Transient ectopic expression of multiple potassium channel genes also induces long-finned phenotype. (A) WT adult control fish without any injection. (B) Representative injected adult F₀ fish image of human KCNJ13. Note: a barbel is also elongated in this fish. (C) Representative injected adult F₀ fish image of zebrafish kcnj10a. (D) Representative injected adult F₀ fish image of zebrafish kcnj1b. (E) Representative injected adult F₀ fish image of zebrafish kcnk9. (F) Representative injected adult F₀ fish image of zebrafish kcna1a. Arrows indicate the potions of the elongated parts of fins. All the potassium channel genes are driven by the actinb promoter. The partial and variable elongated fins are due to the mosaic nature of Tol2 injection. Bars, 5 mm. WT, wild-type.
