After processing by Di… In higher eukaryotes, RNAi-mediated knockdown is the most common strategy for depleting cells of a gene product of interest. Two key approaches to RNAi that have gained substantial interest for use in gene silencing are the double-stranded small interfering RNAs (siRNAs) and the vector-based short hairpin RNAs (shRNAs). Transient gene knockdown in zebrafish larvae is readily accomplished through the deployment of morpholino oligonucleotides (MOs) (Bill et al., 2009).MOs can be targeted to block translation of a target mRNA, by hybridization to the ATG initiation codon, or to prevent correct splicing by annealing to exon-intron splice signals in the pre-mRNA (Eisen and Smith, 2008) (Figure 7.4). Importantly, reversal of p53-dependent cell death by p53 knockdown does not affect specific loss of gene function, such as the cell death caused by loss of function of chordin.
