Fig. 1From: Identification of circulating sphingosine kinase-related metabolites for prediction of type 2 diabetesCirculating levels of SphK-related sphingolipids in Sphk1−/− and Sphk2−/− mice. Levels of circulating SphK-related sphingolipids, including sphingosine (Sph), sphingosine 1-phosphate (S1P), dihydro-Sph (dhSph) and dhS1P were measured in Sphk1−/−, Sphk2−/− and wild-type (WT) mice (n = 7 per group). Ratios of S1P/Sph and dhS1P/dhSph are shown in the right panels. Data are expressed as means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
