LPP3 mediates self-generation of chemotactic LPA gradients by melanoma cells [PDF]

, 2017
Melanoma cells steer out of tumours using self-generated lysophosphatidic acid (LPA) gradients. The cells break down LPA, which is present at high levels around the tumours, creating a dynamic gradient that is low in the tumour and high outside.

Phosphatidic Acid‐TRIM59‐Olig2 Signaling Couples Metabolic Dysfunction to Myelination Failure in PWMI

Advanced Science, Volume 13, Issue 25, 4 May 2026.
PA accumulates after hypoxic‐ischemic injury and stabilizes the E3 ligase TRIM59 in OPCs. Stabilized TRIM59 enhances ubiquitination and degradation of Olig2, blocking differentiation and causing hypomyelination in PWMI. Modulating PA synthesis restores Olig2 levels, improves myelination, and ameliorates behavioral deficits, defining a metabolically ...

LPA receptor signaling: pharmacology, physiology, and pathophysiology

Journal of Lipid Research, 2014
Lysophosphatidic acid (LPA) is a small ubiquitous lipid found in vertebrate and nonvertebrate organisms that mediates diverse biological actions and demonstrates medicinal relevance. LPA's functional roles are driven by extracellular signaling through at

FOXM1 is a downstream target of LPA and YAP oncogenic signaling pathways in high grade serous ovarian cancer [PDF]

, 2015
Lysophosphatidic acid (LPA), a prototypical ligand for G protein coupled receptors, and Forkhead box protein M1 (FOXM1), a transcription factor that regulates expression of a wide array of genes involved in cancer initiation and progression, are two ...

Inflammatory Mediators Both Directly and Indirectly Promote Microglial Proliferation

Glia, Volume 74, Issue 5, May 2026.
– CSF2, IL3, and TNFɑ directly promote microglial proliferation. – Neuron‐secreted factors suppress microglial proliferation. – IL1 cytokines promote CSF2 release from astrocytes, which promotes microglial proliferation. ABSTRACT Microglia—the predominant immune cell of the central nervous system (CNS)—possess an astounding capacity for proliferation ...

Inhibition of lysophosphatidic acid receptor 1–3 deteriorates experimental autoimmune encephalomyelitis by inducing oxidative stress

Journal of Neuroinflammation, 2021
Background Lysophosphatidic acid receptors (LPARs) are G-protein-coupled receptors involved in many physiological functions in the central nervous system. However, the role of the LPARs in multiple sclerosis (MS) has not been clearly defined yet. Methods

Sphingosine 1-phosphate receptors: do they have a therapeutic potential in cardiac fibrosis? [PDF]

, 2017
Sphingosine 1-phosphate (S1P) is a bioactive lipid that is characterized by a peculiar mechanism of action. In fact, S1P, which is produced inside the cell, can act as an intracellular mediator, whereas after its export outside the cell, it can act as ...

Lipidome Analysis of Cancer Cells and Their Extracellular Vesicles Reveals Cancer‐Type‐Specific Lipid Signatures and Enables the Design of EV‐Mimetic Liposomes

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT Lipid metabolism reprogramming is a hallmark of cancer, yet the global lipidome of cancer cells and their extracellular vesicles (EVs) remains poorly understood. Using mass spectrometry, we analyzed the lipid profiles of a panel of human cancer and non‐cancer cell lines along with their secreted EVs.
