RNA interference is a convenient and highly effective technique to investigate the biological function of genes. Adequately designed RNA molecules introduced into an oocyte are able to bind specific endogenous mRNAs and trigger their degradation. Subsequent fertilization of these oocytes will result in the generation of embryos in which the expression of the gene of interest is downregulated, and following the degradation of maternal proteins the role of the gene product can be studied. Here, we describe the approach how post-transcriptional gene silencing can be achieved in oocytes and early embryos using siRNA.
