SAS-4 is recruited to a dynamic structure in newly forming centrioles that is stabilized by the gamma-tubulin-mediated addition of centriolar microtubules. [PDF]

, 2008
Centrioles are surrounded by pericentriolar material (PCM), which is proposed to promote new centriole assembly by concentrating gamma-tubulin. Here, we quantitatively monitor new centriole assembly in living Caenorhabditis elegans embryos, focusing on ...

Lysine demethylase 4A is a centrosome‐associated protein required for centrosome integrity and genomic stability

The FEBS Journal, Volume 293, Issue 2, Page 396-417, January 2026.
KDM4A, a chromatin eraser, localizes to the centrosomes. Its demethylase activity is essential for maintaining centrosome number and integrity, independent of gene expression changes. Loss of KDM4A leads to centrosome amplification, pseudo‐bipolar spindle formation, and chromosome segregation errors, including micronuclei and chromatin bridges.

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica

New Phytologist, Volume 249, Issue 1, Page 524-538, January 2026.
Summary Polyploidization, followed by genome downsizing, is a recurrent evolutionary cycle that dramatically reshapes genome structure. Newly formed polyploids must quickly adjust their cell division machinery to maintain stable chromosome inheritance, while long‐term stabilization involves rediploidization, returning the genome to a diploid‐like state.

siRNA-Mediated BmAurora B Depletion Impedes the Formation of Holocentric Square Spindles in Silkworm Metaphase BmN4 Cells

Insects
Silkworm ovary-derived BmN4 cells rely on chromatin-induced spindle assembly to form microtubule-based square mitotic spindles that ensure accurate segregation of holocentric chromosomes during cell division.
