2005
Nodal cilia are very short cilia found in the embryonic node on the ventral surface of early mammalian embryos. They create a right to left fluid flow that is responsible for determining the normal asymmetry of the internal organs of the mammalian body ...

Identification and Validation of Biomarkers in Chronic Rhinosinusitis With Nasal Polyps and Study of Their Associated Mechanisms

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Axonemal structure and insect phylogeny [PDF]

Bolletino di zoologia, 1993
Abstract It is now widely accepted that sperm structure can be used to resolve problems of phylogenetic relationship. In the present study we consider one component of the spermatozoon only, namely the flagellar axoneme, and we restrict the study to insects, in particular to Diptera and Trichoptera.

Sequence and expression analysis of potential spermatogenesis‐specific gene cognates in the Caribbean fruit fly, Anastrepha suspensa

Insect Science, EarlyView.
Abstract The sterile insect technique (SIT) is a highly effective biologically‐based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness.

Sperm-associated antigen 6 (SPAG6) deficiency and defects in ciliogenesis and cilia function: polarity, density, and beat. [PDF]

PLoS ONE, 2014
SPAG6, an axoneme central apparatus protein, is essential for function of ependymal cell cilia and sperm flagella. A significant number of Spag6-deficient mice die with hydrocephalus, and surviving males are sterile because of sperm motility defects.

Intraflagellar transport delivers tubulin isotypes to sensory cilium middle and distal segments. [PDF]

, 2011
Sensory cilia are assembled and maintained by kinesin-2-dependent intraflagellar transport (IFT). We investigated whether two Caenorhabditis elegans α- and β-tubulin isotypes, identified through mutants that lack their cilium distal segments, are ...

Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]

, 1982
The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

RPGR protein complex regulates proteasome activity and mediates store-operated calcium entry [PDF]

, 2018
Ciliopathies are a group of genetically heterogeneous disorders, characterized by defects in cilia genesis or maintenance. Mutations in the RPGR gene and its interacting partners, RPGRIP1 and RPGRIP1L, cause ciliopathies, but the function of their ...

Reconstruction of native cellular microanatomy in a novel bioengineered full thickness human nasal mucosal construct

Journal of Anatomy, EarlyView.
Bioengineered tissue constructs are vital technologies employed in in vitro testing of both fundamental biological principles and industrial screening practices. Current approaches to modelling the nasal mucosa in vitro are not representative and are associated with limitations that impact their reliability and predictive value.

Resolving Trypanosoma brucei Flagellar Structure by Cryo-Electron Tomography [PDF]

E3S Web of Conferences, 2019
Trypanosoma brucei is a unicellular eukaryote that can cause human African trypanosomiasis, which has continued to evolve and spread. The key feature of these parasites is that they have a flagellum consists of a typical 9 + 2 axoneme and a lattice-like ...
