Drosophila spermatocytes have giant centrioles that display unique properties. Both the parent centrioles maintain a distinct cartwheel and nucleate a cilium-like region that persists during the meiotic divisions and organizes a structured sperm axoneme.

Estrogens—Origin of Centrosome Defects in Human Cancer?
Estrogens are associated with a variety of diseases and play important roles in tumor development and progression. Centrosome defects are hallmarks of human cancers and contribute to ongoing chromosome missegragation and aneuploidy that manifest in ...

Experimental and Natural Induction of de novo Centriole Formation
In cycling cells, new centrioles are assembled in the vicinity of pre-existing centrioles. Although this canonical centriole duplication is a tightly regulated process in animal cells, centrioles can also form in the absence of pre-existing centrioles ...

Centrosome Formation in the Bovine Early Embryo
Centrosome formation during early development in mice and rats occurs due to the appearance of centrioles de novo. In contrast, in humans and other non-rodent mammals, centrioles are thought to be derived from spermatozoa.

Centrioles are eukaryotic subcellular structures that produce and regulate massive cytoskeleton superstructures. They form centrosomes and cilia, regulate new centriole formation, anchor cilia to the cell, and regulate cilia function. These basic centriolar functions are executed in sperm cells during their amplification from spermatogonial stem cells ...

Atypical Centrioles During Sexual Reproduction
Centrioles are conserved, self-replicating, microtubule-based 9-fold symmetric subcellular organelles that are essential for proper cell division and function.

Centrioles and Ciliary Structures during Male Gametogenesis in Hexapoda: Discovery of New Models
Centrioles are-widely conserved barrel-shaped organelles present in most organisms. They are indirectly involved in the organization of the cytoplasmic microtubules both in interphase and during the cell division by recruiting the molecules needed for ...

Centrioles are microtubule-based structures involved in cell division and ciliogenesis. Centriole formation is a highly regulated cellular process and aberrations in centriole structure, size or numbers have implications in multiple human pathologies. In this review, we propose that the proteins that control centriole length can be subdivided into two ...

The precursor of the flagellar axoneme is already present in the primary spermatocytes of Drosophila melanogaster. During spermatogenesis each primary spermatocyte shows a centriole pair that moves to the cell membrane and organizes an axoneme-based ...

Evolutionary conservation of centriole rotational asymmetry in the human centrosome
Centrioles are formed by microtubule triplets in a ninefold symmetric arrangement. In flagellated protists and animal multiciliated cells, accessory structures tethered to specific triplets render the centrioles rotationally asymmetric, a property that ...
