PubReading [17] - Antisense, RNAi, and gene silencing strategies for therapy: Mission possible or impossible? - E. Rayburn and R. Zhang

<p><strong>Antisense oligonucleotides</strong> can regulate gene expression in living cells. As such, they regulate cell function and division, and can modulate cellular responses to internal and external stresses and stimuli. Although encouraging results from preclinical and clinical studies have been obtained and significant progress has been made in developing these agents as <strong>drugs</strong>, they are not yet recognized as effective therapeutics. Several major hurdles remain to be overcome, including problems with efficacy, off-target effects, delivery and side effects. The lessons learned from antisense drug development can help in the development of other <strong>oligonucleotide-based therapeutics</strong> such as <strong>CpG</strong> oligonucleotides, <strong>RNAi</strong> and <strong>miRNA. </strong>-<strong> </strong>doi:10.1016/j.drudis.2008.03.014 - 2008</p>
