Fig. S1 In vivo validation of NDRG4 MO1 (knockdown by translation-blocking). (A) Schematic of the strategy to target the translational start site with NDRG4 MO1. (B) Schematic map of a transgenic construct in which the cmlc2 promoter is upstream of an NDRG4-EYFP fusion DNA. H19 insulators in the pWhere plasmid (InvivoGen) flanked the cmlc2-NDRG4-EYFP DNA fragment, which includes the binding region of NDRG4,/em> MO1. (C) After Co-injection of the linearized DNA with 6.4 ng of control MO (a) or NDRG4 MO1 (b) into wildtype embryo at one-cell stage, green fluorescent signals due to NDRG4-EYFP expression in cardiomyocytes were observed in 7.9% (control MO) or 0% (NDRG4 MO1) of injected embryos at 48 hpf. Arrow indicates the heart region.
