Molecular mechanism of GIRK2 channel gating modulated by cholesteryl hemisuccinate

Frontiers in Physiology
Cholesterol, an essential lipid of cell membranes, regulates G protein-gated inwardly rectifying potassium (GIRK) channel activity. Previous studies have shown that cholesterol activates GIRK2 homotetrameric channels, which are expressed in dopaminergic ...

Fungal Polysaccharides as Next‐Generation Bioactive: Advances in Structure–Activity Mapping, Mode of Action, and Biotechnological Horizons

Food Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Fungal polysaccharides (FPs) represent a diverse class of bioactive macromolecules widely studied for their nutritional, therapeutic, and biotechnological value. This review synthesizes recent advances (2020–2025) in the structural characterization, biological functions, and translational potential of FPs.

Opening closed inward rectifier potassium channel doors

British Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Effect of hormone-induced plasma membrane phosphatidylinositol 4,5-bisphosphate depletion on receptor endocytosis suggests the importance of local regulation in phosphoinositide signaling

Scientific Reports
Phosphatidylinositol 4,5-bisphosphate (PIP2) has been shown to be critical for the endocytosis of G protein-coupled receptors (GPCRs). We have previously demonstrated that depletion of PIP2 by chemically induced plasma membrane (PM) recruitment of a 5 ...

Exosomal Non‐Coding RNAs in Gastrointestinal Cancer Drug Resistance: A Systematic Review of Emerging Mechanisms and Clinical Implications

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Gastrointestinal (GI) tumours are one of the most prevalent cancers globally. Even with normal GI function, individuals may develop neoplasms, highlighting the need to better understand the underlying causes of tumorigenesis. The emergence of tumour drug resistance represents the main reason for the failure of drug treatment; thus, it is ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

Journal of Anatomy, Volume 248, Issue 5, Page 784-805, May 2026.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Adipose Triglyceride Lipase and Gpr40 Contribute to the Anti‐Contractile Effect of Perivascular Adipose Tissue

Microcirculation, Volume 33, Issue 4, May 2026.
ABSTRACT Objective Perivascular adipose tissue (PVAT) surrounds most peripheral blood vessels and exerts an anti‐contractile influence through paracrine mediators. Although numerous vasoactive factors have been identified, the mechanisms linking adipocyte metabolism to PVAT‐dependent modulation of vascular tone remain poorly defined. Because adipocytes
