Fig 2
Vitamin B6 vitamers levels are reduced in aldh7a1 homozygous knock-out embryos relative to the wildtype. It is shown in a scatterplot of quantification of the levels of vitamin B6 vitamers in aldh7a1 homozygous knock-out zebrafish relative to the wildtype as measured by LC-MS. The graph demonstrates decreased levels of vitamin B6 vitamers in aldh7a1 knock-out 11 dpf embryos (aldh7a1 knock-out, grey squares) relative to the age-matched wildtype control embryos (Wildtype, black circles). Each dot represents metabolite data collected from 20 embryos. For a single data point of homozygous aldh7a1 knock-out zebrafish, only 16 embryos were available, so that data point was excluded from the analysis. nd, not detectable–the levels of metabolites could not be measured. p values were calculated by unpaired student t-test for multiple measurements followed by Holm-Sadak correction for multiple analysis. Error bars, SD.
