Cdk1-dependent phosphorylation of Iqg1 governs actomyosin ring assembly prior to cytokinesis. [PDF]

J Cell Sci, 2014
Contraction of the actomyosin ring (AMR) provides the centripetal force that drives cytokinesis. In budding yeast, assembly and contraction of the AMR is coordinated with membrane deposition and septum formation at the bud neck. A central player in this process is Iqg1, which promotes recruitment of actin to the myosin ring and links AMR assembly with ...

Caloric restriction and aerobic exercise differentially counteract muscle–tendon dysfunction following diet‐induced obesity in C57BL/6J mice

The Journal of Physiology, EarlyView.
Abstract figure legend Diet‐induced obesity induced fibro‐adipogenic remodelling of the muscle–tendon unit, characterized by increased fibrosis, reduced specific force, impaired relaxation kinetics, elevated hysteresis, and reduced aerobic capacity and glucose tolerance.

Clinicopathological and molecular characterization of HPV‐associated cervical poorly cohesive carcinoma: a rare aggressive entity

The Journal of Pathology: Clinical Research, Volume 12, Issue 4, July 2026.
Abstract Primary signet‐ring cell carcinoma and poorly differentiated adenocarcinoma with poorly cohesive morphology in the cervix are rare conditions, and their clinicopathological features remain poorly described. This study defines primary cervical poorly differentiated adenocarcinomas meeting the diagnostic criteria for poorly cohesive carcinoma as

Astrocyte Mechanobiology: Linking Biomechanical Forces to Biochemical Signaling in the Central Nervous System

Glia, Volume 74, Issue 7, July 2026.
Astrocytes are key sensors and transducers of biomechanical stimuli within the central nervous system. Astrocyte development is highly dependent on mechanical stimuli such as surrounding tissue stiffness and biomechanical strain. Mechanosensory pathways including integrins, connexins and pannexins, and mechanosensitive channels regulate astrocyte ...

A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

eLife, 2018
To ensure timely cytokinesis, the equatorial actomyosin contractile ring constricts at a relatively constant rate despite its progressively decreasing size. Thus, the per-unit-length constriction rate increases as ring perimeter decreases.

Gene Panel Analysis Reveals Overlapping Genetic Causes of Inherited Cataracts and Other Ocular Phenotypes in Bulgarian Patients

Molecular Genetics &Genomic Medicine, Volume 14, Issue 7, July 2026.
We have identified 4 pathogenic/likely pathogenic changes and 2 variants of uncertain significance, 3 of which were novel. The identification of disease‐causing variants in the CRYAA, MYH9, RP2, and CLNC1 genes allowed us to establish an accurate genetic diagnosis of inherited cataract and to describe overlapping clinical phenotypes.

Dynamics of actin polymerisation during the mammalian single-cell wound healing response

BMC Research Notes, 2019
Objective The contribution of actomyosin contractile rings in the wound healing program of somatic cells as never been directly assessed. This contrast with the events characterising the wound healing response of in wounded Xenopus oocytes, in which ...

Phosphorylation of the F-BAR protein Hof1 drives septin ring splitting in budding yeast

Nature Communications
A double septin ring accompanies cytokinesis in yeasts and mammalian cells. In budding yeast, reorganisation of the septin collar at the bud neck into a dynamic double ring is essential for actomyosin ring constriction and cytokinesis.
