Nucleic acids, polypeptides, compositions, and methods for modulating apoptosis
The present invention relates to isolated and/or purified rat apoptosis-specific eucaryotic initiation Factor-5A (eIF-5A) and deoxyhypusine synthase (DHS) nucleic acids and polypeptides. The present invention also relates to methods of modulating apoptosis using apoptosis-specific eIF-5A and DHS, and antisense oligonucleotides and expression vectors of apoptosis-specific eIF-5A and DHS useful in such methods.
1. A method for increasing apoptosis in vitro in a mammalian cell comprising administering to the cell a polynucleotide encoding apoptosis-specific eIF-5A comprising SEQ ID NO: 1 wherein said apoptosis-specific eIF-5A is expressed within the cell thereby increasing apoptosis in the cell as compared to the level of apoptosis in cells not having been administered said polynucleotide.
2. The method of claim 1 , wherein the polynucleotide encoding apoptosis-specific eIF-5A is in an expression vector.
