Abstract
Owing to its capability of discriminating subtle mass-altering structural differences such as double bonds or elongated acyl chains, MALDI-based imaging MS (IMS) has emerged as a powerful technique for analysis of lipid distribution in tissue at moderate spatial resolution of about 50 μm. However, it is still unknown if MS(1)-signals and ion intensity images correlate with the corresponding apparent lipid concentrations. Analyzing renal sulfated glycosphingolipids, sulfatides, we validate for the first time IMS-signal identities using corresponding sulfatide-deficient kidneys. To evaluate the extent of signal quenching effects interfering with lipid quantification, we surgically dissected the three major renal regions (papillae, medulla, and cortex) and systematically compared MALDI IMS of renal sulfatides with quantitative analyses of corresponding lipid extracts by on-target MALDI TOF-MS and by ultra-performance LC-ESI-(triple-quadrupole)tandem MS. Our results demonstrate a generally strong correlation (R(2) > 0.9) between the local relative sulfatide signal intensity in MALDI IMS and absolute sulfatide quantities determined by the other two methods. However, high concentrations of sulfatides in the papillae and medulla result in an up to 4-fold signal suppression. In conclusion, our study suggests that MALDI IMS is useful for semi-quantitative dissection of relative local changes of sulfatides and possibly other lipids in tissue.

Higher expression of renal sulfoglycolipids in marine mammals. Glycoconj J 2008; 25:723-6.

Abstract
Patterns and contents of major acidic glycosphingolipids in the kidney of three marine mammalian species, the Steller sea lion (Pinnipedia), the rough-toothed dolphin and the broad-beaked dolphin (Odontoceti), were examined, and compared with those of terrestrial mesic mammals. The profile of major acidic glycosphingolipids was not significantly different between the terrestrial and marine mammals: predominant gangliosides were GM3 and GD3, and major sulfoglycolipids were SM4s and SM3. On the other hand, the total concentration (nmol/g wet tissue) of sulfoglycolipids was considerably higher in the marine mammals (2.3-3.0 times) than that in the terrestrial mesic mammals with comparable body weights. In contrast, there was no significant difference in the level of renal glycolipids-bound sialic acid between the marine and the terrestrial mammals. These results suggest that higher expression of renal sulfoglycolipids in marine mammals may contribute to the maintenance of osmotic balance of their body fluid against sea water.

Abstract
Effects of a glycolytic (glucose) and a gluconeogenic renal nutritional substrate (glutamine) on metabolic turnover of sulfolipids, determined as [(35)S]sulfate incorporation, were compared in renal tubules prepared from well-fed rats. The results showed that the effects of glucose and glutamine, at nearly physiological serum concentration, are quite contrary to each other. Glucose increased the turnover rates of relatively long chain ganglio-series sulfoglycolipids (Gg(3)Cer II(3)-sulfate and Gg(4)Cer II(3),IV(3)-bis-sulfate) (1.7 to 2.4-fold), but not of cholesterol 3-sulfate (0.9-fold). In contrast, glutamine accelerated the turnover rates of relatively short chain sulfoglycolipids (glucosyl sulfatide, galactosyl sulfatide and lactosyl sulfatide) (1.3 to 2.7-fold), as well as cholesterol 3-sulfate (2.4-fold). The possible mechanism which causes these marked differences is also discussed.

Abstract
Incorporation of (35)S-sulfate into the polar molecular species of sulfoglycolipids (SM4s) in Madin-Darby canine kidney cells increased in a hypertonic medium (500 mOsm/L) supplemented with sodium chloride. The unknown sulfoglycolipid (SX) was identified as GlcCer sulfate based on the results of TLC, GLC, and mass spectra. The synthesis of SX increased in the hypotonic medium unlike that of SM4s and SM3. TLC showed that hypertonic stress induced the accumulation of GalCer as a precursor of SM4s, whereas hypotonic stress increased GlcCer as a precursor of GlcCer sulfate. The level of ceramide as a precursor of both GalCer and GlcCer increased under hypertonic stress and decreased under hypotonic stress. Cerebroside sulfotransferase mRNA was shown to be elevated in the hyperosmotic condition but not in the hypotonic condition. The increase in SM4s under hypertonic stress was induced by the activation of both the ceramide galactosyltransferase and the cerebroside sulfotransferase genes, whereas the increase in GlcCer sulfate under hypotonic stress was caused by the accumulation of GlcCer as the result of activation of ceramide glucosyltransferase.
