In a search to identify chemical modifications to improve the properties of siRNA, we ham investigated the effect of the 2'-O-methyl-2-thiouridine modification on the biological activity of siRNA. Our results indicate that judicious placement of 2'-O-methyl-thiouridine residues could lead to modified siRNA with activity in mammalian cells.
