This invention relates to fatty acid 13-hydroperoxide lyase protein from guava (Psidium guajava) and the gene encoding the protein. Expression systems for recombinant guava 13-hydroperoxide lyase and methods of using recombinant guava 13-hydroperoxide lyase for the production of green notes are provided.

A Novel Biodegradable Cationic Liposome for Intravenous and Intratracheal Gene Delivery

The present invention relates to synthetic cationic lipids, liposome formulations and the use of such compounds to introduce functional bioactive agents into cultured cells.

BMP-15 Compositions

Purified BMP-15-related proteins and processes for producing them are disclosed. DNA molecules encoding the BMP-15-related proteins are also disclosed. The proteins may be used in the treatment of bone and cartilage and/or other connective tissue defects and in wound healing and related tissue repair.

Model Uses PA1-1 Inhibitors

A method of testing a candidate composition for PAI-1 inhibition activity is disclosed. The method includes the steps of obtaining a transgenic non-human warm blooded vertebrate animal having incorporated into its genome a PAI-1 gene encoding a biologically active PAI-1 polypeptide, the PAI-1 gene being present in the genome in a copy number effective to confer over-expression in the transgenic non-human animal of the PAI-1 polypeptide; administering the composition to the transgenic non-human animal; and observing the transgenic non-human animal for determination of a change in the transgenic non-human animal indicative of inhibition of the activity of PAI-1. A transgenic non-human animal useful in such a method is also disclosed, as is a PAI-1 transgene construct encoding a biologically active PAI-1 polypeptide useful for preparing the transgenic non-human animal.

Nuclear Targeting Peptide Nucleic Acid (PNA)

A composition comprising a nuclear localization sequence and a peptide nucleic acid oligomer (NLS-PNA) is described. Uses of the composition include, but are not limited to: regulation of gene expression, gene therapy, and the production of pharmaceutical nucleic acids and proteins. In addition, the NLS-PNA is useful for scientific and therapeutic transfection and expression of nucleic acids in cells types that previously were resistant to transfection and therapy including quiescent cells, differentiated cells, embryonic stem cells, and eukaryotic cells with intact nuclear membranes. The NLS-PNA can be combined with a membrane transport sequence (MTS) forming a novel compound referred to as an MTS-NLS-PNA wherein the MTS provides transport through the cytoplasmic membrane of a cell. A nuclear targeted peptide nucleic acid oligomer is useful for the treatment of genetic based diseases and diseases that can be treated genetically including heart disease, cancer, cerebrovascular diseases, chronic pulmonary diseases, human immunodeficiency virus, and other diseases, conditions and disorders.

Analysis of Paralinguistic Properties of Speech for Near-term Suicidal Risk Assessment

Method and apparatus to measure jitter (period-to-period fluctuations in fundamental frequency) among the voices of suicidal, major depressed, and non-suicidal patients to predict near-term suicidal risk.

A Method for Genetically Engineering Proteins with Cell Membrane Translocating Activity

The invention describes a membrane-translocating peptide sequence (MTS) which facilitates entry of polypeptides and proteins into cells. Also described is an isolated nucleotide sequence encoding the membrane-translocating peptide and a method of using this sequence to genetically engineer proteins with cell membrane permeability. The MTS, and the method of genetically engineering proteins with cell membrane permeability, are useful for polypeptide and protein delivery for human and veterinary applications such as vaccine delivery and cancer therapy.

Ligation of Side-Chain Unprotected Peptides

A method of chemical ligation of peptides that requires no side chain protecting groups and no activation of the C-.alpha. carboxyl group is presented. The method consists of three steps. In the first step, initiation, a masked glycoaldehyde ester is enzymatically or chemically coupled to the C-terminal carboxylic acid of an sidechain unprotected first peptide. In the second step, ring formation, the masked aldehyde ester of the first peptide is unmasked, and then reacted with the N-.alpha. amino acid of a second sidechain unprotected peptide to form a ring structure. In the third step, rearrangement, the O-acyl ester linkage transfers at higher pH to an N-acyl linkage on the ring to form a peptide bond.

Cytochrome P450 Epoxygenase Induces Hypertension

The invention provides an isolated nucleic acid encoding the rat P450 2C11 arachidonic acid epoxygenase, or a human homologue thereof, having a mutation associated with salt induced hypertension. Also provided is an isolated cell line expressing the epoxygenase encoded by the mutated nucleic acid, and a non-human transgenic animal having a germ line insertion of the mutated nucleic acid. Also provided is a method of screening a compound for efficacy in treating salt induced hypertension comprising administering the compound to such a non-human transgenic animal, and detecting an improvement in the animal's hypertension. The invention also provides a method of screening a human subject for a genetic predisposition to salt induced hypertension comprising detecting a mutation in a human homologue of a rat P450 2C11 arachidonic acid epoxygenase gene which affects normal epoxygenase activity. Also provided is a method of treating salt induced hypertension in a human subject associated with a genetic mutation in a human homologue of the rat P450 2C11 arachidonic acid epoxygenase gene, comprising administering to the subject a functional metabolite, or analogue thereof, produced by the human homologue of the rat P450 2C11 arachidonic acid epoxygenase. Also provided is an isolated mutated rat P450 2C11 arachidonic acid epoxygenase, or a human homologue thereof, having a mutation associated with salt induced hypertension.

The invention relates to cell proliferation, cell differentiation, male infertility, male fertility and to compositions and methods involved therein. Also methods of culturing spermatogonial stem cells with bone morphogenetic protein 8 are disclosed.

Assay for Novel Serotonin Transporter Blockers

The mutant SERTs we have developed can provide for a platform to screen for novel modes/molecules interrupting SERT function. As SERT blockers are effective antidepressants, this strategy can lead to novel antidepressant medications. It may also be useful in development of animal models to test antidepressant action in vivo.
