Centrosome-intrinsic mechanisms modulate centrosome integrity during fever

open access: yesMolecular Biology of the Cell, 2015
The centrosome is critical for cell division, ciliogenesis, membrane trafficking, and immunological synapse function. The immunological synapse is part of the immune response, which is often accompanied by fever/heat stress (HS). Here we provide evidence that HS causes deconstruction of all centrosome substructures primarily through degradation by ...

Excessive centrosome abnormalities without ongoing numerical chromosome instability in a Burkitt's lymphoma

open access: yesMolecular Cancer, 2003
Numerical and structural centrosome abnormalities are detected in various human malignancies and have been implicated in the formation of multipolar mitoses, chromosome missegregation, and chromosomal instability.

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

open access: yesCytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Prime movers : mechanochemistry of mitotic kinesins [PDF]

open access: yes, 2014
Mitotic spindles are self-organizing protein machines that harness teams of multiple force generators to drive chromosome segregation. Kinesins are key members of these force-generating teams.

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

open access: yesCytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Cep120 is essential for kidney stromal progenitor cell growth and differentiation

open access: yesEMBO Reports, 2023
Mutations in genes that disrupt centrosome structure or function can cause congenital kidney developmental defects and lead to fibrocystic pathologies. Yet, it is unclear how defective centrosome biogenesis impacts renal progenitor cell physiology. Here,

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Dual pathway spindle assembly increases both the speed and the fidelity of mitosis [PDF]

open access: yes, 2011
Roughly half of all animal somatic cell spindles assemble by the classical prophase pathway, in which the centrosomes separate ahead of nuclear envelope breakdown (NEBD).

Seeing Invisible Oligomers: Rethinking α‐Synuclein Pathology Through Proximity Ligation Assay

open access: yesMovement Disorders, EarlyView.
Abstract Parkinson's disease (PD) and multiple system atrophy are defined by α‐synuclein (αSYN)‐positive inclusions – Lewy bodies (LBs) and glial cytoplasmic inclusions – yet mounting evidence indicates that these inclusions represent only a fraction of disease‐relevant pathology.
