CENTRIOLE REPLICATION [PDF]

open access: yesThe Journal of Cell Biology, 1966
Sperm formation was studied in the fern, Marsilea, and the cycad, Zamia, with particular emphasis on the centrioles. In Marsilea, the mature sperm possesses over 100 flagella, the basal bodies of which have the typical cylindrical structure of centrioles. Earlier observations by light microscopy suggested that these centrioles arise by fragmentation of

Deuterosome-Mediated Centriole Biogenesis [PDF]

open access: yesDevelopmental Cell, 2013
The ability of cells to faithfully duplicate their two centrioles once per cell cycle is critical for proper mitotic progression and chromosome segregation. Multiciliated cells represent an interesting variation of centriole duplication in that these cells generate greater than 100 centrioles, which form the basal bodies of their motile cilia.

Parkinson's‐Linked LRRK2 and GBA1 Mutations Modulate the Peripheral Immune Response to Pseudomonas aeruginosa

open access: yesMovement Disorders, EarlyView.
Abstract Background Peripheral disease mechanisms such as immune dysregulation may contribute to Parkinson's disease (PD). To investigate interactions between common PD mutations and immune responses to environmental pathogens, we studied responses to Pseudomonas aeruginosa (P.

Towards understanding centriole elimination

open access: yesOpen Biology, 2023
Centrioles are microtubule-based structures crucial for forming flagella, cilia and centrosomes. Through these roles, centrioles are critical notably for proper cell motility, signalling and division. Recent years have advanced significantly our understanding of the mechanisms governing centriole assembly and architecture.

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

CenFind: a deep-learning pipeline for efficient centriole detection in microscopy datasets

open access: yesBMC Bioinformatics, 2023
Background High-throughput and selective detection of organelles in immunofluorescence images is an important but demanding task in cell biology. The centriole organelle is critical for fundamental cellular processes, and its accurate detection is key ...

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

open access: yesAndrology, 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.

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

open access: yesAndrology, 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.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

PLK4 is a potential therapeutic target in nonmelanoma skin cancers: Evidence from molecular and in vivo studies

open access: yesPhotochemistry and Photobiology, EarlyView.
Exposure to solar ultraviolet radiation is the main etiologic driver of nonmelanoma skin cancers (NMSCs), including basal cell (BCC) and cutaneous squamous cell carcinomas (cSCC), which are the most prevalent types of cancers in the US. In this study, we demonstrate that the serine/threonine kinase Polo‐like kinase 4 (PLK4) is overexpressed in NMSCs ...
