Increased lactosylceramide synthase (GalT-V) level in APOE−/− mice is reversed upon treatment with D-PDMP/ BPD. Skin tissue from ApoE−/− mice fed normal chow or western diet with and without treatment with D-PDMP and BPD were homogenized in RIPA buffer, centrifuged and the supernatant used as a source of lactosylceramide synthase (GalT-V). The mass of GalT-V was measured using an ELISA assay and antibody raised against this antigen. We observed increased mass of GalT-V in placebo mice compared to control mice. Conversely, treatment with BPD decreased the mass of GalT-V, with 1BPD being more effective than 5BPD in skin tissue. A nonparametric one –way ANOA using the Bonferroni’s multiple comparison p test was performed. *p < 0.05, **p < 0.001, ***p < 0.001; n = 3–5.
