Effect of Efhc2 knock-down on pronephros development and function. a Schematic representation of the binding of the splice-blocking efhc2 morpholino (efhc2-MO) targeting exon-3 and the forward and reverse primers used in RT-PCR to verify its effect. RT-PCR on RNA extracted from 24 hpf uninjected embryos or embryos injected with efhc2-MM control showed a 651Â bp product as expected. The embryos injected with efhc2-MO showed a 311Â bp fragment confirming the blocking of normal splicing of efhc2 by this morpholino. b efhc2-Mo morphants showed morpholino dose-dependent developmental defects as compared with wild-type and mismatch controls. Arrow indicates mild pericardial oedema and arrowhead indicates hydrocephalus. c Fluorescent 40Â kDa dextran was injected into cardinal vain of control and efhc2-Mo morphants at 48Â hpf. Accumulation of dextran in yolk and oedema shows defects in pronephros function in efhc2-Mo morphants at 72 and 96 hpf
