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

Advanced Science, EarlyView.
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.

Single-cell sequencing analysis related to sphingolipid metabolism guides immunotherapy and prognosis of skin cutaneous melanoma

Frontiers in Immunology, 2023
BackgroundWe explore sphingolipid-related genes (SRGs) in skin melanoma (SKCM) to develop a prognostic indicator for patient outcomes. Dysregulated lipid metabolism is linked to aggressive behavior in various cancers, including SKCM.

Functional identification of a delta8-sphingolipid desaturase from Borago officinalis

, 2001
The similarities between Δ12- and Δ15-fatty acyl desaturase sequences were used to construct degenerate primers for PCR experiments with cDNA transcribed from mRNA of developing borage seeds.

FUCA2 Sustains AKT Signaling and Suppresses Senescence by Antagonizing FUT3‐Mediated ErbB3 Fucosylation in Lung Adenocarcinoma

Advanced Science, EarlyView.
ABSTRACT While targeted therapies have improved outcomes in lung adenocarcinoma (LUAD), many patients still lack targetable mutations. Here, we identified alpha‐L‐fucosidase 2 (FUCA2) as a crucial driver of LUAD by preventing cellular senescence. Mechanistically, through the restriction of fucosyltransferase 3 (FUT3)‐mediated α‐1,3‐fucosylation of ...

Localized Accumulation of Tri‐n‐Propylamine Prolongs Electrochemiluminescence for Tumor Model Spheroid Analysis

Angewandte Chemie, EarlyView.
Here, we enhance the electrochemiluminescence imaging of cellular spheroids using [Ru(bpy)3]2+/TPrA chemistry. Our strategy, which involves pre‐incubation with TPrA, enables high‐resolution, long‐term visualization of cellular spheroids without phototoxicity.

Glucosylceramide synthesis inhibition affects cell cycle progression, membrane trafficking, and stage differentiation in Giardia lamblia[S]

Journal of Lipid Research, 2010
Synthesis of glucosylceramide via glucosylceramide synthase (GCS) is a crucial event in higher eukaryotes, both for the production of complex glycosphingolipids and for regulating cellular levels of ceramide, a potent antiproliferative second messenger ...

The sphingolipid anteome: implications for evolution of the sphingolipid metabolic pathway

FEBS Letters, 2022
Modern cell membranes contain a bewildering complexity of lipids, among them sphingolipids (SLs). Advances in mass spectrometry have led to the realization that the number and combinatorial complexity of lipids, including SLs, is much greater than previously appreciated.

Chimeras of delta6-fatty acid and delta8-sphingolipid desaturases

, 2000
The Borago officinalis Delta6 fatty acid desaturase (Boofd6) shares 58% identity in its amino acid sequence with Boofd8, a Delta8 sphingolipid desaturase from the same plant species.

BIN1 and ALDH1B1 Deficiency in Colonic Smooth Muscle Drives Mitochondrial Dysfunction and Fibrosis in Slow‐Transit Constipation

Advanced Science, EarlyView.
Slow‐transit constipation (STC) is a disabling motility disorder with unclear smooth‐muscle mechanisms. Spatial proteomic analysis of STC patient colon reveals both the central pathogenic role of smooth muscle cells (SMCs) in STC and novel regulators of intestinal motility, BIN1 and ALDH1B1.

Aziridine ring opening for the synthesis of sphingolipid analogues: Inhibitors of sphingolipid-metabolizing enzymes [PDF]

, 2014
A library of sphingolipid analogues is designed and tested as inhibitors against mammalian and fungal sphingolipid enzymes. The synthesis of sphingolipid analogues is based on the nucleophilic ring-opening reactions of N-activated aziridine derivatives ...
