PIP4K2A regulates intracellular cholesterol transport through modulating PI(4,5)P2 homeostasis

Journal of Lipid Research, 2018
The transport of LDL-derived cholesterol from lysosomes to peroxisomes is facilitated by membrane contacts formed between the lysosomal protein synaptotagmin VII and the peroxisomal lipid phosphatidylinositol 4, 5-bisphosphate [PI(4,5)P2].

Quantitative super-resolution microscopy reveals the differences in the nanoscale distribution of nuclear phosphatidylinositol 4,5-bisphosphate in human healthy skin and skin warts

Frontiers in Cell and Developmental Biology, 2023
Introduction: Imaging of human clinical formalin-fixed paraffin-embedded (FFPE) tissue sections provides insights into healthy and diseased states and therefore represents a valuable resource for basic research, as well as for diagnostic and clinical ...

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

Phosphatidylinositol4-phosphate 5-kinase prevents the decrease in the HERG potassium current induced by Gq protein-coupled receptor stimulation

Journal of Pharmacological Sciences, 2015
The human ether-a-go-go-related gene (HERG) potassium current (IHERG) has been shown to decrease in amplitude following stimulation with Gq protein-coupled receptors (GqRs), such as α1-adrenergic and M1-muscarinic receptors (α1R and M1R, respectively ...

CD47 promotes myeloma cell growth through JAK–STAT3/MYC signalling and is targetable by ruxolitinib

British Journal of Haematology, EarlyView.
Summary Cluster of differentiation 47 (CD47), a ‘don't eat me’ immune checkpoint receptor, is frequently overexpressed on multiple myeloma (MM) cells and contributes to immune evasion. While its immune regulatory function is well established, the intrinsic oncogenic role of CD47 remains poorly understood.

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

British Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Kv12.1 channels are not sensitive to GqPCR-triggered activation of phospholipase Cβ

Channels, 2018
Kv12.1 K+ channels are expressed in several brain areas, but no physiological function could be attributed to these subunits so far. As genetically-modified animal models are not available, identification of native Kv12.1 currents must rely on ...

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

A Computational Model for the Electrostatic Sequestration of PI(4,5)P2 by Membrane-Adsorbed Basic Peptides [PDF]

, 2004
The multivalent acidic phospholipid phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) plays a key role in many biological processes. Recent studies show that unstructured clusters of basic residues from a number of peripheral proteins can laterally ...

A New Case of Lethal Congenital Contracture Syndrome Type 3 With Hyperinsulinism and Optic Atrophy

Clinical Genetics, EarlyView.
PIP5K1C‐related lethal congenital contracture syndrome with hyperinsulinism and optic atrophy. ABSTRACT Lethal congenital contracture syndrome 3 (LCCS3, MIM #611369) is a rare autosomal recessive neuromuscular disorder caused by biallelic loss‐of‐function (LOF) variants in PIP5K1C, reported in only two families to date.
