Fyn-Mediated Regulation of Protein Kinase A [PDF]

, 2017
Protein kinases are enzymes important for signal transduction in the regulation of cellular processes. The cAMP-dependent protein kinase A (PKA) has been previously reported to regulate the activity of the Src family kinase Fyn, an event important for ...

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

The DNA replication machinery transmits dual signals to prevent unscheduled licensing and execution of centrosome duplication

Nature Communications
Copy number control of DNA and centrosomes is essential for accurate genetic inheritance. DNA replication and centrosome duplication have been recognized as parallel key events for cell division.

Monoclonal Antibodies Accessing the Cytosol of Living Cells and Binding to Polo‐Like Kinase 1 Interdomain Linker Affect Mitotic Behavior

ChemBioChem, Volume 27, Issue 9, 14 May 2026.
Monoclonal antibodies targeting the interdomain region of polo‐like kinase 1 (PLK1) were delivered into living HeLa cells by electroporation to directly modulate mitotic progression. This intracellular antibody approach provides a new tool to probe PLK1 function and highlights the potential of antibodies to regulate key mitotic regulators inside cells.

A Cancer-Associated Missense Mutation in PP2A-Aα Increases Centrosome Clustering during Mitosis

iScience, 2019
Summary: Whole-genome doubling (WGD) is common early in tumorigenesis. WGD doubles ploidy and centrosome number. In the ensuing mitoses, excess centrosomes form a multipolar spindle, resulting in a lethal multipolar cell division.

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, Volume 16, Issue 5, Page 821-836, May 2026.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Tetraploidy-associated centrosome overduplication in mouse early embryos

Communicative & Integrative Biology, 2018
Recently, we observed that tetraploidization of certain types of human cancer cells resulted in upregulation of centrosome duplication cycles and chronic generation of the extra centrosome. Here, we investigated whether tetraploidy-linked upregulation of

FGFR Like1 drives esophageal cancer progression via EMT, PI3K/Akt, and notch signalling: insights from clinical data and next‐generation sequencing analysis

FEBS Open Bio, Volume 16, Issue 5, Page 979-999, May 2026.
Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.

Centrosome and retroviruses: The dangerous liaisons

Retrovirology, 2007
Centrosomes are the major microtubule organizing structures in vertebrate cells. They localize in close proximity to the nucleus for the duration of interphase and play major roles in numerous cell functions.

Targeting the nuclear export receptor exportin‐1 in acute myeloid leukaemia: From biology to clinical translation

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
• XPO1 hyperactivation promotes leukaemogenesis by altering nucleocytoplasmic transport and transcriptional control in acute myeloid leukaemia (AML). • Selinexor and eltanexor show preferential activity in NPM1‐mutated, DEK::NUP214‐positive and SF3B1‐mutated myeloid neoplasms.
