Voltage sensitive phosphatases: emerging kinship to protein tyrosine phosphatases from structure-function research

open access: yesFrontiers in Pharmacology, 2015
The transmembrane protein Ci-VSP from the ascidian Ciona intestinalis was described as first member of a fascinating family of enzymes, the voltage sensitive phosphatases (VSPs). Ci-VSP and its voltage-activated homologs from other species are stimulated

A Microbiota‐ and IL‐15‐Dependent Innate‐Like B Cell Progenitor Expressing E4BP4

open access: yesAdvanced Science, EarlyView.
This work identifies CD3.NKp46.CD19.NK1.1. NK‐B cells enriched in PDK1‐deficient yet present in wild‐type bone marrow. IL‐15 (via CD122) and TLR9‐microbiota signaling maintain their E4BP4 expression. These cells demonstrate innate immunity, preferentially differentiate into B cells, and unveil a novel microbiota‐ and IL‐15‐dependent regulatory pathway ...

Lysophospholipid acyltransferases and leukotriene biosynthesis: intersection of the Lands cycle and the arachidonate PI cycle[S]

open access: yesJournal of Lipid Research, 2019
Leukotrienes (LTs) are autacoids derived from the precursor arachidonic acid (AA) via the action of five-lipoxygenase (5-LO). When inflammatory cells are activated, 5-LO translocates to the nuclear membrane to initiate oxygenation of AA released by ...

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

open access: yesAdvanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Genome‐Wide CRISPR Screen Reveals PIK3CA Inhibition Enhances Lipid Nanoparticle‐Mediated siRNA Delivery

open access: yesAdvanced Science, EarlyView.
A genome‐wide CRISPR screen and identifies PIK3CA as a key regulator of lipid nanoparticle (LNP) uptake is performed. Modulating PIK3CA with small‐molecule inhibitor BAY1082439 enhanced LNP uptake, siRNA delivery, and gene silencing in a variety of epithelial cells, and improved therapeutic outcomes in vivo.

Liposome Flotation Assays for Phosphoinositide-protein Interaction

open access: yesBio-Protocol, 2017
Phosphoinositides are rare membrane lipids involved in the control of the major cellular functions and signaling pathways. They are able to recruit specific effector proteins to the cytosolic face of plasma membrane and organelles to coordinate a vast ...

Phosphoinositide phosphatases and disease

open access: yesJournal of Lipid Research, 2009
The field of inositol signaling has expanded greatly in recent years. Given the many reviews on phosphoinositide kinases, we have chosen to restrict our discussion to inositol lipid hydrolysis focused on the phosphatases and a brief mention of the lipase isoforms.
