Restoration of cilia defects in Inpp5b zebrafish morphants by mouse Inpp5b mRNA. (A) Inpp5b WT mRNA rescued the loss of inpp5b. KV cilia of zebrafish embryos injected with control MO (4 ng), inpp5b MO (4 ng) or inpp5b MO (4 ng) and Inpp5b WT mRNA (500 ng) at 6-somite stage were immunostained with acetylated alpha-tubulin (red), representative images are shown (dash line indicates border of KV). Scale bar 10 micron. (B-C) Quantification of number (B) and length (C) of KV cilia in zebrafish embryos injected with control MO (4 ng), inpp5b MO (4 ng) or inpp5b MO (4 ng) and Inpp5b WT mRNA (500 ng). (D) Inpp5b WT mRNA rescue of inpp5b pronephric cilia formation. Representative image of pronephric cilia of zebrafish embryos at 24 hpf stage, injected with control MO (4 ng), inpp5b MO (4 ng) or inpp5b MO (4 ng) and Inpp5b WT mRNA (500 ng), immunostaining with acetylated α-tubulin (red). Scale bar 10 micron. (E) Pronephric cilia length of control and inpp5b MO. Pronephric cilia of zebrafish embryos injected with control MO (4 ng), inpp5b MO (4 ng) or inpp5b MO (4 ng) and Inpp5b WT mRNA (500 ng) at 24 hpf stage were analyzed by immunostaining with acetylated alpha-tubulin and cilia length was measured. (F) Inpp5b-delta-CAAX mRNA failed to rescue the loss of inpp5b. KV cilia of zebrafish embryos injected with inpp5b MO (4 ng), inpp5b MO (4 ng) with Inpp5b WT mRNA (500 ng) and inpp5b MO (4 ng) with Inpp5b-delta-CAAX mRNA (500 ng) at 6-somite stage were immunostained with acetylated alpha-tubulin (red), representative images are shown (dash line indicates border of KV). Scale bar 10 micron. (G) Quantification of length of KV cilia in zebrafish embryos injected with inpp5b MO (4 ng), inpp5b MO (4 ng) with Inpp5b WT mRNA (500 ng) and inpp5b MO (4 ng) with Inpp5b-delta-CAAX mRNA (500 ng) (6.5+0.5 micron in morphants of inpp5b MO with Inpp5b mRNA compared to 4.7+0.4 micron in morphants of inpp5b MO with Inpp5b-delta-CAAX mRNA, unpaired t-test, * p = 4.9E-07, N >20 embryos, three independent experiments).
