Genetic and biochemical characterisation of the smpd1^−/− mutant zebrafish line. (A) Representative genotyping gel of the smpd1^−/− alleles (5 bp deletion and 136 bp insertion) demonstrating WT, smpd1^+/− and smpd1^−/−. (B) Acid sphingomyelinase (ASM) enzymatic activity in smpd1^−/− compared to WT controls (n=6 larvae at 5 dpf per genotype, P=0.006 by two-tailed unpaired Welch's t-test). (C) Quantification of sphingolipid metabolites, namely, sphingomyelin (Sph), dihydro-sphingomyelin (DHSph), ceramide (Cer), lactosylceramide (LacCer), sphinganine (Spgn) and sphinganine 1 phosphate (Sa1P). All metabolites shown are the C18 neuronal species. Data represented are the mean±s.d. *P<0.05; **P<0.01; ***P<0.001 (two-tailed unpaired t-test).
