Abstract:
The present invention relates to unique isoforms of eukaryotic initiation Factor 5A ("eIF-5A"): senescence-induced eIF-5A; wounding-induced eIF-5A; and growth eIF-5A, as well as polynucleotides that encode these three factors. The present invention also relates to methods involving modulating the expression of these factors. The present invention also relates to deoxyhypusine synthase ("DHS"), polynucleotides that encode DHS, and methods involving modulating the expression of DHS.
Abstract:
Regulation of expression of programmed cell death, including senescence, in plants is achieved by integration of a gene or gene fragment encoding senescence-induced eIF-5A or both into the plant genome in antisense orientation. Plant genes encoding senescence-induced deoxyhpusine synthase and senescence-induced elF-5A are identified and the nucleotide sequences of each, aon and in combination are used to modify senescence in transgenic plants
Abstract:
Senescence in perishable plant tissue is inhibited by the application thereto of an effective amount of a compound of formula (I), wherein R1, R2, R3, R4 and R5 are each selected from the group consisting of hydrogen, -OH or -OR7, provided that at least one of R1 to R5 is a hydroxyl group, R6 is selected from the group consisting of -OH, -OR8 and -NHR9, R7 is a substituent group, R8 is the residue of an ester-forming compound and R9 is the residue of an amide-forming compound. The compound may be prepared synthetically and, in some cases, can be isolated from natural sources, for example, the glucose ester of ferulic acid may be isolated from carnation petals.
Abstract:
The present invention relates to the combinatorial use of an siRNA targeted against an endogenous gene to knock out or knock down expression of the endogenous gene in a host and a delivery of a polynucleotide encoding the gene in a delivery vehicle/expression vector to the host to provide expression in the host of the protein encoded by the polynucleotide.
Abstract:
The present invention relates to apoptosis specific eucaryotic initiation factor 5A (eIF-5A), referred to as apoptosis-specific eIF-5A or eIF5A1, nucleic acids and polypeptides and methods for inhibiting or suppressing apoptosis in cells using antisense nucleotides or siRNAs to inhibit expression of apoptosis-specific eIF-5A. The invention also relates to suppressing or inhibiting expression of pro-inflammatory cytokines or inhibiting expression of pro-inflammatory cytokines or inhibiting activation of NFkB by inhibiting expression of apoptosis-specific eIF-5A.
