Use of Antisense Oligonucleotides or siRNA to Suppress Expression of eIF-5A1

Abstract

The present invention relates to apoptosis specific eucaryotic initiation factor 5A (eIF-5A), referred to as apoptosis factor 5A1 or simply factor 5A1, apoptosis factor 5A1 nucleic acids and polypeptides and methods for inhibiting or suppressing apoptosis in cells using antisense nucleotides or siRNAs to inhibit expression of factor 5A1. The invention also relates to suppressing or inhibiting expression of pro-inflammatory cytokines by inhibiting expression of apoptosis factor 5A.

1 .- 36 . (canceled) 
     
     
         37 . An siRNA for suppressing expression of apoptosis-specific eIF-5A1 wherein the siRNA is double-stranded for 19-25 nucleotides in length. 
     
     
         38 . The siRNA of  claim 37 , wherein the siRNA has at least one single-stranded overhang region, with each single-stranded region comprising six or fewer nucleotides. 
     
     
         39 . The siRNA of  claim 38 , wherein the siRNA has two single-stranded overhang regions. 
     
     
         40 . The siRNA of  claim 39 , wherein each of the two single-stranded overhang regions comprise two nucleotides or less. 
     
     
         41 . The siRNA of  claim 40 , wherein the double-stranded region on the siRNA is 19-21 nucleotides in length. 
     
     
         42 . The siRNA of  claim 41 , wherein the double-stranded region on the siRNA is 21 nucleotides in length. 
     
     
         43 . The siRNA of  claim 41 , wherein the double-stranded region on the siRNA is 19 nucleotides in length.
