Levels of ceramide species in cultured primary myoblasts from wild-type and VCPR155H/R155H mice
Ceramide | Mean ± SEM (nmol/mg protein) | |
---|---|---|
WT | HZ | |
(d18:1/16:0) | 2.34 ± 0.30 | 30.82 ± 4.86*** |
(d18:1/18:0) | 0.10 ± 0.01 | 0.92 ± 0.16*** |
(d18:1/24:1) | 0.96 ± 0.11 | 6.36 ± 1.24*** |
(d18:1/24:0) | 0.87 ± 0.13 | 3.69 ± 0.59*** |
Levels of cellular ceramide were quantified from primary myoblasts in culture. Cells from the WT (at passage 8 in vitro) and VCPR155H/R155H (HZ, at passage 7) mice were cultured and scraped into methanol. The lipids were extracted with chloroform and the levels of various ceramide species were determined by using LC–MS/MS (n = 5–6). Data are expressed as mean ± SEM. ***P < 0.001 by two-tailed t-test.
