Centrosome organization and functions
The centrosome, discovered near 1875, was named by Boveri when proposing the chromosomal theory of heredity. After a long eclipse, a considerable amount of molecular data has been accumulated on the centrosome and its biogenesis in the last 30 years, summarized regularly in excellent reviews.

Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene
Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.

An updated view on the centrosome as a cell cycle regulator
The centrosome is a multifunctional organelle that is known primarily for its microtubule organising function. Centrosomal defects caused by changes in centrosomal structure or number have been associated with human diseases ranging from congenital ...

This study demonstrated that ATG4B translocates from the cytoplasm to the nucleus during energy deficiency. Nuclear ATG4B inhibits DNA repair by interacting with PRMT1. The nuclear ATG4B‐mediated DNA repair defect is significantly exacerbated within acute myeloid leukemia (AML) cells, promoting leukemia progression in an AML mouse model.

Loss of E-cadherin provides tolerance to centrosome amplification in epithelial cancer cells
Centrosome amplification is a common feature of human tumors. To survive, cancer cells cluster extra centrosomes during mitosis, avoiding the detrimental effects of multipolar divisions. However, it is unclear whether clustering requires adaptation or is

Taking Down the Primary Cilium: Pathways for Disassembly in Differentiating Cells
Primary cilia are developmentally essential subcellular signaling compartments. However, many differentiated cells lack primary cilia, and cilia disassembly in these tissue contexts has been largely overlooked. We highlight several pathways for primary cilia loss and examine how changes in ciliation states could contribute to diverse pathologies ...

Ecm29-Dependent Proteasome Localization Regulates Cytoskeleton Remodeling at the Immune Synapse
The formation of an immune synapse (IS) enables B cells to capture membrane-tethered antigens, where cortical actin cytoskeleton remodeling regulates cell spreading and depletion of F-actin at the centrosome promotes the recruitment of lysosomes to ...

Three-dimensional structure of basal body triplet revealed by electron cryo-tomography. [PDF]
Basal bodies and centrioles play central roles in microtubule (MT)-organizing centres within many eukaryotes. They share a barrel-shaped cylindrical structure composed of nine MT triplet blades.

Journey to the Center of the Centrosome [PDF]
Little is understood about how the centrosome, a complex organelle and signaling hub consisting of hundreds of components, is assembled. In this issue of Developmental Cell, Conduit et al. (2014) shed light on this issue, showing that modification and recruitment of Centrosomin to the centrosome center creates a dynamic pericentriolar matrix.

When the Clock Is Ticking: The Role of Mitotic Duration in Cell Fate Determination
Recently, several studies identified mechanisms by which cells measure mitotic duration and how this influences cell fate, leading to normal cell cycle progression or G1 arrest. In light of drug‐resistant cancer cells that continue proliferating even after mitotic errors, understanding these mechanisms opens the door for new potential therapeutic ...
