Across species: A comparative perspective on red cell homeostasis and its influence on our understanding of human physiology and disease

British Journal of Haematology, EarlyView.
This review highlights how studies on animal red cells have enriched our understanding of the behaviour of those from humans. A comparative perspective has enhanced our knowledge of human red cell pathophysiology Summary This review emphasises how studies on animal red cells have enriched our understanding of the behaviour of those from humans.

Ion channel regulation by phosphoinositides analyzed with VSPs – PI(4,5)P2 affinity, phosphoinositide selectivity, and PI(4,5)P2 pool accessibility

Frontiers in Pharmacology, 2015
The activity of many proteins depends on the phosphoinositide (PI) content of the membrane. E.g., dynamic changes of the concentration of PI(4,5)P2 are cellular signals that regulate ion channels.

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

British Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Low Cholesterol Triggers Membrane Microdomain-dependent CD44 Shedding and Suppresses Tumor Cell Migration*

Journal of Biological Chemistry, 2010
CD44 is a cell surface adhesion molecule for hyaluronan and is implicated in tumor invasion and metastasis. Proteolytic cleavage of CD44 plays a critical role in the migration of tumor cells and is regulated by factors present in the tumor ...

Liquid–Liquid Phase Separation in Major Hallmarks of Cancer

Cell Proliferation, EarlyView.
Aberrant condensates formed through phase separation are involved in the dysregulation of various critical cellular processes, including genome stability, transcriptional regulation and signal transduction, thereby promoting malignant transformation and the acquisition of multiple cancer hallmarks.

An Overview of Biomembrane Functions in Plant Responses to High-Temperature Stress

Frontiers in Plant Science, 2018
Biological membranes are highly ordered structures consisting of mosaics of lipids and proteins. Elevated temperatures can directly and effectively change the properties of these membranes, including their fluidity and permeability, through a holistic ...

Label‐free imaging of intracellular structures in living mammalian cells via external apodization phase‐contrast microscopy

The FEBS Journal, EarlyView.
External apodization phase‐contrast (ExAPC) microscopy enables label‐free visualization of diverse intracellular structures in living mammalian cells. By enhancing phase‐contrast imaging through optical apodization, ExAPC reveals fine subcellular details, such as lipid droplets and organelle contacts, without fluorescent labels.

Direct evidence for microdomain-specific localization and remodeling of functional L-type calcium channels in rat and human atrial myocytes

, 2015
Background—Distinct subpopulations of L-type calcium channels (LTCCs) with different functional properties exist in cardiomyocytes. Disruption of cellular structure may affect LTCC in a microdomain-specific manner and contribute to the pathophysiology of

Dynamics of the CD9 interactome during bacterial infection of epithelial cells by proximity labelling proteomics

The FEBS Journal, EarlyView.
We describe the CD9 interactome in epithelial cells for the first time. The interactome is diverse and dynamic and changes dependent on infection with specific bacteria. We validate these data by showing functional interaction between CD9 with CD44 or CD147. We therefore demonstrate that CD9 is a universal organiser of bacterial adhesion platforms able

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),
