"The current textbooks for medical students do not have chapters on antisense oligonucleotides, but this will change in the near future," said Thornton ... "As compared to conventional drugs that work on proteins, antisense oligonucleotides work on RNA. They have been around for 20 years, but only recently is their full potential being realized. They provide... (Science Daily)

    Gene Inhibition May Help Normalize Type 2 Diabetes  Jun 20, 2009
    At the same time, they inhibited expression of the Sirtiun 1 gene through injection of an antisense oligonucleotide (short fragments of nucleic acid that inactivate gene expression) specifically targeted to that gene. Blood glucose levels in the rats came down close to normal, as did their ability to regulate blood glucose levels with insulin, said first author Derek Erion, a graduate student in cellular and molecular physiology at Yale.
