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

Mechanical Properties of Inner-Arm Dynein-F (Dynein I1) Studied With In Vitro Motility Assays

, 2007
Inner-arm dynein-f of Chlamydomonas flagella is a heterodimeric dynein. We performed conventional in vitro motility assays showing that dynein-f translocates microtubules at the comparatively low velocity of ∼1.2μm/s. From the dependence of velocity upon

A mouse neurodegenerative dynein heavy chain mutation alters dynein motility and localization in Neurospora crassa

, 2012
Cytoplasmic dynein is responsible for the transport and delivery of cargoes in organisms ranging from humans to fungi. Dysfunction of dynein motor machinery due to mutations in dynein or its activating complex dynactin can result in one of several ...

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.

Reconstitution of dynein transport to the microtubule plus end by kinesin

eLife, 2014
Cytoplasmic dynein powers intracellular movement of cargo toward the microtubule minus end. The first step in a variety of dynein transport events is the targeting of dynein to the dynamic microtubule plus end, but the molecular mechanism underlying this

Shared and specific molecular mechanisms of proteasome inhibitors in chemotherapy‐induced peripheral neurotoxicity

British Journal of Pharmacology, EarlyView.
This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

Roles of dynein and dynactin in early endosome dynamics revealed using automated tracking and global analysis.

PLoS ONE, 2011
Microtubule-dependent movement is crucial for the spatial organization of endosomes in most eukaryotes, but as yet there has been no systematic analysis of how a particular microtubule motor contributes to early endosome dynamics.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

Clinical Genetics, EarlyView.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

The XMAP215-family protein DdCP224 is required for cortical interactions of microtubules

BMC Cell Biology, 2004
Background Interactions of peripheral microtubule tips with the cell cortex are of crucial importance for nuclear migration, spindle orientation, centrosome positioning and directional cell movement.

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

The FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...
