In contrast, mRNA expression of enzymes involved in the biosynthesis of glycosphingolipids, including glucosylceramide synthase (UCGC), and lactosylceramide synthases B4GALT5 and B4GALT6, were elevated in CAV1-high prostate cancer cell lines and prostate tumors (Fig. 3a, b). Here, UGCG is linked to prostate neoplasm.
