Abstract:
Oligonucleotide surrogates comprising a plurality of cyclobutyl moieties covalently joined by linking moieties are prepared and used as antisense diagnostics, therapeutics and research reagents. Methods of synthesis and use of both the oligonucleotide surrogates and intermediates thereof are disclosed.
Abstract:
Compositions and methods are provided for the treatment and diagnosis of diseases amenable to modulation of the synthesis or metabolism of arachidonic acid and related compounds. In accordance with preferred embodiments, oligonucleotides and oligonucleotide analogs are provided which are specifically hybridizable with nucleic acids encoding 5-lipoxygenase, 5-lipoxygenase activating proteins, LTA4 hydrolase, phospholipase A2, phospholipase C, and coenzyme A-independent transacylase. The oligonucleotide comprises nucleotide units sufficient in identity and number to effect said specific hybridization. In other preferred embodiments, the oligonucleotides are specifically hybridizable with a transcription initiation site, a translation initiation site, and intron/exon junction. Methods of treating animals suffering from disease amenable to therapeutic intervention by modulating arachidonic acid synthesis or metabolism with an oligonucleotide or oligonucleotide analog specifically hybridizable with RNA or DNA corresponding to one of the foregoing proteins are disclosed. Methods for treatment of diseases responding to modulation of arachidonic acid synthesis or metabolism are disclosed.
Abstract:
The present invention provides a method for bleaching or whitening a dairy product, comprising adding a lipoxygenase (LOX) to the dairy product. The method of the invention may be used to whiten milk, cheese, butter oil, cream or whey products. The invention further provides the use of a LOX to bleach a dairy product and a dairy product whitened by the methods of the invention.
Abstract:
Barley plants having reduced lipoxygenase-1 enzyme activity are provided, for example, barley plants expressing mutant LOX-1 protein. The barley plants of the invention are useful in the production of plant products such as malt and brewed beverages, particularly beer, having increased stability and reduced T2N potential.
Abstract:
Compositions and methods for modulating the activity of RNA are disclosed. In accordance with preferred embodiments, antisense compositions are prepared comprising targeting and reactive portions. The reactive portions preferably comprise one or two imidazole functionalities conjugated to the targeting oligonucleotide via linkers with or without intervening intercalating moieties. Therapeutics, diagnostics and research methods also are disclosed, as are synthetic nucleosides and nucleoside fragments that can be elaborated into oligonucleotides.
Abstract:
The present invention provides an enzymatic process for the prevention of development of pacha taint in CTC tea which comprises: (I) mixing an enzyme in water to form an enzyme solution; (II) spraying the enzyme solution homogeneously on rolled and distorted tea leafy material used in the black tea manufacturing process; (III) fermenting the enzyme solution sprayed rolled and distorted tea leafy material obtained at the end of step (II) (iv) drying the fermented material obtained in step (III). The enzyme can be mixture of any of lipase, lipoxygenase anel alcoholdehydrogenase.
Abstract:
The use of low concentrations of (a) PUFA (s) in an animal feed for monogastric and/or non-ruminant animals is disclosed to improve growth and feed conversion ratio. The concentration can be much lower than expected from the art, namely from 0.1 to 0.0001 g/kg feed, and yet still be effective. This may enable farmers to use lower concentrations of PUFA (s) in feed and hence reduce the cost of the feed. The feed may also have one or more antimicrobial enzymes present.
Abstract:
The invention relates to a method for producing plant lipoxygenases with modified position specificity, to the lipoxygenases obtained using this method and to the use of said lipoxygenases for hydroperoxylating substrates. In particular, the inventive LOXs provide the first means of producing novel gamma -linolenic acid derivatives on a large scale. To this end, gamma -linolenic acid is incubated with the inventive LOXs in suitable conditions as a substrate. The gamma -linolenic acid is then hydroperoxylated according to the LOXs mutants used, preferably in position 6 or position 9 or positions 6 and 9.
Abstract:
The present invention relates generally to a transgenic fruit-bearing plant having a foreign nucleotide sequence inserted therein which is substantially similar to a portion of the plant's fruit ripening specific lipoxygenase cDNA. Transgenic plants according to the present invention produce fruits having modified and surprinsingly superior ripening characteristics, including improved quality and texture, greater firmness, longer shelf life, better packaging and storage characteristics and improved processing characteristics. Also provided are transgenic fruits; transgenic plant cells; methods for making inventive transgenic plants, fruits and plant cells; methods for inhibiting lipoxygenase production in plants; isolated nucleotide sequences; and vectors comprising these isolated nucleotide sequences.
