Targeting progressive multiple sclerosis: Toward mechanism‐informed precision medicine

Journal of Internal Medicine, Volume 300, Issue 3, Page 238-257, September 2026.
Abstract Multiple sclerosis has undergone a therapeutic revolution over the past three decades. Randomized clinical trials and real‐world data demonstrate that modern disease‐modifying therapies substantially reduce relapse rates and acute inflammatory activity detected by magnetic resonance imaging (MRI).

MEOX1 Coordinates Autocrine‐Paracrine Programs via SPHK1/S1P to Promote Lymph Node Metastasis in Ovarian Cancer

Advanced Science, Volume 13, Issue 43, 3 August 2026.
In ovarian cancer, MEOX1 activates the SPHK1/S1P pathway to promote both tumor progression and tumor–stroma crosstalk. MEOX1‐dependent signaling drives CAF activation, enhances VEGF‐C expression, and stimulates lymphangiogenesis, ultimately facilitating lymph node metastasis.

Lung Pericytes: Molecular Mechanisms, Signaling Pathways, and Roles in Pulmonary Diseases

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
Central role of pericytes across major pulmonary diseases. Conceptual wheel diagram illustrating the central role of lung pericytes across diverse pulmonary disease states. A pericyte positioned at the center expresses canonical markers, including PDGFRβ, CD146, and NG2, and connects radially to five major disease contexts.

Sphingosine‐1‐Phosphate Receptor 1 Regulates Competition Dependent Astrocyte Morphogenesis and Tiling in Murine Cortex

Glia, Volume 74, Issue 8, August 2026.
Neuronal contact‐induced expression of S1PR1 in astrocytes is regulated by JAK‐STAT3 signaling. Astrocytic S1PR1 modulates cortical astrocyte morphogenesis. Astrocytic S1PR1 regulates astrocyte territorial overlap/tiling in a competition dependent manner.

Sphingosine‐1‐Phosphate Receptor 1 Promotes Ovarian Cancer Tumorsphere Proliferation and Metastasis

International Journal of Cancer, Volume 159, Issue 3, Page 768-781, 1 August 2026.
In high‐grade serous ovarian cancer, malignant ascites frequently arise as ovarian cancer cells shed from the primary tumor and aggregate into tumorspheres, severely limiting treatment success. To date, little is known about the mechanisms governing tumorsphere endurance and metastasis within the ascites once formed.

Sphingosine analogue drug FTY720 targets I2PP2A/SET and mediates lung tumour suppression via activation of PP2A‐RIPK1‐dependent necroptosis

EMBO Molecular Medicine, 2012
Mechanisms that alter protein phosphatase 2A (PP2A)‐dependent lung tumour suppression via the I2PP2A/SET oncoprotein are unknown. We show here that the tumour suppressor ceramide binds I2PP2A/SET selectively in the nucleus and including its K209 and Y122

Myocardial Lipid Metabolism Imbalance: The Pathological Core and Novel Diagnostic‐Therapeutic Directions of Cardiovascular Diseases

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
In cardiac cells, Plin5/AMPK regulate lipid homeostasis; excess CD36‐mediated uptake drives lipotoxicity, mitochondrial dysfunction, and CVDs (e.g., heart failure). Biomarkers (ApoB/ApoA‐1) and therapies (SGLT2 inhibitors) target this cascade. ABSTRACT Cardiac lipid metabolism is fundamental to myocardial energy homeostasis, with fatty acid oxidation ...

Palmitate increases sphingosine-1-phosphate in C2C12 myotubes via upregulation of sphingosine kinase message and activity[S]

Journal of Lipid Research, 2009
Studies in skeletal muscle demonstrate that elevation of plasma FFAs increases the sphingolipid ceramide. We aimed to determine the impact of FFA oversupply on total sphingolipid profiles in a skeletal muscle model.
