A small nucleic acid molecule that down-regulates expression of Wrap53 gene via RNA interference (RNAi), wherein at least one strand of said small nucleic acid molecule is about 15 to about 30 nucleotides in length; and wherein at least one strand of said small nucleic acid molecule comprises a nucleotide sequence having sufficient complementarity to an RNA of said Wrap53 gene for the small nucleic acid molecule to direct cleavage of said RNA via RNA interference, for use as a medicament.
