Nonlinear amplitude dynamics in flagellar beating [PDF]

Royal Society Open Science, 2017
The physical basis of flagellar and ciliary beating is a major problem in biology which is still far from completely understood. The fundamental cytoskeleton structure of cilia and flagella is the axoneme, a cylindrical array of microtubule doublets ...

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

Lissencephaly-1 is a context-dependent regulator of the human dynein complex

eLife, 2017
The cytoplasmic dynein-1 (dynein) motor plays a central role in microtubule organisation and cargo transport. These functions are spatially regulated by association of dynein and its accessory complex dynactin with dynamic microtubule plus ends. Here, we

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

Bicaudal D Family Adaptor Proteins Control the Velocity of Dynein-Based Movements

Cell Reports, 2014
Cargo transport along microtubules is driven by the collective function of microtubule plus- and minus-end-directed motors (kinesins and dyneins). How the velocity of cargo transport is driven by opposing teams of motors is still poorly understood. Here,

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

Inhibition of leucine‐rich kinase 2 (LRRK2) promotes peripheral axon regeneration via phosphorylation‐network remodelling

British Journal of Pharmacology, EarlyView.
Background and Purpose In contrast to neurons in the central nervous system, neurons in the peripheral nervous system can regenerate axons after injury via activation of a pro‐regenerative transcriptional programme. Pathogenic mutations in leucine‐rich repeat kinase 2 (LRRK2) are the most common genetic cause of Parkinson's disease, and several small ...

Registry alteration in Dynein's microtubule-binding domain: A AAA domain-guided event

Chemical Physics Impact
Dynein, a motor protein, harnesses chemical energy from ATP hydrolysis to generate mechanical output as it travels along microtubular tracks. Essential to this process is the microtubule-binding domain (MTBD), which facilitates the interaction with and ...
