Abstract:
An important feature of fertilization is the asymmetric inheritance of centrioles. In most species it is the sperm that contributes the initial centriole, which builds the first centrosome that is essential for early development. However, given that centrioles are thought to be exceptionally stable structures, the mechanism behind centriole disappearance in the female germ line remains elusive and paradoxical. We elucidated a program for centriole maintenance in fruit flies, led by Polo kinase and the pericentriolar matrix (PCM): The PCM is down-regulated in the female germ line during oogenes

Abstract:
Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live in starfish oocytes. Using specific fluorescent markers, we demonstrate that the two older, mother centrioles are selectively removed from the oocyte by extrusion into polar bodies. We show that this requires specific positioning of the second meiotic spindle, achieved by dynein-driven transport, and anchorage of the mother centriole to the p

Abstract:
Centrioles are remarkably stable organelles that play a main role in the assembly of centrosomes and ciliary structures. However, there are several differentiated tissues that must eliminate their centrioles to avoid centrosome formation and improper cell proliferation. Therefore, centriole elimination represents an important process in many organisms to ensure successful cell differentiation and maintenance of tissue homeostasis. In this review, we analyzed centriole inactivation and elimination in various Drosophila cell types in relation to the dynamics of the pericentriolar material.

Abstract:
Male meiosis in Trichosia pubescens (Sciaridae) was investigated by means of serial section electron microscopy and immunofluorescence light microscopy. From earlier studies of another sciarid fly, Sciara coprophila (Phillips (1967) J. Cell. Biol. 33, 73–92), it is known that the spindle poles in sciarid spermatogonia are characterized by pairs of ‘giant centrioles’, ring-shaped organelles composed of large numbers of singlet microtubules. In the present study spermatocytes in early prophase of Trichosia were found to possess single giant centrioles at opposite sides of the nucleus. The obviou

ABSTRACTSteroidogenic factor 1 (SF-1 or NR5A1) is a nuclear receptor that controls adrenogenital cell growth and differentiation. Adrenogenital primordial cells fromSF-1knockout mice die of apoptosis, but the mechanism by which SF-1 regulates cell survival is not entirely clear. Besides functioning in the nucleus, SF-1 also resides in the centrosome and controls centrosome homeostasis. Here, we show that SF-1 restricts centrosome overduplication by inhibiting aberrant activation of DNA-dependent protein kinase (DNA-PK) in the centrosome. SF-1 was found to be associated with Ku70/Ku80 only in t

Abstract Background: Increased expression of TRIM37, an E3 ligase encoded at chromosome 17q23, causes dysfunction of the pericentriolar material and creates a synthetic lethal vulnerability with PLK4 inhibition in cancer cells (Yeow, Nature 2020 and Meitinger, Nature 2020). High-risk neuroblastoma (HRNB) is a childhood cancer that is typically, widely metastatic at diagnosis and is lethal in over 50% of patients despite intensive multimodal therapy. Copy number gain of 17q is a common somatic aberration across human cancers but is a universal feature of HRNB. Here we tested the hypothesis that

Abstract PURPOSE: We aim to understand cellular and microenvironmental determinants of chromosomal instability in prostate cancer and use these findings as prognostic biomarkers portending aggressive disease. Disease transitions during prostate cancer progression are accompanied by bursts of chromosomal instability (CIN), including chromosomal translocations, oncogene amplifications, and chromothripsis. While high CIN correlates with most metrics of aggressive disease, we lack a mechanistic understanding of how CIN originates in prostate cancer. Recently, we discovered that low Gleason score,

Abstract:
In many animals, the bipolar spindle of the first zygotic division is established after the contribution of centrioles by the sperm at fertilization. To avoid the formation of a multipolar spindle in the zygote, centrosomes are eliminated during oogenesis in most organisms, although the mechanism of this selective elimination is poorly understood. We show that cki-2, a Caenorhabditis elegans cyclin-dependent kinase (Cdk) inhibitor, is required for their appropriate elimination during oogenesis. In the absence of cki-2, embryos have supernumerary centrosomes and form multipolar spindles that re

The centrosomes play an essential role in cell and tissue homeostasis, therefore, their structure, function, and number are highly regulated to ensure natural organisms development through the assembly of a multiplicity of protein complexes. Since the organization and integrity of the centrosome depend on its centrioles and pericentriolar material (PCM), understanding the dynamics of these organelles is crucial to decipher the centrosome behaviour. To date, we have a fairly detailed knowledge of the centriole composition and structure and also of the process of duplication and centrosomal matu

Abstract:
Centrosome duplication is coupled with cell division to ensure that centrosome is duplicated only once per cell cycle. This coupling, however, can be altered in specific developmental contexts although how this uncoupling occurs remains generally unclear. In C. elegans, the larval intestinal and the hypodermal cells will endocycles, while germ line stem cells eventually exit mitosis and enter meiosis. We use these models to better understand how the centrosome is intimately coupled to the cell cycle and the mechanisms though which the duplication of the centrioles can be uncoupled from cell di
