Abstract:
Growing evidence indicates that antisense oligodeoxynucleotides can specifically inhibit gene expression thereby providing an essential tool for understanding gene function and the potential to affect abnormal cell proliferation. Because oncogene activation is intimately involved in tumour initiation and progression, down-regulation of oncogene expression is associated with a selective or a preferential inhibition of tumour as compared to normal cell proliferation. Even though numerous studies attest the short-term in vitro efficacy of antisense oligodeoxynucleotides as inhibitors of tumour growth, the use of these compounds as therapeutic agents awaits a more rigorous demonstration of their long term effects and favourable pharmacological properties.
Insights
Antisense oligodeoxynucleotides can inhibit gene expression to study cell proliferation. While effective in the short term for tumor growth, their long-term therapeutic use requires further study.
