Sperm dynein ATPase and ATPases associated with various cellular activities (AAA+): regulation in oligo-astheno-teratozoospermia and necrozoospermia as extreme sperm motility disorders

Journal of Biological Research, 2019
Asthenozoospermia is the most frequent sperm motility disorder, but there are other more extreme sperm motility disorders, namely oligo-astheno-teratozoospermia (OAT) and necrozoospermia.

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

Andrology, EarlyView.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

A conserved interaction of the dynein light intermediate chain with dynein-dynactin effectors necessary for processivity

Nature Communications, 2018
A growing number of cargo-specific effector proteins are being identified that interact with both dynein and dynactin and form processive dynein-dynactin-effector complexes.

Prevalence and Nationality Distribution of Known and Novel Genetic Variants in Children With Primary Ciliary Dyskinesia in the State of Qatar

Clinical Genetics, EarlyView.
CT scan image of a 17‐year‐old female with primary ciliary dyskinesia (PCD) showing dextrocardia and bilateral bronchiectasis. The study describes genetic mutations affecting patients with PCD in Qatar and the corresponding clinical phenotype of affected patients.

Interplay between kinesin-1 and cortical dynein during axonal outgrowth and microtubule organization in Drosophila neurons

eLife, 2015
In this study, we investigated how microtubule motors organize microtubules in Drosophila neurons. We showed that, during the initial stages of axon outgrowth, microtubules display mixed polarity and minus-end-out microtubules push the tip of the axon ...

Meta‐analysis of genetic mapping studies in mice reveals candidate epilepsy modifier genes that are outside the current drug development landscape

Epilepsia, EarlyView.
Abstract Objective Despite decades of development in anti‐seizure medications, ~30% of individuals remain refractory to all treatments, and none of the existing therapies are disease modifying. Identifying targets outside the current preclinical paradigm is critically important.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Mechanical Components of the Dynein Motor

The Scientific World Journal, 2010
Unlike our understanding of the other two classes of cytoskeletal motor proteins, the myosins and kinesins, we have only recently begun to comprehend the molecular mechanism for how dynein produces force and movement.

Mitochondrial control of ciliary gene expression and structure in striatal neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.
