To determine which of these populations may be linked to scoliosis, we performed whole mount immunohistochemistry on 21- and 30-day old katnb1mh102/mh102 mutant versus control brains and screened for alterations in polyglutamylated tubulin (PolyETub) staining, which is a reliable marker for cilia on foxj1-expressing cells in zebrafish (Bré et al., 1994; D’Gama et al., 2021). This evidence concerns the gene FOXJ1 and scoliosis.
