A4GALT and ovarian carcinoma: In ovarian cancer patient samples a consistent decrease of most of the analyzed lipid classes was observed, including phosphatidylcholines (PCs), phosphatidylethanolamines (PEs), phosphatidylinositols (PIs), cholesterylesters (CEs), diacylglycerols (DAGs), sphingomyelins (SMs), cerebrosides (glucosyl/galactosylceramides (Glc/GalCers), lactosylceramides (LacCers)), globotriasoylceramides (Gb3s) and sphingosine-1-phosphates (S1Ps) (Figure 1A, Supplementary Table 2).
