A simple active fluid model unites cytokinesis, cell crawling, and axonal outgrowth

Frontiers in Cell and Developmental Biology
While the structural organization and molecular biology of neurons are well characterized, the physical process of axonal elongation remains elusive. The classic view posited elongation occurs through the deposition of cytoskeletal elements in the growth

Plant–Plant Competition Limits Arabidopsis Shoot Branching and Silique Production Independently of Soil Mineral Nutrients, Strigolactones and BRANCHED1

Plant, Cell &Environment, EarlyView.
ABSTRACT In natural environments, plants compete with neighbouring plants for resources such as light, water and nutrients. To detect neighbours, plants have evolved mechanisms that are poorly understood at the molecular‐genetic level. This study examined the impact of competition on the growth and reproductive success of Arabidopsis thaliana grown in ...

PLK4 is a potential therapeutic target in nonmelanoma skin cancers: Evidence from molecular and in vivo studies

Photochemistry and Photobiology, EarlyView.
Exposure to solar ultraviolet radiation is the main etiologic driver of nonmelanoma skin cancers (NMSCs), including basal cell (BCC) and cutaneous squamous cell carcinomas (cSCC), which are the most prevalent types of cancers in the US. In this study, we demonstrate that the serine/threonine kinase Polo‐like kinase 4 (PLK4) is overexpressed in NMSCs ...

The Myosin-V Myo51 and Alpha-Actinin Ain1p Cooperate during Contractile Ring Assembly and Disassembly in Fission Yeast Cytokinesis

Journal of Fungi
Cytokinesis is driven in part by the constriction of a ring of actin filaments, myosin motors and other proteins. In fission yeast, three myosins contribute to cytokinesis including a Myosin-V Myo51.

Deficient Cardiolipin Remodelling Alters Muscle Fibre Composition and Neuromuscular Connectivity in Barth Syndrome

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Barth syndrome (BTHS) is a rare X‐linked mitochondrial disorder caused by mutations in the TAFAZZIN gene, which disrupts cardiolipin (CL) remodelling and mitochondrial function. While cardiac manifestations of BTHS are well characterized in male patients, the mechanisms underlying skeletal muscle weakness and fatigability are poorly

Central Role of the Actomyosin Ring in Coordinating Cytokinesis Steps in Budding Yeast

Journal of Fungi
Eukaryotic cells must accurately transfer their genetic material and cellular components to their daughter cells. Initially, cells duplicate their chromosomes and subsequently segregate them toward the poles.

Survivin and Aurora Kinase A control cell fate decisions during mitosis

Molecular Oncology, Volume 20, Issue 3, Page 727-752, March 2026.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Femtosecond‐Laser‐Fabricated 3D CYTOP Microfluidic Chips Enabling Super‐Resolution Live Imaging of Cell Behavior in Confined Microspaces

Advanced Materials Technologies, Volume 11, Issue 6, 18 March 2026.
Using two‐photon polymerization of SU‐8 together with mold processing allowed the creation of defect‐free, flexible 3D microfluidic structures with sub‐micrometer precision in CYTOP. The fabricated CYTOP microfluidic chips enabled super‐resolution imaging of cancer cells in the microchannels, clearly visualizing previously undetectable fine structural ...

TOPK Inhibition Promotes Anti‐Tumor Immunity Via eIF4F Complex Mediated STAT1 Translation in Gastric Cancer

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study identifies TOPK as a dual‐function target in gastric cancer: it drives tumor cell proliferation and migration, and under IFN‐γ stimulation, phosphorylates eIF4F complex component eIF4A1 to enhance STAT1 mRNA translation, thereby promoting PD‐L1/IDO1‐mediated tumor immunometabolic evasion.

Processes Controlling the Contractile Ring during Cytokinesis in Fission Yeast, Including the Role of ESCRT Proteins

Journal of Fungi
Cytokinesis, as the last stage of the cell division cycle, is a tightly controlled process amongst all eukaryotes, with defective division leading to severe cellular consequences and implicated in serious human diseases and conditions such as cancer ...
