Identification of slc1a4 mutant zebrafish. (a) Schematic of Cas9-sgRNA targeted site located in first exon of slc1a4. (b) Schematic of complex injected into one-cell embryos. (c) Procedure for obtaining slc1a4−/− mutant lines. (d) Representative sequencing results of wild-type and mutated zebrafish lines. Mutant sequencing results showed that 10 bp were deleted in slc1a4−/− zebrafish. (e,f) Western blotting analysis showed that Slc1a4 protein expression is inhibited in mutant group compared with wild type. Protein expressions were quantified by Image J software version 1.54f. Experiment was repeated three times with three independent samples. **** p < 0.0001. Assessed by unpaired t-test.
