An efficient targeting delivery technology is needed for functional oligonucleotides to exert their potential effect on the target gene without an adverse effect  in vivo . Development of enteral delivery systems for nucleic acids is a major challenge because of their large molecular size and instability. Here, we describe a new enteral delivery technique that enables small interfering RNA (siRNA) selectively delivered to the liver to silence its target  Apolipoprotein B  gene expression. A nuclease-resistant synthetic siRNA was conjugated with α-tochopherol and administered as lipid nanoparticle to the large intestine of the mice in a postprandial state. The selective transport into the liver, effective gene silence, and consequently significant reduction in serum low density lipoprotein-cholesterol level, were demonstrated. The chylomicron-mediated pathway via the lymphatic route was suggested as major mechanism. This unique approach may provide a basis for developing oral and rectal delivery systems for nucleic acids targeting liver.
