We performed a pilot clinical trial with safingol (L-threo-dihydrosphingosine), a protein kinase C-specific inhibitor that potentiates the effect of doxorubicin (DOX) in tumor-bearing animals. Safingol was initially administered as a 1-h infusion at escalating doses. Fourteen days later, patients received

Triple-negative breast cancer (TNBC) is a highly heterogeneous and recurrent subtype of breast cancer that lacks an effective targeted therapy. To identify candidate therapeutic targets, we profiled global gene expression in TNBC and breast tumor-initiating cells with a patient survival

The sphingosine analog L-threo-dihydrosphingosine has been shown to inhibit protein kinase C (PKC) isoenzymes in mixed micelle and vesicle assays. This compound also inhibited the reactive oxygen intermediates (ROI) released from isolated neutrophils (IC50 approximately 2 microM) and phorbol ester-induced

The immunomodulatory glycolipid α-galactosylceramide (α-GalCer) binds to CD1d and exhibits potent activity as a ligand for invariant CD1d-restricted natural killer-like T cells (iNKT cells). Structural analogues of α-GalCer have been synthesised to determine which components are required for CD1d presentation

Sphingoid intermediates accumulate in response to a variety of stresses, including heat, and trigger cellular responses. However, the mechanism by which stress affects sphingolipid biosynthesis has yet to be identified. Recent studies in yeast suggest that sphingolipid biosynthesis is regulated
