Abstract

An advantage of using N-([1-14C]hexanoyl)sphingolipids to assay sphingolipid metabolism is their ability to rapidly and spontaneously transfer into biological membranes without destroying membrane integrity. This property allows analysis of the activity of enzymes of sphingolipid metabolism under conditions in which the rate of product formation is not limited by availability of substrate, as is often the case with naturally occurring lipids whose rates of spontaneous transfer are extremely slow.21.22 Thus, the use of N-([1-14C]hexanoyl)sphingolipids provides an alternative means for studying sphingolipid metabolism in vitro.

      In addition, liver extracts of Sortilin−/− mice after BDL showed reduced expression of IL-6, TNF-α, and interferon-γ, particularly 3 and 7 days after BDL (Supplemental Figure S2). Serum levels of hepatic enzymes are increased 2 days after BDL, which is the starting point for development of chronic injury and repair process from 7 to 14 days.34 Indeed, serum levels of aspartate aminotransferase, alkaline phosphatase, and total serum bile acids, but not alanine aminotransferase, were significantly lower in Sortilin−/− mice 3 days after BDL, as compared to WT mice (Figure 3A), indicating reduced hepatocellular and cholestatic damage.

      Blots were incubated with antibodies to pAkt (dilution 1:1000, Cell Signaling Technology, Danvers, MA) and Akt1/2 (dilution 1:1000), fatty acid synthase (FAS) (dilution 1:1000) or β-actin (dilution 1:5000) (Santa Cruz Biotechnology, Santa Cruz, CA), then incubated with horseradish peroxidase-conjugated secondary antibodies and subjected to chemiluminescent detection. aSMase activity from liver and adipose tissue extracts was assessed as described [18–19]. Briefly, liver or adipose tissue was homogenated in sodium acetate buffer (50 mM sodium acetate, pH 4.5) with protease inhibitor (Sigma).

      Initial experiments using C6-NBD-ceramide demonstrated that this lipid was internalized by a non-energy-dependent mechanism, and subsequently accumulated in the Golgi apparatus [15,16] where it was metabolized to C6-NBD-sphingomyelin (C6-NBD-SM) and C6-NBD-glucosylceramide (C6-NBD-GlcCer) [17]), suggesting that the Golgi apparatus was the major site of ceramide metabolism rather than the other intracellular sites which had been proposed earlier. Based on this work, it was later shown by biochemical studies, using short-acyl chain radioactive ceramides [18], that the Golgi apparatus is indeed the site of ceramide metabolism to SM [19,20] and GlcCer [21,22], and taken together with the demonstration that ceramide is synthesized in the endoplasmic reticulum (ER) [23,24], lead to the concept that SL synthesis is compartmentalized between the ER and the Golgi apparatus [25]. This being the case, ceramide would need to be transported between the ER, its site of synthesis, and the Golgi apparatus, its site of further metabolism.
