Cytoskeleton, EarlyView.ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

BioArchitecture, 2012 The radial spoke (RS) is a complex of at least 23 proteins that works as a mechanochemical transducer between the central-pair apparatus and the peripheral microtubule doublets in eukaryotic flagella and motile cilia. The RS contributes to the regulation of the activity of dynein motors, and thus to flagellar motility.

Cytoplasmic factories for axonemal dynein assembly [PDF]
Journal of Cell Science, 2021 ABSTRACT Axonemal dyneins power the beating of motile cilia and flagella. These massive multimeric motor complexes are assembled in the cytoplasm, and subsequently trafficked to cilia and incorporated into the axonemal superstructure. Numerous cytoplasmic factors are required for the dynein assembly process, and, in mammals, defects lead

Molecular basis of the morphogenesis of sperm head and tail in mice
Reproductive Medicine and Biology, 2022 Background The spermatozoon has a complex molecular apparatus necessary for fertilization in its head and flagellum. Recently, numerous genes that are needed to construct the molecular apparatus of spermatozoa have been identified through the analysis of

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

Microtubule-Associated Proteins: From Dynamic Regulation of Microtubules to Cellular Architecture
CellsMicrotubule-associated proteins (MAPs) are key regulators of microtubule architecture and dynamics, orchestrating microtubule stability, post-translational modification, and spatial organization across diverse cellular contexts. Through these activities,

eLife, 2021 We propose and discuss a model for flagellar mechanics in Euglena gracilis. We show that the peculiar non-planar shapes of its beating flagellum, dubbed 'spinning lasso', arise from the mechanical interactions between two of its inner components, namely,

The Airway Transcriptome in Type 2 Cytokine Biomarker‐High and ‐Low Severe Asthma
Allergy, EarlyView.This study distinguishes severe asthma–related airway transcriptomic changes from the effects of high‐dose ICS. Most dysregulated genes in severe asthma show concordance with corticosteroid responses. Corticosteroid‐resistant T2‐high asthma featured T2‐high and epithelial barrier gene upregulation, while T2‐low asthma featured Th1/IL‐17 signatures. ASM,

Andrology, EarlyView.ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.
