Cover Image
Cover: GFP-tagged PRL-expressing MDCK cells (green) were stained with anti-cleaved caspase-3 antibody (red) and DAPI (blue), and observed under confocal microscope. PRL-expression induces density-dependent apoptosis in MDCK cell culture upon confluence. The kaleidoscope-like image was made using nine of the same images. See article by S. Lohani et al. (jcs258550).

REVIEW
Centrosome maturation – in tune with the cell cycle
Summary: An overview of centrosome 3D organization, describing molecular asymmetries between the mother (mature) and the daughter (immature) centrioles, and how these are acquired in synchrony with the cell cycle.
RESEARCH ARTICLES
Integrin α6β4 requires plectin and vimentin for adhesion complex distribution and invasive growth
Summary: Integrin α6β4 is recruited with vimentin to perinuclear focal and fibrillar adhesions indicating how integrin α6β4 cooperates with other integrins to drive migration and invasive growth.
High-content image analysis to study phenotypic heterogeneity in endothelial cell monolayers
Summary: Endothelial cells heterogeneity is key to complex collective functions and cell behaviour. We developed a novel image-based endothelial cell profiling tool and quantified heterogeneity in NOTCH signalling in monolayers.
The histone H4 lysine 20 demethylase DPY-21 regulates the dynamics of condensin DC binding
Highlighted Article: The histone demethylase DPY-21 has catalytic and non-catalytic roles in condensin DC-mediated X chromosome repression. The non-catalytic activity regulates dynamics of condensin DC binding to X chromosomes.
A novel role for PRL in regulating epithelial cell density by inducing apoptosis at confluence
Summary: The oncoprotein PRL regulates epithelial cell density by driving apoptosis at confluence, which is important for convergent extension during early development in vertebrate embryos.
Multiple regions within junctin drive its interaction with calsequestrin-1 and its localization to triads in skeletal muscle
Summary: We describe the molecular interactions of the junctin luminal tail with the macromolecular complex that regulates Ca2+ release from the sarcoplasmic reticulum in skeletal muscle.
Contribution of protein–protein interactions to the endothelial-barrier-stabilizing function of KRIT1
Highlighted Article: Contrary to current models, KRIT1 does not require binding to ICAP1α and Rap1, or junctional localization, to stabilize the endothelial barrier. Instead, self-interaction and/or β1 integrin activation are critical elements of KRIT1 signaling.
Isoform-dependent lysosomal degradation and internalization of apolipoprotein E requires autophagy proteins
Summary: Alzheimer's disease-associated isoform APOE4 accumulates in lysosomes and dysregulates autophagic flux. APOE can enter the lysosome through autophagy requiring LAMP2A, a receptor for chaperone-mediated autophagy.
Chiffon triggers global histone H3 acetylation and expression of developmental genes in Drosophila embryos
Summary: Chiffon within the Gcn5-containing CHAT complex plays key roles in embryonic gene expression and histone H3 acetylation in Drosophila.
SAF-A promotes origin licensing and replication fork progression to ensure robust DNA replication
Highlighted Article: SAF-A contributes to the formation of open chromatin structure. We have discovered that SAF-A supports DNA replication at multiple steps.
The APC/C targets the Cep152–Cep63 complex at the centrosome to regulate mitotic spindle assembly
Highlighted Article: The ubiquitin ligase APC/C is required for anaphase execution and localizes to the centrosome during mitosis. Its function is to remove Cep152, an inhibitor of microtubule nucleation, from the centrosome.
CPVT-associated calmodulin variants N53I and A102V dysregulate Ca2+ signalling via different mechanisms
Summary: CaM mutations associated with human cardiac arrhythmia syndromes result in CaM dysfunction, which appears to be a key driver of the disease, with different mutants acting via different mechanisms.
Cyclophilin A regulates the apoptosis of A549 cells by stabilizing Twist1 protein
Summary: Expression, mutagenic and cytological analyses identify cyclophilin A as an important regulator of Twist1 phosphorylation and stability that acts as an inhibitor of A549 cell apoptosis.
MITOL-mediated DRP1 ubiquitylation and degradation promotes mitochondrial hyperfusion in a CMT2A-linked MFN2 mutant
Summary: Mitochondrial hyperfusion caused by the CMT2A-linked R364W mutation of MFN2 is the result of altered interactions between R364W-MFN2 and MITOL, which lead to enhanced proteasomal degradation of DRP1.

Call for papers - Cilia and Flagella: from Basic Biology to Disease

We are welcoming submissions for our upcoming special issue: Cilia and Flagella: from Basic Biology to Disease. This issue will be coordinated by two Guest Editors: Pleasantine Mill (University of Edinburgh) and Lotte Pedersen (University of Copenhagen). Extended submission deadline: 31 March 2025.
History of our journals

As our publisher, The Company of Biologists, turns 100 years old, read about Journal of Cell Science’s journey and explore the history of each of our sister journals: Development, Journal of Experimental Biology, Disease Models & Mechanisms and Biology Open.
Introducing our new Associate Editors

In this Editorial, JCS Editor-in-Chief Michael Way welcomes five new Associate Editors to the JCS team. These Associate Editors will expand our support for the wider cell biology community and handle articles in immune cell biology, proteostasis, imaging and image analysis, plant cell biology, and stem cell biology and modelling.
Diversity of microtubule arrays in animal cells at a glance

In this Cell Science at a Glance article, Emma van Grinsven and Anna Akhmanova provide an overview of the diverse microtubule arrays present in differentiated animal cells and discuss how these arrays form and function.
