drugs. In the fight against cancer, antisense drugs, which prevent genes from
producing harmful proteins such as those that cause cancer, have the promise to
be more effective than conventional drugs, but the pace of development of these
new drugs has been slow. Using gold nanoparticles combined with DNA, scientists
at Northwestern University now have demonstrated a new method for developing
antisense drugs that outperform conventional antisense agents. The findings will
be published May 19 in the journal Science. (EurekAlert 5.18.06)<BR><A
